In order to reveal the influences of super-thick and hard strata on abutment pressure and the evolution law of energy distribution in stope, a typical mining area of Yangliu Coal Mine was taken as the research object, and the variation law of abutment pressure and energy evolution process were simulated by numerical simulation method. The results are concluded as follows. (1) When there are super-thick and hard strata in the overlying strata, the advance abutment pressure in the middle and both sides of the working face is increased by about 9% and 5% respectively compared with that without super-thick and hard strata. This shows that when there are super-thick and hard strata in the overlying strata, the middle and both sides of the stope are in a high stress state for a long time. When the stope is disturbed by external force, it is more likely to lead to the occurrence of dynamic disasters such as mine earthquake and rock burst. (2) When there are super-thick and hard strata in the overlying strata, the change curve of the advance abutment pressure of the stope shows a cliff-like decline after breaking. When there are no super-thick and hard strata in the overlying strata, the change curve of the advance abutment pressure of the stope is gentler than that of the former. (3) With the continuous advancement of the working face distance, the peak value of the abutment pressure of the free side is increased by 3.60 MPa and 3.39 MPa respectively compared with the peak value of the abutment pressure of the mining side when there are or are not super-thick and hard strata in the overlying strata. The change trend of the side abutment pressure of the two is basically the same, but the side abutment pressure of the free side of the roadway is obviously larger than the lateral abutment pressure of the mining side of the roadway. This shows that the existence of super-thick and hard strata makes the stress concentration, roadway mining will be more prone to damage. (4) The super-thick and hard strata will cause great impact on the stope after breaking. Compared with the stope without super-thick and hard strata, the damage degree is more severe, the elastic energy released is more, and the influence range is more extensive.

为了揭示巨厚坚硬岩层对采场支承压力与能量分布演化规律的影响,以杨柳煤矿某典型矿区为研究对象,使用数值模拟方法对其支承压力的变化规律与能量演化过程进行模拟研究。结果表明:(1)覆岩中存在巨厚坚硬岩层时,工作面中部及两侧的超前支承压力分别比无巨厚坚硬岩层时增加了9%和5%左右,这说明当覆岩中存在巨厚坚硬岩层时,采场中部及两侧长期处于高应力状态,当采场受到外力扰动时,会更容易导致矿震、冲击地压等动力灾害的发生;(2)覆岩中存在巨厚坚硬岩层时,其发生破断后采场超前支承压力变化曲线呈现断崖式下降,覆岩中无巨厚坚硬岩层时,相较于前者,其采场超前支承压力变化曲线则较为平缓;(3)随着工作面距离的持续推进,覆岩中有无巨厚坚硬岩层存在时,其临空帮支承压力峰值比回采帮支承压力峰值分别增加了3.60 MPa与3.39 MPa,两者侧向支承压力变化趋势基本保持一致,但巷道临空帮的侧向支承压力明显大于巷道回采帮的侧向支承压力,这说明巨厚坚硬岩层的存在使得应力集中,巷道回采会更容易发生破坏;(4)巨厚坚硬岩层破断后会对采场造成巨大的冲击,与无巨厚坚硬岩层采场相比,其破坏程度更加剧烈,释放的弹性能更多,影响范围也更加广泛。
