近距离煤层采空区下锚网索支护技术研究与应用

Coal Seam Goaf Anchor Rope Supporting Technology Research and Application of Near Distance

随着开采进度加快,近距离煤层采空区下掘进开采已成为发展趋势。因此,摸清围岩变形规律,采用合理有效的支护方式,控制围岩的变形,满足现场安全生产需要成为急需解决的问题。本文阐述了平煤八矿首次在近距离采空区下大断面切眼采用锚网索支护技术的原理,并介绍了所取得的成功经验和经济效益,为平煤八矿在同类条件下巷道施工提供了很好的借鉴。

With the accelerated progress of mining, close coal seam mining area under the mining and mining has become the development trend. Therefore, to understand the law of deformation of surrounding rock, the use of reasonable and effective way to support the control of the deformation of the surrounding rock to meet the needs of the safety of the scene to become an urgent need to solve the problem. This paper expounds the principle of using anchor cable support technology in the large section cut-off area in the close-up mined-out area for the first time, and introduces the successful experience and economic benefit. In the same condition Roadway construction provides a good reference.
