西曲矿生产布局和产品定位分析

Analysis on the Production Distribution and Product Positioning of Xiqu Coal Mine

通过对西曲矿主采煤层4号、8号、9号煤进行合理回采与衔接、产品定位的研究,得出结论:西曲矿产品定位为11级精焦煤,采取"三队四面"生产布局比较合适。这样,既缓解了4号、9号煤衔接紧张的局面,延长了4号煤服务年限,又合理有效地利用了井下资源,提高了精煤产率。

Through analyzing the rational stoping and connecting of 4#, 8# and 9# main minable seams and the product positioning of Xiqu Coal Mine, this paper draws a conclusion that the product of Xiqu Coal Mine is positioned as 1 lth class fine cocking coal, and the production distribution of ＂three teams and four faces＂ is more suitable, which not only relieve the tense situation of the connection between 4# seam and 9# seam and lengthen the service life of 4# seam, but also make rational use of the underground resources and increase the fine coal yield.
