摘要
对于目前运用的测压方法大多在煤层封孔中运用挡板、木楔封堵浆液,但挡板、木楔不能够达到带压封孔的目的,对于近水平的煤层运用注浆封孔方法,如果没有带压封孔则有效封孔距离短,很难测得煤层的真实压力。提出了近水平含水煤层本煤层带压封孔方法,对于测量近水平含水煤层瓦斯压力有很重要的实践意义,运用该方法测量潞安集团司马矿1207运输巷中得到了准确的瓦斯压力。
For current baffle and wedge are mostly used to block slurry in coal seam sealing for measuring pressure,but the grouting hole sealing in nearly level of coal seam cannot achieve with pressure.If there is no effective sealing with pressure.The sealing distance is short and difficult to measure the real pressure.This paper presents a new sealing with pressure in nearly horizontal hydrous coal seam,and using this method got accurate gas pressure in Sima mine 1207 transportation lane Luan group.
