小煤柱开采技术应用分析

Analysis of the Application of Small Coal Pillar Mining Technology

以小煤柱开采为着手点开展深入探究,分析巷道围岩变形特征和小煤柱护巷原理,结合工程实例对小煤柱留巷技术的应用开展分析,实践结果表明小煤柱配合相应的支护工艺能够在确保矿井生产安全的同时实现资源充分利用。

This paper further studied small coal pillar mining technology, analyzed the characteristics of the deformation pattern of roadway surrounding rock and the principle of roadway protection with small coal pillars and carried out the analysis on the application of roadway retaining technology of small coal pillars combined with the practical engineering. The results showed that the combination of small coal pillar with corresponding supporting technology could ensure the safety production in coal mines and full use of resources.
