摘要
通过分析深部高应力软岩巷道失稳破坏规律,以某矿材料巷为研究对象,设计出锚杆锚索+钻孔卸压支护方案,并进行矿压、岩移量监测.从监测结果来看,巷道矿压显现明显减小,回采扰动对巷道的影响较小,巷道参数及断面设计合理.
Abstract
By analysing the destabilizing and damaging law of deep high stress soft rock roadway,and taking the material roadway of a mine as the engineering background,we designed the support scheme of anchor rods,anchor cables and drilling holes to release the pressure,and carried out the monitoring of mine pressure and rock displacement.From the monitoring results,the mine pressure of the roadway is obviously reduced,the influence of back mining disturbance on the roadway is small,and the roadway parameters and section design are reasonable.
