摘要
根据矿上资料,结合10号煤层现场条件,通过数值模拟的方法,研究了采空区上覆岩层采动裂隙场的演化规律、分布形态及范围以及破坏程度,最终为上邻近层的采动卸压瓦斯抽采提供理论基础,对瓦斯抽采钻孔或巷道的布置及参数选择具有重要的指导作用。
According to the data of mine, combined with the field condition of No. 10 coal seam, the evolution law of the overlying strata is studied by means of numerical simulation, and the distribution and extent of the overlying strata are studied.
