摘要
根据京西侏罗纪复杂煤层赋存条件,提出了采用"缓倾斜厚煤层分层短壁耙装采煤法"对木城涧煤矿10#煤层进行开采的方案,详述了巷道布置、控顶方式和回采工艺。
On the basis of the complex occurrence conditions of the coal seams in the Jurassic strata in the west side of Beijing,the author proposes the application of ＂shortwall sliced mining with scraper loading in gently inclined thick coal seams＂ in the #10 coal seam in Muchengjian Coal Mine in the west side of Beijing.In this paper,the author also provides a detailed description of the entry arrangement,roof control plan and coal mining techniques.
