在对煤柱进行稳定性分析的基础上,采用概率积分法预测了8901工作面煤层变形破坏情况,即使在最不利的情况下,下部采空区对工作面的破坏也较小,不影响正常的掘进及回采工作。数值模拟分析表明,12煤煤柱虽然稳定性较差,但不会出现引起9煤波浪式沉降;结合现场钻孔探测,综合分析可知8901工作面长壁式开采是可行的。 Based on the stability analysis of coal pillar, the probability integral method was used to predict the deformation and failure of coal seam in 8901 working face. Even in the most unfavorable situation, the damage of the working face in the lower gob area was small and did not affect the normal Driving and mining work. Numerical simulation shows that although 12 coal pillars are less stable, wave settlement of 9 coal will not occur. Combined with field drilling detection and comprehensive analysis, the longwall mining of 8901 working face is feasible.
