Inorganic water fixing material for mine filling and preparation method thereof
The invention belongs to the technical field of mine filling materials, and particularly relates to an inorganic water fixing material for mine filling and a preparation method of the inorganic water fixing material for mine filling, and the filling material is prepared from the following components in parts by weight: 10-20 parts of quick lime, 30-40 parts of gypsum, 40-45 parts of an iron-aluminum series active material, 2-5 parts of an exciting agent, 1-2 parts of a retarder, 1-3 parts of a compacting agent and 1-4 parts of a defoaming agent. The preparation method comprises the following steps: grinding the iron-aluminum series active material into powder by using a grinding machine, and adding the exciting agent and the defoaming agent to obtain component A powder; crushing and homogenizing quick lime and gypsum, grinding into powder by using a mill, and adding a retarder and a densifier to obtain component B powder; the filling material disclosed by the invention has the characteristics of good water fixing capacity, high early strength and adjustable and controllable curing time and strength.
本发明属于矿山充填材料技术领域，尤其涉及一种矿山充填用无机固水材料及其制备方法，所述充填材料由以下重量份的组份组成：生石灰10‑20份、石膏30‑40份、铁铝系活性材料40‑45份、激发剂2‑5份、缓凝剂1‑2份、致密剂1‑3份、消泡剂1‑4份。所属制备方法为：将铁铝系活性材料利用磨机磨成粉剂加入激发剂和消泡剂获得A组份粉料；将生石灰和石膏经过破碎、均化后利用磨机磨成粉剂，加入缓凝剂和致密剂获得B组份粉料。本发明的充填材料具有固水能力好、早期强度高、固化时间和强度可调可控的特点。
