Coal gangue-based spherical multi-component composite material for coal mine filling and preparation method thereof
The invention provides a coal gangue-based spherical multi-component composite material for coal mine filling and a preparation method thereof, the material comprises a component A and a component B, the component A is prepared from coal gangue, clay, glutinous rice flour, a binder and water as raw materials, and the component B is prepared from a cementing material, a retarder, lime and water as raw materials. Two traditional filling materials of coal gangue and clay are granulated and then filled, a traditional powder filling mode is abandoned, conveying of filling aggregate is promoted through low friction force and good fluidity of the materials after balling, meanwhile, cement paste and the aggregate are separately filled, and the filling efficiency is improved. Pipeline blockage caused by aggregate accumulation or local condensation is fully avoided, and the pipeline is easier to repair and dredge due to branch pipeline operation.
本发明提供了一种煤矿充填用煤矸石基球型多元复合材料及其制备方法，该材料包括A组份和B组份，A组份以煤矸石、粘土、糯米粉、粘结剂和水为原料制成，B组份以胶凝材料、缓凝剂、石灰和水为原料制成。本发明将煤矸石、粘土这两种传统充填材料通过制粒后进行充填，摒弃了传统的粉末充填方式，利用材料成球后自身具有的低摩擦力和良好的流动性促进充填骨料输送，同时将水泥浆与骨料分开充填，充分避免了骨料堆积或局部凝结造成的管路堵塞，分管路操作更易修复、疏通局部堵塞。
