摘　　要：对于当前热力推广的综采放顶煤技术,作者从科学发展观的高度,通过对大隆矿S1702工作面综采放顶和一次采全高两种采煤方式的对比试验与效益测算,说明:无论是产品质量还是企业经济效益,一次采全高方法都明显优于综采放顶方式,是在可能条件下应首选的采煤方式。Considering that the fact that of the method of fully-mechanized mining with roof caving is in prevailing now, the author took the coal seam of No.S1702 in the Dalong Mine as the example to compare the fully-mechanized mining with roof caving with the method of onetime cutting whole height. Based on the comparison and analysis it is shown that the method of one-time cutting whole height show the advantages over the other method both for the product quality and economic benefits. So, the conclusion is given that the method of one-time cutting whole height will be preferred if the conditions are possible.
