摘　　要：通过对比瓦斯压力测定过程中各种封孔测压技术的优缺点,结合煤矿的实际情况,提出一种新型简易封孔测压技术,选取岩石完整的测点,避开采动裂隙构造带,利用水泥沙封前段孔,井下供水系统封堵后段孔及封堵裂隙,压风系统实现主动测压。该技术在申南凹煤矿现场进行测试,并与胶囊一压力粘液封孔测压进行对比,二者所测结果相同,但该封孔技术工艺简单,工人可操作性强,可大大缩短测压时间。By comparing the advantages and disadvantages of diiterent borenole-seaung preb- sure measuring techniques during gas pressure measurement, this paper proposed a new tech- nique, choosing complete rock measure point and keeping away from mining-induced fracture zone, that utilized cemented sand for sealing front hole, underground water supply system for sealing back end hole and fractures, and ventilation system for realizing active pressure measure- ment. This new technique was applied in situ test at Shennanao Mine, and compared with cap- sule-pressure grout sealing technique. The measurement outcomes of these two techniques were all the same, which verified that this new technique could be handled easily and reduce measuring time dramatically.
