在工业性试验的基础上，分析了急倾斜煤层巷道放顶煤采煤法的原理及试验效果。与我国现行急倾斜煤层采煤法进行了对比，具有工艺简单、高效、采出率高，同时全风压通风，双安全出口，属正规采煤法。这种采煤方法在我国急倾斜煤层矿井中应用前景非常广阔。 On the basis of industrial experiments, the principle and test results of caving coal mining method in steep inclined seam roadway are analyzed. Compared with the current steep coal seam mining method in our country, it has the advantages of simple process, high efficiency, high recovery rate, full air pressure ventilation and double safety exit, which belongs to the regular coal mining method. This coal mining method in China’s steep coal seam prospecting is very broad.
