R/S analysis of gas emission in coal mine underground tunnel

摘要: 为了掌握煤与瓦斯突出危险性变化情况，分析了煤层瓦斯涌出量影响因素，采用R/S分析方法对煤矿掘进巷道瓦斯涌出情况进行研究，得出结论：掘进巷道瓦斯涌出时间序列具有分形特性，当检测到瓦斯涌出时间序列的Hurst指数出现降低趋势并有较大波动时，说明将会出现瓦斯涌出异常，需要提前采取一定的安全防范措施。Abstract: In order to grasp changes of the danger of coal and gas outburst, factors of coal seam gas emission were analyzed, R/S analysis method was used to study gas emission of coal mine tunnel, and the following conclusion was obtained: gas emission time series have fractal characteristics, when it is detected that Hurst index is decreasing and has great volatility, it indicates abnormal gas emission will occur, so certain safety precautions should be taken in advance.
