摘　　要：针对松软煤层的顺层钻孔测压时易发生塌孔造成测压失败的技术难题,提出了M-Ⅱ型瓦斯压力测定仪联合套管封孔测压技术,应用该技术顺利测出了河北金牛能源股份公司葛泉煤矿1523工作面的2#煤层瓦斯压力。In view of the technical difficulties of the failure of measuring pressure caused by collapse when the pressure of the bedding drilling was measured in the soft coal seam, the technology of M - Ⅱ - type gas pressure detector joint casing sealing drilling and measuring pressure was proposed. The technology was successfully used to detect No.2 coal seam gas pressure at No. 1523 coal face in Gequan Coal Mine in Hebei Jinniu Energy Resources Co.,Ltd.
