摘要
针对公乌素地区16号煤层实际情况,运用正交试验方法和FLAC3D软件对顶煤破坏影响规律进行研究,得到对工作面控顶区内顶煤破坏影响因素的主次排序:埋深>煤单轴抗压强度>工作面长度>支架支撑力>煤厚。
According to the actual storage conditions of No. 16 coal seam in Gongwusu area, the orthogo- nal experimental design method and FLAC3D were applied to study the effect law of top coal damage. Re- search showed that the primary and secondary sequence of the five factors on top coal damage effects in fully mechanized top coal caving mining was ： the coal deep 〉 the uniaxial compressive strength of coal 〉 the length of working surface 〉 the anchorage force of stents 〉 the thickness of coal seam.
