极近距离煤层开采方法的确定
|
摘要
合理开采方法的选择对极近距离煤层的安全开采十分重要。以某矿极近距离煤层实际地质条件为研究背景,提出下行开采和合层综放开采2个初步方案,并利用理论计算对2种方案的可行性进行分析,结果表明两种方案均具有一定的可行性。综合考虑技术和经济两方面因素,最终决定采用极近距离煤层下行开采的方法。
The selection of reasonable mining method is very important for the safe mining of the very close coal seam. Take a coal mine as the research background, the downward mining and full-mechanized caving mining is put forward, and the feasibility of using the theoretical calculation of two kinds of schemes were analyzed, and the results show that the two schemes have certain feasibility. Taking into account both the technical and economic factors, the ultimate decision is to adopt the method of downward mining by extremely close coal seam.
