锚杆支护技术在煤矿掘进巷道中的应用

Application of bolt supporting technology in coal mine driving roadway

随着煤矿开采活动的不断深入,矿山深部压力问题也变得越来越严重,增大了巷道支护与布置工作的难度。且因支护成本及年限等因素的限制,拉低了巷道支护的质量水平。为此,应在煤矿巷道掘进过程中采用锚杆支护技术,以大幅度减少材料的消耗量,增强巷道的稳固性。本文通过分析煤矿掘进巷道支护存在的问题,指出了锚杆支护技术在掘进巷道中的具体应用。

With the deepening of coal mining activities,the deep pressure of mine has become more and more serious,increasing the difficulty of roadway supporting and layout work.And the supporting cost and the service life and other factors reduce the quality of roadway supporting.Therefore,the bolt supporting technology should be adopted in the tunneling process of coal mine to greatly reduce the consumption of materials and enhance the stability of the roadway.This paper analyzes the problems existing in the supporting of roadway in coal mine,and points out the specific application of bolt supporting technology in roadway driving.
