两种测压方法在贵州某煤矿的应用

Application of two Pressure Measuring Methods in Guizhou Coal Mine

贵州某矿为更好地利用自有的资源和设备进行煤层瓦斯压力测定工作,通过在同一地区施工两个试验钻孔,分别采取ACW-1瓦斯压力测定仪和水泥封孔测压法测压,开展了两种瓦斯压力测定方法主动测压法和被动测压法的对比试验,结合现场实际的需要,分析了两种测压方法的优缺点,确定了该矿测压方法的选择原则。

In order to make better use of its own resource and equipment to measure the gas pressure of seam, a coal mine in Guizhou through constructed two test drainages in the same area, taken the ACW - 1 gas pressure measuring instrument and hole sealing with cement method, carried out a contrast test between the two gas pressure measuring methods of active pressure measuring method and passive pressure measuring method, combined with the actual needs, analysised the advantages and disadvantages of the methods, de- termined the principle to choose pressure measuring method in the mine.
