底板锚索及胶囊管帷幕注浆技术控制深井巷道底鼓研究
A research on cable supporting and curtain grouting of hydraulic hose controlling the roadway floor heave in deep coal mine
摘要
Abstract
According to the engineering conditions of the C15 haulage roadway at -960 m elevation in Xieyi coal mine, dynamic deformation characteristics of surrounding rock between the roof, two sides and the floor and the main reasons of floor heave have been obtained through monitoring the roadway deformation and analyzing floor heave factors. The results show that the main reasons of floor heave are the squeezing and flowing of fractured rock mass, which cause the stress and deformation of roadway release from the non-supporting floor. The comprehensive measures are put forward and put into prac-tice accordingly, including the roof and two sides grouting, floor cable supporting and curtain grouting of hydraulic hose. In addition, a self-manufacturing floor drilling machine is adopted to overcome the difficulty in drilling the cable holes. Facts have proved that the technology can effectively control the floor heave and keep the roadway stable for a long time in deep coal mine.关键词
