带压开采对采场底板的破坏规律研究

Study on the damage law of mining floor under pressure

本文针对挖金湾虎龙沟煤矿5^#煤层东盘区81511回采工作面带压开采下对采场底板的破坏,通过数值模拟试验对煤层下方底板进行加压以求达到与原开采工作面带压开采相类似效果,为矿井安全生提供了参考数据。

This paper aims at the destruction of the floor of the stope in the pressure mining of the 81511 working face in the East panel of the No.5 coal seam of Wajinwan Hulonggou coal mine.Through the numerical simulation test,the floor under the coal seam is pressurized to achieve the similar effect with the pressure mining of the original working face,which provides the reference data for the safety production of the coal mine.
