深部开采巷道的锚杆支护技术分析

Technology Analysis of Deep Roadway Bolt Support

由于多年的开采,浅部易开采的煤炭资源日益减少。随着开采深度的增加,支护问题愈趋严重,直接影响煤矿安全生产,危及人身安全。锚杆支护是巷道经济、有效的支护形式,其在深部巷道支护中已得到广泛地应用。现通过理论分析,验证了锚杆支护技术能够保证深部巷道支护的可靠性。

Due to years of mining, the shallow coal area that easy to exploit is fewer and fewer. With the increase of mining depth, the bolt support problem is getting more and more serious, directly impacts on the production of coal mine safety and endangers personal safety. The Bolt support is the economy and effective form for roadway. And it has been widely used in deep roadway support. The theoretical analysis proves that the bolt technology can ensure the reliability of deep mine roadway support.
