摘要:准确测定煤层瓦斯压力对矿井有效而合理地制定瓦斯防治措施、预测预报煤与瓦斯突出的危险性,具有重要意义。本文介绍了煤层瓦斯压力测定中的注浆封孔工艺,分别测出了平沟煤矿的9#、10#、16#煤层的瓦斯压力,并对结果进行了分析。
Accurate determination of coalbed methane pressure is of important significance for the coal mines to take effective and reasonable measures to prevent and control gas,to predict and precast risks of coal and gas outburst.The paper described the technology for sealing grouting boreholes for determination of CBM pressure.It measured respectively the gas pressure of Nos.9,10 and 16 seams.It also analyzed the results of measurements.
