Pingdingshan Coal Group:preventive and control technology against roadway floor heave in its coal mines

随着矿井开采深度的不断增加,巷道底鼓问题日趋严重,巷道底鼓已成为巷道支护中最难解决的问题之一。论文结合平煤集团各矿的生产实际,通过分析巷道底鼓原因和形式,提出了巷道底鼓防治措施,现场应用表明,采用综合防治底板底鼓措施能够有效预防和治理矿井巷道底鼓。

With the increase of mining depth, floor heave becomes more and more serious which presents one of the hardest to handle problems in roadway maintenance. On the basis of the actual coal production practices plus analysis of the reasons and phinomena of roadway floor heaves in the coal mines affiliated to Pingdingshan Coal Group, the on--site application of the preventive and control measures against roadway floor heave proposed by this paper indicates that the employment of these comprehensive measures against roadway floor heave can effectively prevent and control the said longstanding problem.
