煤峪口矿主采煤层瓦斯压力测试与分析

煤层的瓦斯压力是矿井瓦斯基本参数之一,准确测定煤层瓦斯压力具有重要意义。测压过程主要包括:选择测定地点和测定方法、开掘钻孔、封孔以及压力的观测确定。本文通过对煤峪口煤矿的瓦斯压力测试得出了由于产量大导致绝对瓦斯涌出量大,相对量小的这类矿井直接法不能准确测出瓦斯压力,应该用间接法测得的结论。

Gas Pressure Test and Analysis of Main Coal Seams in Meiyukou Mine

The gas pressure of coal seam is one of the basic mine gas parameters, and the accurate determination of coal seam gas pressure has important significance. Manometry processes include： selecting the measurement location and method, digging drilling, sealing and determining the observed pressure. Based on the gas pressure test of Meiyukou coal mine, this paper gets a conclusions that large yields causes absolute volume of gas emission, a relatively small amount direct method of such mines can not accurately measure the gas pressure, and the indirect method should be used.
