本文通过现场实测,提出煤层底板岩体在采场前方超前压力压缩段内形成自下而上的岩体原位张裂,并描述了“原位张裂”的形成过程,从而合理地解释了承压水上采煤的底板突水机制。
Based on field measurements, this paper puts forward that in-situ fractures of rock mass formed from bottom to top in the compressive section of coal seam bottom strata ahead of stope and describes the formation process of “in situ fracture”, so as to explain reasonably Floor water inrush mechanism of coal mining on pressure water.
