摘要
基于目前掘进工作面前探梁临时支护的局限性,介绍了ZJC2X1040/30/42型综掘超前支护装置在王庄煤矿62B2风巷工作面的应用。实践证明,该超前支护装置操作简单、支护强度高,能够实现全断面主动支撑顶板,性能可靠,安全保障系数高,值得推广应用。
Based on the limitations of probe beam temporary support of on current excavation work, it has introduced ZJC2X1040/30/42 fully mechanized digging forepoling device for 62B2 Wind Tunnel Face in Wangzhuang Coal Mine. Practice has proved that the advance support device is simple to operate, supporting high - intensity, full - face active support to achieve the roof, reliable performance, safety and security factor, should be widely applied.
