高压注浆泵对导水裂隙的封堵方案研究

Study on the Sealing Scheme of Water-Conducting Fissures by High-Pressure Grouting Pump

对井下煤岩裂隙进行注浆加固能很好地提高隔水层厚度,对煤矿防治水安全有很好的促进作用。老窑沟煤矿利用2ZGZ-120/105型高压注浆泵操作简单、注浆连续性强的特点对502机轨合一下山底板隔水层薄弱带进行加固,使岩土体成为强度高、抗渗性好、稳定性高的新结构体,以达到改善岩土体物理力学性质的目的。

Grouting reinforcement of underground coal rock fissures can well increase the thickness of the water barrier, which is a good contribution to the safety of water control in coal mines. Laoyaogou Coal Mine uses the 2ZGZ-120/105 high-pressure grouting pump with simple operation and strong grouting continuity to reinforce the weak zone of the water barrier of the 502 machine track unity downhill floor,so that the rock and soil body becomes a new structural body with high strength, good impermeability and high stability, which achieves the purpose of improving the physical and mechanical properties of the rock and soil body.
