针对目前煤岩体锚固性能测试装置仅能人工检测锚杆滑动或者杆体破坏时的拉拔力,通过调研、理论分析、现场实测相结合的手段,研发一种实现连续监测拉拔试验中载荷-位移曲线,同时检测锚杆锚固力、锚杆位移和护表构件在煤壁的压入量,提高煤矿井下煤岩体锚固性能测试水平。
In view of the fact that the test device for anchorage performance of coal and rock mass can only detect the pulling force when the bolt slides or the rod is destroyed, a device for realizing the continuous monitoring of the load- Displacement curve, at the same time detecting the anchorage force of anchor rod, the displacement of anchor rod and the pressure of the guard member in the coal wall to increase the test level of anchorage performance of coal and rock mass in coal mine.
