摘要
为了掌握车集矿突出区域预测和防突效果检验的瓦斯含量临界值,通过研究车集矿钻屑瓦斯解吸指标Δh2和K1分别与瓦斯压力、瓦斯含量以及煤体破坏类型的关系,来分析影响钻屑瓦斯解吸指标的主要因素,以及钻屑瓦斯解吸指标与各个影响因素的定量关系,为车集矿的始突瓦斯含量临界值的选定提供理论依据。
In order to understand the critical value of the gas content for the prediction and outburst prevention effect inspection of the outburst region in Cheji Mine, with the study on the relationship of the gas desorption index △h2 and K1 of coal cuttings individually between the gas pressure, gas content and seam failure type, the paper analyzed the main factors ＇affected to the gas desorption index of coal cuttings, the quantitative relationship between the gas desorption index of coal cuttings and each influence factor in order to provide the theoretical basis to select the critical value of the initial outburst gas content in Cheji Mine.
