摘　　要：煤矿井下地质条件非常复杂,煤层瓦斯压力的测定过程中经常遇到裂隙水影响瓦斯压力测定结果的情况。在长坡煤矿的瓦斯压力测定过程中,提出带压注浆封堵水源,再利用胶囊-黏液封孔,然后采用主动测压技术,快速准确的测定煤层瓦斯压力。Geological conditions were very complex in coal mine underground, and the measurement results of coal seam gas pressure were often affected by the fissure water in the process of the gas pressure determination. It proposed the methods that blocking water with pressure grouting, plugging holes with capsule - mucous and using the initiative manometry technology in the process of the deter- mination in Changpo Coal Mine, obtained the measurement results of coal seam gas pressure quickly and accurately.
