摘要
为解决百善煤矿上限区域煤层巷道支护维修困难等问题,文章基于上限开采区域地质条件,确定出上限区域煤巷锚杆支护的基础参数,研发出"三段铰接矩形"式桁架,提出"锚杆—桁架"联合支护方案,并进行工程实践应用,取得较好的支护效果。
In order to solve the support problems of the coal roadway extremely difficult to maintain in the upper limit region. Based on the geological conditions of the upper limit area,the basic parameters of the coal roadway bolting in the upper limit area were determined, ＂three- section articulated rectangle＂truss was developed and the ＂bolt- truss＂combined support technology was proposed. The proposed technology received favorable supporting effect in engineering practice.
