【摘要】 通过室内1:1大煤样水力割缝抽放瓦斯的实验研究,揭示了水力割缝过程中煤与瓦斯突出现象,依据煤体特性、应力状态、应力水平、水射流压力、瓦斯压力等实验结果,并结合数值模拟计算,分析了水力割缝中煤与瓦斯的突出机理。更多还原

【Abstract】 Through experimental study of hydraulic cutting seam drainage methane indoor about big coal sample , phenomenon of coal and gas burst in the process of hydraulic cutting seam is brought to light. According to the character of coal, the stress state, the stress lever, the stress pressure water-jet ,the pressure of gas etc, along with result of numerical computing ,the mechanism of coal and gas burst in the process of hydraulic cutting seam is analyzed.更多还原
