Paste filling material for goaf, slurry and preparation method of filling body
The invention provides a paste filling material for a goaf, slurry and a preparation method of a filling body, wherein the filling material comprises the following raw materials in parts by mass: 100-140 parts of coal gangue, 60-120 parts of fly ash, 10-32 parts of cement, 20-50 parts of desulfurized gypsum and 10-50 parts of stone powder; and the mass ratio of the components of the filling material is coal gangue:fly ash:cement:desulfurized gypsum:stone powder=12:10:2.4:4:2. The paste filling material slurry comprises the following components: 100 to 140 parts of coal gangue, 60 to 120 parts of fly ash, 10 to 32 parts of cement, 20 to 50 parts of desulfurized gypsum, 10 to 50 parts of stone powder and water. According to the paste filling material for the goaf, industrial waste is used for replacing part of cement, the optimal proportion of the filling material is determined, the raw materials are wide in source and low in price, and the cost is low.
本发明提供一种用于采空区的新型膏体充填材料、浆液和充填体的制备方法，按照质量份数计，充填材料包括如下组分的原料：煤矸石100‑140份、粉煤灰60‑120份、水泥10‑32份、脱硫石膏20‑50份和石粉10‑50份；充填材料组分之间满足如下质量比，煤矸石：粉煤灰：水泥：脱硫石膏：石粉＝12:10:2.4:4:2。膏体充填材料浆液包括如下组分：煤矸石100‑140份、粉煤灰60‑120份、水泥10‑32份、脱硫石膏20‑50份、石粉10‑50份和水。本发明的用于采空区的膏体充填材料，使用工业废弃物代替部分水泥，确定了充填材料的最优配比，原料来源广泛且价格低廉，成本较低。
