针对平煤股份一矿丁_6-32030综采工作面顶板破碎、片帮、掉顶频繁等问题,采用管缝式锚杆支护技术对破碎顶板及松软煤体进行了支护。应用结果表明:管缝锚杆增加了松软煤体及破碎顶板的整体强度,使不易控制的煤岩体变为相对稳定的煤岩体,有效地解决了片帮、掉顶问题。
In view of the problems such as the roof crushing, the piece gang and the falling top frequently in the No.1 Dingang Mine6-32030 of Pingdingshan Coal Mine, the fractured roof and loose coal are supported by the seam bolt support technology. The application results show that the pipe anchor increases the overall strength of the soft coal and the broken roof so that the hard-to-control coal rock mass becomes a relatively stable coal and rock mass, effectively solving the problems of sheet metal roofing and roof falling.
