摘　　要：在综放开采过程中,顶煤采出率偏低,且顶煤破碎后,难以全面分析支架顶部的流动模式及排放特性,直接制约了对放煤技术的选择,从而阻碍了工作面回收效率的提高。针对这一问题,文章以某煤矿为例,进行顶煤放出规律研究,并确定适合工作面的放煤工艺参数,旨在提高顶煤采出率,降低含矸率。In the process of fully mechanized caving mining,the top coal recovery rate is low,and it is difficult to comprehensively analyze the flow mode and discharge characteristics of the top of the support after the top coal is broken,which directly restricts the selection of coal caving technology,thus hindering the improvement of the recovery efficiency of the working face.In view of this problem,this paper takes a coal mine as an example to study the top coal caving law and determine the caving process parameters suitable for the working face,aiming at improving the top coal recovery rate and reducing the refuse content.
