摘要
“孤岛面”留小煤柱沿空掘巷,巷道矿压大,难以支护,通过实施锚杆支护技术,取得了较好的支护效果和经济效益。文章对“孤岛面”全煤巷锚杆支护技术应用做了简要介绍。
Short-pillars remain in 'islet faces'along the goafed road, which is difficult to support because of the heavier pressure on the road. The practice of pin timbering has obtained better supporting results and economic benefits. This paper briefly introduces the application of pin timbering of full coal road in 'islet faces'.
