在煤矿开采活动中,随着开采深度的提高,矿山的深部压力问题也日益突出,这就使得巷道支护与布置工作面临较大难度。回采巷道因支护成本及服务年限等因素的限制,支护质量难以保证。而锚杆支护技术被应用到煤矿巷道掘进中,不仅可大幅减少材料消耗,而且还能在巷道的稳定性发面发挥重大积极作用。本文就锚杆支护技术在煤矿掘进巷道中的具体应用,进行了详细的探究。
In coal mining activities, with the improvement of mining depth, the problem of deep pressure of the mine is also increasingly prominent, which makes the roadway support and layout work more difficult. Mining roadway due to support costs and service life and other factors, support quality is difficult to guarantee. The bolt support technology is applied to mine roadway excavation, not only can greatly reduce the material consumption, but also in the stability of the roadway play a significant positive role. In this paper, the application of bolt supporting technology in coal tunneling is discussed in detail.
