摘　　要：为了研究综放开采工艺参数与顶煤回收率的关系,以公务素煤矿1604综放工作面为背景,进行了顶煤回收率的相似模拟试验研究。研究结果表明:该综放工作面顶煤采放比在1∶2.5左右、放煤高度在6 m左右、放煤工艺采用一采一放时,顶煤回收率最好。将该工艺参数应用于工作面后顶煤混矸率有所降低,顶煤回收率有了较大幅度的提高。So as to study the relationship of process parameters and top coal recovery ratio in full mechanized caving mining, under the background of 1604 full mechanized caving face of Gongwusu coal mine, taken the study on top coal recovery ratio by similarity simulation experiment. The results showed that when the caving face top coal extraction tion. coal - caving ratio is about 1： 2.5, the caving height is about 6 m and The effect of top coal recovery ratio is best. Taking the process the caving technology is one caving one extrac- parameters into the caving face found that top mixed gangue ratio declined slightly, the top coal recovery ratio has been greatly improv.ed
