摘要
为进一步改进胶囊封孔在实际测压中的应用效果,利用MⅡ型瓦斯压力测定仪技术在金星煤矿对将要揭露的石门周围进行原始压力测定,与水泥砂浆封孔测压进行了对比,对测定结果进行了总结分析,并对MⅡ型瓦斯压力测定仪进行了优化建议。
In order to improve the capsule-sealing effect during the pressure measurement,M Ⅱ-type gas pressure measuring instrument was used to determine the initial gas pressure a-round the cross-cut before opening the seam. The measurement result obtained by capsule-sealingwas compared with that by grouting mortar sealing. Based on the analysis of the measurement re-sults, some advice were proposed for the improvement of M Ⅱ-type gas pressure measuring in-strument.
