摘要
针对矿井受压层影响,扎赉诺尔煤业公司灵北矿煤炭生产已经处于无面可采境地,提出了回采煤层与回采煤层上下滞后同采的开采方案。从矿井实际出发,通过对钻孔实见层间距、两采面顺槽实际层间距的科学计算,阐述了实现上下同采的可行性,同时对十二井六采左一片追赶距离验算结果表明:此方案技术可行,通过实践也取得显著经济效益和社会效益。
Because of the influence of the compressive layer there is no seam that can be mined in Lingbei Coal Mine of Zhalainuoer Ccoal Industry Company. In view of the actual condition of the mine, the mining scheme of simultaneously stopping coal seams with up and down lag mining method is put forward. The feasibility of realizing simultaneous extraction of up and down coal seams is expounded through scientific calculation of the actual spacing of the crossheading of the two mining faces and the seen layer spacing by boreholes. The calculation result of the pursuing distance in the left part of the 16 th stopping area of the 12 th mine＇ shaft proves that this scheme is feasible and obvious economic and social benefits are obtained through practice.
