煤炭属于一次性非可再生能源,所以未来社会煤炭只会越来越宝贵、越来越稀缺。因此,在煤炭资源开采中,如何减少资源的浪费与损失,合理的规划现有资源,选择先进的开采工艺以减少煤炭资源的损失,已成为迫切需要解决的问题。本文针对冯家坛煤矿020109工作面进行旋转开采,保证了工作面采煤的连续性,延长了工作面的长度,减少了搬家次数。该技术有效提高了工作面回采工效,增加边角煤的回收,提高了煤炭资源的采出率。
Coal is a one-time non-renewable energy source, so future social coal will only become more and more precious and scarce. Therefore, in the exploitation of coal resources, how to reduce the waste and loss of resources, reasonably plan existing resources and choose advanced mining technology to reduce the loss of coal resources has become an urgent problem to be solved. In this paper, rotary mining is carried out for the 020109 face of Fengjiatan Coal Mine, which ensures the continuity of coal mining on the working face, extends the working face length and reduces the frequency of moving. This technology effectively improves working efficiency of coal mining, increases the recovery of corner coal, and improves the recovery rate of coal resources.
