| Abstract: | The mining of coal seams of the protective layer method was studied,in order to reduce high-gas coal mine gas accident during mining,based on the mechanism and feasibility analysis of upstream mining seams.Through the field practice of two coal mines Guizhou Panjiang Jinjia and the Yueliangtian,the mining gas outburst and coal dust explosion were properly solved by the use of upstream relieving mining technology,and a reasonable mining plan and applicable conditions were proposed based on the practice summa... |
