快速测压方法在吴家峁煤矿石门揭煤施工中的应用

Fast Measuring Pressure Method Applied to the Process of Cross-cut Uncovering Coal in Wujiamao Mine

我国绝大多数矿井均是瓦斯矿井,瓦斯事故是煤矿生产中造成人员伤害最严重的事故之一。准确测定煤层瓦斯压力对矿井有效而合理地采取瓦斯防治措施,预测煤层瓦斯突出危险性从而更好保障煤矿井下安全生产,具有重要意义。本文详细介绍了快速测压方法在吴家峁煤矿井筒揭煤过程中的应用,通过快速测压方法在较短时间内测得中央回风立井揭开4煤前的瓦斯压力,为安全快速揭煤提供了有利条件。

T he vast majority of mines in China are gas mine injuries ,one of the most serious incidents caused by coal mine gas accident .T he accurate determination of coal seam gas pressure on mine effec-tively and reasonably adopt gas prevention and control measures ,so as to better predict the risk to en-sure safety in production of coal mine gas outburst ,has the vital significance .T his paper introduces the rapid method of measuring coal uncovering application in Wujiamao Mine shaft ,through the rapid manometric method in short time to test the return air shaft opened the 4 before the coal gas pressure , provide favorable conditions for the safe and fast uncovering coal.
