煤矿深部含水层突水规律的研究
Study on water bursting regular pattern at deep water-bearing strata
-
摘要: 在煤矿生产的初期,对煤矿生产有影响的是浅部含水层,深部含水层对煤矿生产影响不大。随着煤矿生产开采深度的增加,矿井水压越来越大,因此深部含水层对煤矿生产的影响越来越严重。深部含水层由于水压高,含水性强,所以出水不仅量大、迅猛,而且治理难度大。本文总结了深部含水层的特点和突水规律。这些规律对于搞好煤矿防治水工作具有十分重要的意义。Abstract: In the early stage of coal mine production, the shallow water-bearing strata are the main factors that affect the mining safety, whereas the deep water-bearing strata have little effect on coal production. The water pressure of the coal mine is increasing quickly with the increase of the mining depth. Therefore, the impacts of deep water-bearing strata on coal production become more and more serious. The high water pressure and quosity in deep water-bearing strata not only cause the water inrush become more violent and swift, but also gush much more water. All of them greatly enhance the difficult of controlling water inrush. Major characteristics and the water bursting regular pattern in deep water-bearing strata were systematically summarized in this paper. Therefore, this paper has an important meaning to the mine water control work.WT
