锚网喷注支护技术在软岩巷道的应用

Application of Bolt and Grouting Support in Soft Rock Roadway

软岩、松软破碎厚煤层巷道支护问题一直困扰煤矿的发展。汪家寨煤矿对软岩、松软厚煤层巷道支护技术进行了研究,得出锚网喷注联合支护技术最适用于软岩、松软破碎煤层巷道的支护,并成功应用该技术,取得良好效果。

Supporting for soft rock and soft broken thick coal roadway has always been the problem limiting the mine development. In Wangjiazhai mine, the support technology was researched and the bolt and grouting support was proved to be the most suitable for the condition. The application of the technology has brought considerable benefits.
