摘要
为进一步增强煤矿生产安全,在对某矿切眼断面地质、煤层等条件分析的基础上,基于拱形、等效圆、等效椭圆设计方法对锚杆、锚索支护参数进行设计,并结合该矿切眼断面确定最终支护参数;最后,通过设计监测方案,重点对围岩位移变化进行监测,验证所设计支护参数的支护效果,并取得理想结果。
On the basis of analyzing the geology and coal seam conditions of a mine's cut eye section,we design the anchor rods and anchor cable support parameters based on the arch,equivalent circle and equivalent ellipse design methods,and determine the final support parameters by combining with the mine's cut eye section;finally,we validate the support effect of the designed support parameters by designing a monitoring program focusing on the displacement changes of the surrounding rock and obtaining the ideal results.
