摘要
本文详细分析了煤层倾角及顶煤厚度对缓倾斜厚煤层综采放顶煤放煤工艺的影响,通过现场试验和模型实验对理论分析进行了验证,提出了合理放煤工艺及适合于放顶煤开采的煤层最小厚度的确定原则。
The effects of the dip of the seam and the thickness of the top coal on the coal caving techniques in fully mechanized top-coal-caving face in a slighty dipping have been ana- lysed in detail in this paper.The theoretical findings have been verified by site test and model experiment.The principles determining the reasonable caving techniques and the minimum seem thickness suitable to coal caving have been posed.
