摘要
以大柳塔煤矿新开43101薄煤层工作面的支护强度设计问题为工程背景,先计算出采场上方直接顶和基本顶的运动步距,并依据上覆岩层地质条件参数,构建出新开工作面的顶板结构模型。基于"以岩层运动为中心"的实用矿山压力理论思想,由所构建的顶板结构模型,计算出工作面顶板压力,从而确定工作面支架的合理支护强度。
Based on support strength design in face 43101 of Daliuta coal mine as an engineering background,firstly calculate pressure step of immediate roof and basic roof.Making using of results by mathematical calculation,then,can build a new model of roof structure.By practical underground pressure theory,which is based on rock movement,and through the new model of roof structure, can calculate roof pressure of newly opened working face 43101. According to the calculation results, finally determine its reasonable support strength.
