无煤柱开采技术研究

Research on no-coal pillar mining technology

为提高煤炭资源回收率,缓解紧张的矿井接续,实现集约高效生产,采用无煤柱开采方案。本文详细说明了无煤柱开采方案的支护方式、矿压活动规律和支护强度,实现了相邻工作面无煤柱集中高效开采,保证了矿井持续高产高效。

In order to improve the recovery rate of coal resources, to ease the tension between the mining and preparing, to achieve intensive and efficient production, the use of no-coal pillar mining program. In this paper, the support method, mining pressure activity and the support strength of no-coal pillar mining was introduced in detail,, and realizes the mining of no- coal pillar of the adjacent working face, which ensures the continuous high yield and high efficiency of the mine.
