摘要
本文用相似材料模拟试验法，对生产实践中无法确定的顶煤回收率问题进行了研究．获得了较有价值的研究结果：单轮顺序放煤优于单轮间隔放煤方式；含矸率越高，顶煤回收率越高，无矸回收率为80％．
This paper introduced the test result of top coal mp with method of resemlesdriulate test in laboratory,the test studied on the rate of top coal mp bo has not decided inpractice .The result was that once top coal toing in order advantaged ove interval ;the higherthe rate of rock in coal,the higher the rate of top coal recovery .
