摘要
煤层瓦斯压力是预测煤与瓦斯突出的一个重要参数,故快速准确测得煤层瓦斯压力至关重要。但M-Ⅱ型瓦斯压力测定仪在测压实践中经常会出现快速测压失败的现象。鉴于此,首先根据其测定原理和步骤分析了导致快速测压失败的各种影响因素,然后提出应对措施,以保证煤矿快速测压顺利进行。
Coal seam gas pressure is an important parameter to predict coal and gas outburst,so fast and accurate manometry of coal seam is very important. But mang failed phenomenon occured in practice of M- Ⅱ gas pressure determinitor. As a result,we firstly analyzes the influence factors leading to failed fast manometry according to the measuring principle and procedure,and then proposes the corresponding measures to ensure the sucess of fast manometry of coal mine.
