摘要
通过对童亭井田各可采煤层顶底板特性分析,对不同顶底板岩性及采掘中遇见的问题进行了说明,为矿井地质工作人员设计、施工提供了可靠的地质依据,以更好地为矿井生产服务。
Based on analysis of characteristics of the roof and floor of each minable seam, this paper demonstrated some common issues occurring in underground working activities, providing reliable data for helping shaft geologists with their engineering design and construction and then contributing to mining activities in a better way.
