通过对9~#煤的开采现状分析,分别从露天开采及井工开采方式的角度考虑,提出了2种开采方案,2个方案中首先考虑了露天开采的可能性,确定了露天开采时9~#煤层的开采工艺、开采程序、开拓运输系统等;同时对井工滞后露天开采方案的实施可行性进行了判断。最终确定9~#煤层露天开采方案是最科学、有效、适宜的开采方案。 Based on the analysis of 9 ~ # coal mining status, two kinds of mining schemes are proposed from the perspective of open pit mining and underground mining respectively. In the two schemes, the possibility of open pit mining is first considered, and when open pit mining is determined, 9 ~ # Seam mining technology, mining procedures, development of transport systems; at the same time, the feasibility of the implementation of open pit lag mining program was judged. Finally, it is the most scientific, effective and suitable mining scheme to determine the open pit mining scheme of 9 ~ # seam.
