delivered the opinion of the court.
This is an action on the case by appellee against appellant to recover damages for a personal injury *278occasioned by an explosion alleged to have been caused through the failure of appellant to have the roadways in the mine regularly and thoroughly sprayed, sprinkled and cleaned. A trial by jury in the Circuit Court of Fulton county resulted in a verdict and judgment against appellant for $200.
On January 5, 1906, at four o’clock p. m., appellee accompanied by Henry McGee, in the line of their duty as shotfirers, entered the coal mine of appellant for the purpose of firing 350 or 400 shots, which they had inspected earlier in the day. Having fired a large number of shots in the rooms in several entries, they proceeded to the second north entry for the purpose of firing fifteen shots in room Nos. 2, 3, 4, 6 and 7 in that entry. They commenced firing in room No. 7,'being the north room, and thence proceeded south firing shots in each of room Nos. 6, 4, 3 and 2 in the order named. After firing the shots in room No. 2, they proceeded south toward the main east entry a distance of 40 feet, when the explosion occurred which caused the injury complained of. It is not controverted that appellee was injured as the result of an explosion, but it is insisted that the explosion was caused solely by the accumulation of smoke and gases occasioned by the improper manner in which shots were fired; that dust, of itself, cannot produce an explosion; that the mine was wet and free from dust, and it was, therefore, impossible that dust particles could have aggravated the explosion, as alleged in the declaration.
It would serve no useful purpose to review in detail the testimony of the large number of witnesses, called on behalf of the respective parties to affirm and deny the presence of dust in the mine, and the failure of appellant to have the roadways sprinkled and cleaned. Suffice it to say that the evidence upon that issue was so close and conflicting as to render the verdict of the jury thereon conclusive in this court. It may be doubted, from the evidence in the case, whether *279the particles of dust which accummulate in a coal mine are capable, independently, of producing such an explosion as occasioned the injury to appellee, but it is admitted by all of the witnesses for appellant that such particles of dust will aggravate an explosion caused by smoke and gases in a coal mine coming in contact with the flame from shots, and we are of opinion that the jury were justified in finding that the explosion in question was aggravated by the presence of such dust, and that the presence of such dust was the proximate cause of the injury. Manifestly, the legislature conceived the presence of dust in a coal mine as liable to produce injurious results in explosions, when it enacted paragraph g of section 20 of the Mines and Miners Act, which reads as follows: “In case the galleries, roadways or entries of any mine are so dry that the air becomes charged with dust, the operator of such mine must have such roadways regularly and thoroughly sprayed, sprinkled, or cleaned, and it shall be the duty of the inspector to see that all possible precautions are taken against the occurrence of explosions which may be occasioned or aggravated by the presence of dust.”
It may be that appellee did not follow the most approved method of firing the shots, by firing in the same direction in which the current of air was carried, rather than in a direction against the current of air, but it cannot be contended with any force, that in so doing appellee was guilty of contributory negligence barring a recovery. Contributory negligence by a party injured is no defense to an action based upon the wilful failure of a mine operator to observe the requirements of the statute. Kellyville Coal Co. v. Strine, 217 Ill. 516. And the fact that the method of firing adopted by appellee had a tendency to cause a greater accumulation of gas and smoke at the mouth of the entry does not excuse appellant from the performance of its statutory duty with reference to sprinkling or cleaning its roadway, or absolve it from *280liability for an injury resulting from an explosion aggravated by the presence of dust in the mine.
It is insisted that the court erred in permitting the witness Thomas Back, .the county mine inspector, to testify on rebuttal as to the dusty condition of the second north entry on December 11, 1905. Several witnesses introduced on -behalf of appellant testified that the mine was naturally what is called a “damp mine,” and that the second north entry had a “bleeding” or “seeping” roof. In view of this evidence, which related to a permanent condition of the mine, we are of opinion that the testimony of the witness Back tending to show that the second north entry was dry and dusty on December 11, 1905, was competent, and that the objection of appellant that it related to a time too remote, was properly overruled.
We see no serious objection to the evidence introduced on behalf of appellee tending to sfyow that the entire mine was dry and dusty. Proof of the condition of the mine as a whole necessarily related to the condition of its several parts.
Finding no reversible error in the record the judgment will be affirmed.
Affirmed.
