摘要
煤层瓦斯压力是指瓦斯气体在煤层中所呈现的压力,是预测煤与瓦斯突出的一项重要指标。准确测出煤层瓦斯压力,进而预测瓦斯含量是有效治理瓦斯涌出异常及煤与瓦斯突出的基础。本文分析了采用注浆封孔、被动测压方法,测定金之中煤业有限公司4号、8号、9号煤层瓦斯压力,取得了满意的效果。
The gas pressure is the pressure of methane gas in the coal seam and it is an important indicator for of coal and gas outburst. Accurately measure the gas pressure and predict gas content, it is the basis for ef-fective management gas abnormal effusing and coal and pressure measuring method, determine the No. 4, 8, 9 obtains a satisfactory effect. gas outburst. This paper analyses the grouting sealing, passive coal seam gas pressure in Jinzhizhong coal Co. Ltd in Shanxi,
