特厚煤层实现综放开采的可行性研究

Feasibility Study of Fully Mechanized Caving Mining of Extremely Thick Coal Seam

以山西焦煤汾西矿业集团公司新阳矿9-10-11#合并层,即下组煤南采区S1103综放工作面为例,系统地分析研究了特厚煤层综放开采的适应性、采煤工艺及回收率等关键技术问题,该技术的推广应用,对提高单产产量,加快高产高效矿井建设,以更低成本实施综合机械化放顶煤开采技术具有重要的借鉴意义。

Takes 9-10-11# merge seam of Xinyang coal mine in Fenxi mining group company of xishan xoking coal namely S1103 fully mechanized caving mining face of next coal south mining area for example,systematmatically analyses and stadies the key technical issues of applicability of fully mechanized caving mining of extremely thick coal seam,coal mining technology and recovery rate.The popularization of this technology is of great significance for speeding up the construction of high-yield efficient coal mine and re...
