无煤柱自成巷技术在凌志达矿15501工作面的应用

Application of self-forming roadway without coal pillar technology in 15501 working face of Lingzhida mine

本文在分析凌志达矿15501工作面实际地质条件的基础上,提出了该工作面应用无煤柱自成巷技术的具体方案,现场应用之后取得了良好的留巷效果,不仅减少了回采巷道掘进工程,而且保障了矿井采掘衔接,还能够大幅提升资源回收率,从而实现矿井可持续发展。

Based on the analysis of the actual geological conditions of 15501 working face in Lingzhida coal mine,this paper gives the specific plans of self-forming roadway without coal pillar technology application.After the field application,the good effect of retaining roadway is achieved,which not only reduces the excavation engineering of mining roadway,but also ensures the connection of mining and excavation,and greatly improves the resource recovery rate,so as to realize the sustainable development of the mine.
