摘要
煤矿巷道施工后在短时间内顶板帮部巷道变形,巷道出现锚杆、锚索托盘变形、顶板出现网兜坠顶、两帮出现不同程度的鼓出等现象。通过优化支护参数、加强支护措施等效果较好,进一步保障了矿井安全生产。
After the construction of coal mine roadway,in a short period of time,the roof side of the roadway deformation,roadway bolt,anchor cable tray deformation,roof net bag falling roof,two sides appear different degrees of bulge and so on.By optimizing the support parameters and strengthening the supporting measures,the effect is better,and the safety production of the mine is further guaranteed.
