摘　　要：提出了胶囊-水泥浆-聚氨酯联合带压注浆封孔测压技术。该技术利用膨胀胶囊对钻孔初步密封,形成测压气室;在孔口用聚氨酯进一步封堵,然后在膨胀胶囊和聚氨酯封孔段之间进行带压注浆。浆液在压力作用下对钻孔周围裂隙进行填充封堵,有效防止瓦斯室内的气体通过钻孔裂隙泄漏,测压结果快速准确。Puts forward the technology of pressure measured by grouting with pressure and sealing with capsule - cement - polyurethane work together. The technology uses expansion capsules to preliminary seal for drilling, and further blocking the orifice with polyurethane, then grouting with pressure in the section of drilling between the capsule and polyurethane. Under the action of pressure, the slurry can seal the fissure surrounding a borehole to prevent gas leakage through the borehole fissure and the determination of pressure is more accurate,
