High-water filling material for mine filling and construction application method thereof
The invention discloses a high-water filling material for mine filling and a construction application method thereof, the powder material of the high-water filling material comprises ordinary Portland cement, a magnesium oxide expanding agent, slag powder, industrial gypsum powder and an activation wake-up agent, and the activation wake-up agent is composed of metaaluminate, silicate, fluoroaluminate, acrylic acid and a catalyst. The invention relates to a construction application method of a high-water filling material for mine filling. The construction application method comprises the following steps: sequentially weighing powder materials of the high-water filling material and uniformly mixing; and weighing water according to requirements on a construction site, adding the water into the powder material, stirring for 2 minutes by adopting a forced stirrer, and uniformly stirring to obtain the high-water filling material for mine engineering. According to the filling and supporting requirements of mine engineering, the high-water filling material is injected into an exploited mining area, after the high-water filling material is condensed and solidified, the filling and supporting requirements of the exploited mining area are met, and the high-water filling material for the mine engineering is large in fluidity and long in retention time.
本发明公开了一种矿山充填用高水充填材料及其施工应用方法，其粉体材料包括普通硅酸盐水泥、氧化镁膨胀剂、矿渣粉、工业石膏粉、活化唤醒剂，活化唤醒剂由偏铝酸盐、硅酸盐、氟铝酸盐、丙烯酸、催化剂组成，矿山充填用高水充填材料的施工应用方法，将高水充填材料的粉体材料依次称量并混合均匀；在施工现场按要求称量水，加入粉体材料中，采用强制式搅拌机搅拌2min，搅拌均匀即得矿山工程用高水充填材料；根据矿山工程充填支护需求，将高水充填材料注入已开采矿区，待其凝结固化之后，即完成对开采矿区的充填支护需求，本发明提供的矿山工程用高水充填材料流动性大、保持时间长。
