我矿是1970年底建成投产,矿井设计生产能力60万t/年,经两次改扩建达到240万t/年。该矿井主采的二煤层为我国豫西典型的“三软”不稳定厚煤层。26041综放工作面,采用倾斜长壁采煤法俯斜开采,切巷长114m,倾斜长1032m,工作面安装72架ZFS3600-19/28D中位放顶煤液压支架,工作面两端
Mine was put into operation at the end of 1970, mine design and production capacity of 600,000 t / year, after two renovation and expansion to 2.4 million t / year. The second coal seam of the main mine is a typical “three soft” unstable thick seam in western Henan. 26041 fully mechanized coal caving face adopts inclined longwall coal mining method and the inclined mining is carried out. The length of cutting lane is 114m and the inclined length is 1032m. 72 ZFS3600-19 / 28D median caving coal hydraulic supports are installed on the working face. Both ends of the working face
