摘要
根据斜沟煤矿13#煤层赋存情况,运用FLAC3D数值模拟方法对厚煤层综放开采主要影响因素进行研究,得到了各因素影响规律。各因素与顶煤破坏综合指标显著相关,对影响程度进行主次排序:埋深→煤单轴抗压强度→工作面长度→支架支撑力→煤厚。
Based on occurrence situation of 13# coal seam in Xiegou.Though FLAC3D numerical simulation method,the main influence factors law about thick seam mining is studied and the influence factors are obtained.Destruction of various factors and comprehensive index of top coal was significantly related.The extent of primary and secondary sort： the depth of coal seam→uniaxial compressive strength of coal→the length of working face in turn by the influence extent→the stents support force→seam thickness.
