摘 要:以跃进煤矿弱冲击区域25020下巷掘进巷道为试验区域,分区段采用锚网索+36U圆弧拱棚、锚网索+36U可缩梯形棚、锚网索无架棚3种方案进行支护试验,通过对比分析各自支护条件下巷道顶板下沉情况,确定锚网索无架棚支护效果,并总结出该支护形式巷道顶板下沉规律,为该矿冲击地压煤巷掘进提供新的有效支护选择。Taking the weak rock burst excavation roadway of 25020 in Yuejin mine as the experimental region, the experiment use three supporting schemes that had cable anchor with 36U shed, cable anchor with telescopic 36U shed of ladder, and cable anchor without shed, by comparativing and analysing the situation of tunnel roof subsidence in the different regions to determine the supporting effect with cable anchor without shed, and summarizing the regularity of tunnel roof subsidence in the support form. The conclusion provides the new effective choice for coal roadway drivage with rock burst.
