摘要
针对快速综掘工作面瓦斯易超限问题,通过分析党家河煤矿瓦斯地质规律及对106辅运巷瓦斯涌出量数据统计,得出长距离综掘工作面瓦斯涌出规律。通过理论公式计算煤壁瓦斯和落煤瓦斯涌出量与综掘面实际统计瓦斯涌出量对比,得出适合综掘面实际情况的瓦斯涌出量预测经验公式。
In the face of the problem of gas overrun in the fast fully-mechanized mining face, the gas geological law of Dangjiahe Coal Mine and the data of gas emission in 106 auxiliary transport roadway were analyzed, and the law of gas emission from long-distance full- y-mechanized mining face was obtained. At the same time, through the theoretical formula calculation, coal wall gas and coal gas emis- sion were calculated, and the results were compared with actual statistics data of the fully-mechanized face. Finally, prediction experi- ence formula of gas emission suitable for fully-mechanized face was obtained.
