摘要
为解决浅埋坚硬特厚煤层综放采出率低的问题,论文在系统分析综放开采煤炭损失组成的基础上,从工作面设备选型、回采巷道布置、采放工艺优化等方面研究了提高综放采出率的技术措施,并首次使用回煤箱减少放煤损失。研究成果在俄霍布拉克煤矿得到成功应用,工作面采出率达84%,可为类似条件下的煤层综放开采提供参考。
In order to improve the low mining rate of fully mechanized top coal caving in shallow hard thick coal seams, this paper, based on systematic analysis of coal loss composition in fully mechanized top coal caving face, researches the technical measures in improving mining rate in fully mechanized top coal caving face from equipment selection, mining roadway layout, caving technology optimization, and other aspects. Recovery coal box is firstly adopted to reduce the coal caving loss. The research results have been successfully applied in Ehuobulak Mine with the working face mining rate of 84%, which can provide a reference for fully mechanized top coal caving in similar conditions.
