摘要
王家岭煤矿地表为凹凸不平山体,煤层埋深较浅,地表山体对工作面回采矿压显现影响明显,导致工作面回采过程中矿压显现异常。通过实验室物理相似模拟试验,研究山体产状以及工作面相对于坡体回采方向对工作面矿压显现的影响。
The surface of Wangjialing mine is mountainous topography and the buried depth of coal seams is relatively shallow, so the surface of the mountain influenced mining pressure obviously and the process of mining face appeared abnormal pressure. Through the laboratory physical analog simulation test to study the influence of the mountain occurrence and the direction of mining face on the mine pressure.
