摘要
基于华亭煤业集团东峡煤矿大倾角特厚煤层赋存条件,通过对走向长壁倾斜分层综采放顶煤与水平分段综采放顶煤采煤法的技术经济比较与综合分析,认为走向长壁倾斜分层放顶煤采煤法技术较优越、更为经济合理。现场实践也取得了良好经济技术效果。
According to the occurrence conditions of steeply dipping and extra thick coal seam in Dongxia Coal Mine of Huating Coal Group, through techno-economic comparison and analysis between longwall inclined slicing and fully mechanized caving mining and horizontal section fully mechanized caving mining, the results showed that the longwall inclined slicing and fully mechanized caving mining was technically superior and economically reasonable. The filed practices had achieved favorable technical-economic effects.
