摘要
为了掌握煤与瓦斯突出危险性预测过程中瓦斯压力分布规律,研究煤层瓦斯压力预测方法,为矿井瓦斯治理提供有效依据。通过分析临涣煤矿近距离突出煤层群中7#煤、9#煤的瓦斯压力分布,对不同区段瓦斯压力进行分段预测。结果表明,风化带区域与其以深区域各有不同的压力分布规律,综合考虑地温及地应力的变化对影响瓦斯压力大小的计算式,可使瓦斯压力的预测更为准确。
In order to grasp the gas pressure distribution rule in coal and gas outburst risk prediction and study the methods for predic- ting coal seam gas pressure, the paper provides an effective basis for gas control. Through analyzing the gas pressure distribution in 7# and 9^# close distanee outburst coal seam of Linhuan Coal Mine, the gas pressure are predicted in different elevation zones. The resuhs show that different regions have different pressure distribution between the weathered zone and the deep zone. More accurate predictions of gas pressure will be obtained through comprehensively considering the formula of geothermal and ground stress changes on gas pres- sure.
