摘要
通过采取坑道透视、钻孔资料及实际巷探等方法对石炭二叠纪山4#煤层煌斑岩侵入区域进行研究并预测侵入范围,有效地解决了工作面布置及提高资源回收率。并通过煌斑岩侵入区域分析,提前制定应对措施,保证工作面按照设计进行掘进及开采。
The lamprophyre intrusion area is studied and the intrusion range is predicted in 4# coal seam of the Carboniferous-Permian mountain by using the methods of roadway perspective, drilling data and actual roadway prospecting, they effectively solve the working face arrangement and improve the recovery rate of resources. According to the analysis of the lamprophyre intrusion area, the measures are formulated in advance to ensure driving and mining of the working face according to the design.
