摘要
在梅田矿务局六矿成功地试验了巷道放顶煤采煤法，探讨了顶煤的可放性、放煤巷道的稳定性、全风压通风和提高回收率等关键问题，拓宽了放顶煤采煤法在急倾斜中厚～厚煤层中的应用。
The roadway mining of top-coal caving has been successfully practiced in No. 6 Coal Mine, Meitian Mining Administration. And the possibility of top-coal drawing. the stability of drawing roadway, the ventilation of total pressure and the raising of coal recovery are discussed. The research enlarges the application range of top-coal caving mining in steep medium to thick seams.
