摘要
尹家沟煤矿 3110 掘进工作面运输顺槽和切眼围岩存在变形严重、支护工程量大的问题.根据 3110工作面顶板条件和施工条件,采用水力压裂技术施工,并选取部分地块进行工业性试验,经过监测数据的分析发现,巷道两帮和顶板的变形量均有一定程度的减弱,其中底鼓变形量的降低最为显著.
Abstract
There are serious deformations and a large amount of support work in the surrounding rock of the transportation channel and cutting hole of the 3110 excavation face in Yinjiagou Coal Mine.According to the roof conditions and construction conditions of 3110 working face,hydraulic fracturing technology is used for construction,and some plots are selected for industrial test.Through the analysis of monitoring data,it is found that the deformation of the two sides of the roadway and the roof has been reduced to a certain extent,and the reduction of floor heave deformation is the most significant.
