Mine water inrush channel plugging material and preparation method thereof
The invention discloses a mine water inrush channel plugging material and a preparation method thereof, and belongs to the technical field of mine water disaster control, the plugging material comprises, by mass, 50-70 parts of a cement base material, 20-40 parts of an auxiliary filler, 0.1-5 parts of an additive and 50-80 parts of water; the cement base material is one or more of oil well cement, sulphoaluminate cement and superfine cement; the auxiliary filler is one or more of polyurethane, epoxy resin, water glass, quartz sand, limestone powder, gypsum, silica fume and fly ash; the additive is one or more of a water reducing agent, a retarder, an early strength agent, a dispersing agent, an expanding agent, a catalyst and a defoaming agent, the raw materials are simple and easy to obtain, the price is low, the preparation is simple, the flowability is good, the groutability is strong, the water resistance is strong, and the stone strength is high, so that the problems of long curing time, high cost, poor water resistance and the like of a plugging material in the prior art are solved. And the plugging requirement on the water inrush channel in the technical field of current mine water disaster prevention and control cannot be met.
本发明公开了一种矿井突水通道封堵材料及其制备方法，属于矿井水害防治技术领域，该封堵材料以质量份数计包括50～70份水泥基料、20～40份辅助填料、0.1～5份外加剂和50～80份水；水泥基料为油井水泥、硫铝酸盐水泥和超细水泥中的一种或多种；辅助填料为聚氨酯、环氧树脂、水玻璃、石英砂、石灰石粉、石膏、硅灰和粉煤灰中的一种或多种；外加剂为减水剂、缓凝剂、早强剂、分散剂、膨胀剂、催化剂和消泡剂中的一种或多种，原料简单易取，价格低廉，制备简单，流动性好，可注性强，抗水能力强，结石强度高，解决现有技术中封堵材料由于固化时间长、成本高、抗水能力差等，无法满足当前矿井水害防治技术领域对突水通道封堵要求的问题。
