delivered the opinion of the Court:
On the 15th day of June, 1881, the plaintiffs in error brought an action on the case, in the Madison circuit court, against the defendant in error, for an alleged injury to certain coal mines belonging to the plaintiffs. There was a trial before the court and a jury, upon issues of fact, resulting in a verdict and judgment for the defendant, which was subsequently affirmed by the Appellate Court for the Fourth District. Counsel for plaintiffs make no complaint in the argument filed, of the rulings of the circuit court upon questions of evidence, but ask a reversal solely on the ground the jury were not properly instructed on the trial, as to the law of the case.
The record discloses substantially the following state of facts: The plaintiffs and defendant, before and at the time of the alleged injury, were engaged in mining coal from their respective lands, which lie contiguous to each other, and their several parcels constituted a part of a large body of coal lands lying near North Alton, belonging to various coal operators, and known as the “coal branch. ” The lot of land belonging to the plaintiffs contains twenty acres, and lies in the extreme north-east corner of the coal branch, and is bounded on the south by the defendant’s land. The tract of the defendant contains seventy-eight and one-half acres, and in part lies immediately south of the plaintiffs’ tract, but being much wider than theirs, it extends considerably farther west. The coal branch mines all “dip” from the south-west to the north-east, so that upon the removal of the coal from any of them, the water accumulating therein would, if unobstructed, naturally flow into the plaintiffs’ mines. Prior to the injury complained of, the plaintiffs had sunk two shafts on their land,—one about the centre, and the other, near the dividing line between them and the defendant. The two mines of the plaintiffs were, as seems to have been the custom, connected, so as to afford a passage from one mine to the other. Most of the coal properly belonging to the south mine had been removed before the present controversy arose. In drifting south, the plaintiffs, presumably by mistake, had crossed the line between them and the defendant at the north-east corner of the land of the latter, and had removed the coal for a distance of some ninety-five feet, by means of which mine No. 1 of plaintiffs, and No. 7 of the defendant, were connected. Mine No. 7 was also connected with another mine of the defendant, a short distance in a south-west direction from the latter, known as mine No. 6. Those two mines were originally dry, and were both worked at the same time. In drifting west in No. 6, the defendant broke into No. 5, an old abandoned mine of his. West and north-west of No. 5 is an extensive area of territory, consisting of old, abandoned mines belonging to various parties, all of which, in process of mining, had become connected, so that the water in most of them, which had been accumulating for years, was constantly pressing down and forcing its way towards the mines of the plaintiffs and the defendant; yet its progress was arrested at mine No. 5 of the defendant, so long as that remained unconnected with the mines below it. When, however, No. 5 became connected with No. 6, as heretofore stated, the water at once commenced making its way through No. 5 into No. 6, and so continued until about a year after-wards, when the defendant found himself unable to control the water which was rapidly forcing its way into No. 6.
The usual method which prevailed at the coal branch of getting rid of water in the mines, was to collect it in a sump or basin excavated near the mouth of the pit, and hoist it to the top of the shaft in barrels. When, however, the accumulations became so great that the water could not be disposed of in that way, except at a cost that would not pay to take out the coal, it was the custom or usage, under such circumstances, for the owner of the mine to protect himself from the aggressions of the water as best he could, by the erection of a dam or other like means. Thus, Walton Rutledge, a surveyor and mining engineer, and one of plaintiffs’ own witnesses, testifies: “It is customary to make a dam whenever necessary. The rule all work by, is for each person to protect his own mine against water. ” The defendant being no longer able to control the water in No. 6, as above stated, was forced to abandon it. But with a view of preventing the water, which he could no longer control, from forcing its way into No. 7, and driving him out of that also, he determined to build a strong dam between No. 6 and No. 7, so as to confine the water in No. 6, which he accordingly did, and thereupon abandoned No. 6 altogether. Had this not been done, it is clear the water would have not only destroyed the defendant’s remaining mine, No. 7, but would have passed on through that into the plaintiffs’, and thus have destroyed all of them long before the alleged injury occurred, unless the plaintiffs’ had adopted similar measures for their own protection, by building a like dam between their own mines. Some four years after the building of the dam by the defendant, during which time it protected, as we have just seen, the plaintiffs’ and defendant’s mines alike, it finally, by reason of the constantly increasing pressure, gave way, when the long pent up waters poured down through mine No. 7 of the defendant, into the mines of the plaintiffs, overflowing and submerging them in water. The plaintiffs in the present action seek to recover from the defendant damages alleged to have resulted from the breaking of the dam, and the consequent flooding of their mines.
It further appears that some two years before the breaking of the dam, to-wit, on the 25th of March, 1874, the defendant leased his entire mines for a period of ten years, commencing on that day and ending on the 25th of March, 1884, to Thomas Hamilton and Thomas Cunningham, who at once took possession and control of the mines under their lease, and so continued in possession and control of the same up to the time of the breaking of the dam. That the dam, when • built, was sufficiently strong and properly constructed, is not only settled by the finding of the Appellate Court, but is conclusively shown by the fact that it effectually withstood the constantly increasing pressure of the'-accumulating waters for some two years after the leasing of the mines, making about four years altogether from the time it was built.
Under this state of facts the plaintiffs asked the court to give the jury the following instruction, which the court refused to do, and the plaintiffs excepted:
“If the jury believe, from the evidence, that there was a dam erected in one of the main leads or ways of the coal mine of the defendant, either by the defendant, or his lessee, by and with his knowledge and consent, and that 'by reason of such dam being erected the natural and ordinary flow of the water percolating and flowing through said mine was checked, and thereby accumulated in the mine of said defendant in a large and unusual quantity back of and behind said dam, whereby said dam broke and gave away, and precipitated with an irresistible force a large and unusual quantity of water in and upon the mine of the plaintiffs, and drowned out and destroyed the same, then the jury must find for the plaintiffs. ”
We agree with counsel for plaintiffs in error that this instruction fairly presents the legal theory upon which the plaintiffs must recover, if they can recover at all. On the other hand, if the instruction can not be sustained on legal principles, the judgment is proper, - and should not be disturbed, even conceding some of the instructions for the defendant in error are not technically accurate.
It was contended by the plaintiffs, on the trial below, that the defendant was guilty of negligence in operating his mines in such a maimer as to connect them with the old abandoned mines lying west and north-west of his own, by means of which, as we have seen, the amount of water.flowing into mine No. 6 was so increased as to become uncontrollable by the ordinary method of collecting it in a sump, and hoisting it in barrels to the top of the shaft. It was also contended that notwithstanding this increase of water, the defendant, by the exercise of reasonable care and diligence, might have hoisted it to the top of the mine in the manner stated, and that hence there was no necessity for building the dam. It was further contended that the dam was not made sufficiently strong at the outset, and that there was also negligence in not keeping it in repair. There was, moreover, a sharp conflict in the evidence as to what was the custom or usage at the mines respecting these matters, and also as to whether the defendant had conformed to such usage or custom. The refused instruction, however, ignores all these issues of fact which were submitted to the jury, and declares, as matter of law, that in order to entitle the plaintiffs to recover it is only necessary for them to show the building of the dam by the defendant, the accumulation of water behind it, and its subsequently giving away and flooding the plaintiffs’ mines. If such be the law, much labor and time might have been saved by excluding all evidence offered on those issues', with the exception just stated.
We are clearly of opinion the instruction in question was properly refused. The reasons which lead to this conclusion may be stated very briefly.
The case in hand, modified somewhat by special circumstances, is, in most of its essential features, like many others to be found in the books. It is a controversy between owners of adjacent mines, where, as is usually the case, the mine of the defendant is upon a higher plane than that of the plaintiffs, and tlm complaint is, that waters improperly pent up in the defendant’s mine have escaped and flooded that of the plaintiffs. The question then arises, what are the mutual rights and duties of the owners of adjacent mines thus situated ? The answer to this question will present the general view which we entertain of the law as applicable to this case, and the one which we think is fully sustained by the authorities. We understand that each owner of mines thus situated has the right to take out all the coal within the limits of his own boundaries,—that is, each may work to the dividing line in every direction, but of course can not cross it without becoming a trespasser. While this is so, common prudence and self-interest would say the owner of the lower mine, when danger from water is apprehended, as is generally the case, should not work up to the dividing line between himself and the upper owner, but should leave a wall of coal within his own boundaries, of sufficient width and strength to protect him from the encroachments of the water from the upper mine, which, if unobstructed, would necessarily flow into his own. Where there is a mining district consisting of numerous connecting mines, and those at the upper part of the dip, or on the higher level, have been mined and abandoned, it is clear the waters gathering and percolating through them will, by force of the law of gravitation, be thrown in a body upon the first mine below which is being worked, in which ease, if the owner is not able to protect himself from the water thus concentrated, by the ordinary methods of pumping or hoisting it to the top of the shaft in barrels, it is manifest he must either abandon the mine altogether, or resort to some other more efficacious means to prevent a loss of his property. Such is exactly the case here.
The question then arises, what duties does the owner of the mine having this increased burden and peril cast upon it, owe to the proprietor of the one immediately below him, where such proprietor has failed to take any precautionary steps for his own protection, as was the ease here. If the upper proprietor is unable to profitably work his mine without building a dam across the way leading into it from above, may he do so ?—or must he abandon his own mine altogether rather than incur the risk of the dam ultimately giving way and precipitating the water thus accumulated in undue quantities, upon himself and the owner below, before the latter has been able to take out all of his coal? Under the circumstances stated, we do not understand the law requires the owner of the upper mine to so abandon his property in order to avoid such a contingency as that suggested. 6On the contrary, we are of opinion he has the right to build the dam, and if in doing so he exercises ordinary care and skill, he will not be held liable for the consequences should it subsequently give way without his fault. While it is customary for the owners of mines to keep them as free from water as practicable, yet they are not bound by law to do so. The only obligation resting upon them in such respect, is that of self-interest. The upper owner may abandon his own mine whenever he pleases, notwithstanding his doing so may largely increase the flow of water into the mine below, and thereby greatly enhance the labor and expense of the owner in operating it. So the owner of a mine, for the purpose of protecting himself from the encroachments of water, which is regarded as the “common enemy” of mines and mining inter-', ests, may erect a dam or any other structure on his own premises, if necessary for such purpose, subject to the limitation that such dam or other structure does not have the effect to collect water from adjacent territory, and eventually cast it upon a lower mine, which but for such dam or other structure would not have reached it.
There is another consideration which, in our judgment, forbids a recovery in this case. Two years before the breaking of the dam, as has already been seen, the defendant leased the mines to others, who took immediate possession of the same, and continued in possession up to the time the dam gave way, and there is not the slightest ground for the claim that the defendant is liable for the consequences of the dam’s ultimate failure, unless the position assumed by the refused instruction can be maintained, namely, that'its construction at the outset was per se a nuisance, which we are satisfied, as already indicated, is not the law. We hold the building of the dam was a lawful act, clearly justified by the circumstances under which it was built. When built it fully answered the purpose for which it was constructed, and so continued long after the defendant had leased the mines. It successfully resisted the constantly increasing pressure, resulting from the daily accumulation of the water, for about four years, protecting the mines of the plaintiffs and defendant alike. The general view here taken is fully sustained by the following authorities: Gould on Waters, 294; Bainbridge on Mines, (1st Am. ed. from 3d Gould’s ed.) 394; Alton v. Blundell, 12 M. & W. 324; Smith v. Kenrick, 7 Com. B. 515 ; Baird et al. v. Williamson et al. 15 id. 375; Everett et al. v. Hydraulic Flume and Tunnel Co. 23 Cal. 225; Leading Cases on Mines and Mining, 629.
The judgment-will be affirmed.
