摘要
刘店矿首采区在开采时发现断层较多,煤层厚度不稳定,给矿井施工和生产带来很大困难。根据收集的资料,总结了首采区主采煤层的顶底板岩性、厚度及变化、结构等特征,从沉积环境及变化、岩浆岩的侵蚀和断层构造等方面分析了首采区煤层厚度变化原因。
Unstable thickness and fault structure of coal bed in the first coal mining area of Liudian Mine bring great difficulty in mine construction and production. In this paper, the lithology of roof and floor, the changes in thick- ness, the characteristics of structure of the main coal bed in the first coal mining area are summarized based on the collected data. Besides, the cause of the changes is analyzed from the sedimentary environment and its change, the erosion of magmatic rock and fault structure.
