摘要:
针对破碎煤体顺层钻孔成孔测压困难的问题,提出了再生孔壁密封测压方法。该方法的思想是在破碎煤体中先打大直径钻孔,采用注浆法充填钻孔周边裂隙,固化孔壁煤体后,再成孔密封测压。现场应用表明:再生孔壁的密封性较好,成功实现了顺层钻孔压力的测试,钻孔压力能维持较长的时间不下降。该方法为松软煤体顺层钻孔测压提供了借鉴。
Abstract:
Aiming at the problem in difficult pressure measurement of drilling boreholes along broken coal seam, the method of sealing pressure measurement with regenerating borehole wall was presented. The large diameter borehole was drilled in broken coal, and the grouting method was used to fill the fracture around the borehole, so the coal in borehole wall was solidified. Then the borehole was drilled in solidified coal seam and sealed to measure the pressure of methane. Field application showed that the regenerating borehole had good sealing effect, the measurement of methane pressure with borehole along seam was implemented, and the pressure could maintain a long time without falling. It provides reference for pressure measurement in borehole along soft coal seam.
