为提高煤矿防治水注浆加固效果，改善注浆材料性能，降低注浆材料成本，同时为工业固体废弃物的高值化综合利用寻找新的途径，本文通过大量的实验室实验，最终确定了以粒化高炉矿渣为主要原材料，以脱硫石膏、水泥熟料及外加剂为辅料，研制了一种矿粉基注浆材料，通过与注浆用矿渣水泥进行交叉对比，分析矿粉基注浆材料在可流动性、相对粘度、浆液沉降速度、凝固状态及力学性质等物理性能，为矿粉基注浆材料在防治水工程中应用提供理论依据。

In order to improve the grouting reinforcement effect of water prevention and control in coal mines, improve the performance of grouting materials, reduce the cost of grouting materials, and find a new way for the high-value comprehensive utilization of industrial solid waste at the same time, through a large number of laboratory experiments, this paper finally determined to use granulated blast furnace slag as the main raw material, desulfurization gypsum, cement clinker and admixture as auxiliary materials, developed a slag-based grouting material. By cross-comparing with slag cement for grouting, the physical properties of slag-based grouting material in fluidity, relative viscosity, slurry sedimentation rate, solidification state and mechanical properties were analyzed. The study provided a theoretical basis for the application of slag-based grouting materials in water prevention and control projects.
