以白洞矿C3#煤层301盘区8108工作面开采条件为基础,应用相似材料模拟方法,研究了开采后上覆岩层运动的过程、变化及特点,探讨了上覆岩层运动的规律及煤壁失稳情况;根据模拟结果,分析了开采范围内支承压力峰值的变化及对顶板的影响。
Overlying strata of No.8108 working face,301 panel,NO.C3 coal seam in Baidong coal mine is material simulated to study the movement law and instability characteristic.Based on the test result,the change of maximum abutment pressure as well as whose effects on roof is also analyzed.
