摘要
采用X射线衍射仪和激光粒度仪分析朱集西煤矿矸石井钻井泥浆和注浆用黏土浆,显示钻井泥浆的膨胀性黏土矿物含量相对黏土浆高,且黏土颗粒粒径小;通过钻井泥浆对水泥水化历程影响的研究和由钻井泥浆配成的钻井液水泥浆的黏度、塑性强度等性能的研究,证明朱集西煤矿钻井废弃泥浆可代替黏土浆用作注浆材料。
The drilling mud of dirt shaft and clay slurry in Zhujixi Coal Mine was studied by means of XRD and laser particle analyzer.The results show that the content of smectite is higher and the partical size is smaller in drilling mud.The research of the influence of drilling mud to the hydration process of cement and the viscosity,plastic strength of drilling mud cement grout demonstrates that waste drilling mud can be used in grouting instead of clay slurry.
