一次采全高采煤法在30万t/a矿井中的应用研究

Study on the Application of One-Time Full-High Mining Method in a 300,000 t/a Mine

山西晋煤集团大峪煤业有限公司矿井为兼并重组整合项目,结合矿井实际,对采煤方法进行优化,在工作面生产能力不变的前提条件下,尽量简化回采工作,将原设计的分层综采方法改为大采高一次采全高综采。

Dayu Coal Industry Co.,Ltd.of Shanxi Jincheng Coal Group is a merger and reorganization integration project.Combining with the actual situation of the mine,the mining method is optimized.Under the premise that the production capacity of the working face remains unchanged,the mining work is simplified as far as possible,and the original design of stratified fully mechanized mining method is changed to full-mechanized mining with large mining height at one time.
