通过对诚南煤业原始巷道锚杆支护设计的分析,结合15#煤层现场顶底板岩性条件,增大锚杆锚索预紧力和放大锚杆锚索间排距的方式,重新设计出了更加合理的支护形式。
Through analyzing the original design of bolting supporting in coal roadway of Chengnan Coal Mine, combining with the top and bottom lithology conditions of 15# coal seam, increase the anchor bolt pre tightening force and enlarged anchor spacing, design a more rational supporting form again.
