Novel mining paste filling material
The invention discloses a novel mining paste filling material in the technical field of coal mines, and is characterized in that the novel mining paste filling material comprises the following components: a base material and an additive, the base material is composed of fly ash, slag and cement, and the additive is composed of sodium chloride, sodium sulfate and a naphthalene water reducer. The fly ash accounts for 54%-62% of the total mass, the slag accounts for 26%-31% of the total mass, the cement accounts for 7%-20% of the total mass, the sodium chloride accounts for 0-0.5% of the total mass, the sodium sulfate accounts for 0-0.5% of the total mass, and the naphthalene water reducer accounts for 0.5%-1% of the total mass. The coal ash and the furnace slag are adopted as main filling materials to fill the goaf of the coal mine, the filling body strength and the production efficiency are improved, and the filling cost is reduced.
本发明公开了煤矿技术领域的一种新型矿用膏体充填材料，其特征在于：该新型矿用膏体充填材料包括如下成分：基料和添加剂，所述基料是由粉煤灰、炉渣和水泥组成，所述添加剂是由氯化钠、硫酸钠和萘系减水剂，所述粉煤灰占总质量的54％‑62％，所述炉渣占总质量的26％‑31％，所述水泥占总质量的7％‑20％，所述氯化钠占总质量的0‑0.5％，所述硫酸钠占总质量的0‑0.5％，所述萘系减水剂占总质量的0.5‑1％，本发明采用粉煤灰、炉渣作为主要充填材料对煤矿的采空区进行充填，提高充填体强度和生产效率，减少充填成本。
