摘要
针对兴隆庄煤矿的实际情况,结合实际地质资料,运用数值模拟软件,研究临近开采地堑区工作面应力分布和靠近2#断层开采时不同宽度梯形煤柱对运顺和1310工作面的围岩垂直应力及煤层顶板垂直应力。
Aiming at the real situation of Xinglongzhuang coal mine,use the numerical software to research the stress of working face close to mining graben area,the surrounding rock stress and coal seam vertical stress for different width trapezoidal coal pillar to roadway and 1310 working face when mining is close to No.2 fault.
