| 摘 要： | 以淮南矿区地面钻孔抽放试验为基础,运用现场考察数据分析和数值模拟相结合的研究方法,分析了地面钻孔的稳定性,得出了和以往不同的认识。认为钻孔的破坏是随着工作面推进而发生的动态过程,布置在靠近回风巷侧钻孔更加稳定。

| Abstract: | Based on the methane drainage experiment by surface boreholes performed in Huainan mining area,through field investiga- tion and numerical simulation,the stability of borehole is analysed,and a result,which is different existing judgement,is obtained. The result shows that the borehole destruction occurs in the dynamic process of coal face advancing,and it is more stable when the borehole location is close to tailgate. |
