Foaming agent and coal gangue doped filling material and preparation method thereof
The invention provides a filling material doped with a foaming agent and coal gangue and a preparation method of the filling material, and relates to the technical field of filling materials. The filling material disclosed by the invention is prepared from the following raw materials in parts by weight: 10 to 20 parts of sodium polyacrylate, 10 to 15 parts of epoxy resin, 10 to 15 parts of guar gum, 10 to 15 parts of a foam stabilizer, 10 to 15 parts of a water reducing agent, 150 to 250 parts of coal gangue, 100 to 150 parts of water and 100 to 150 parts of fly ash. A large amount of waste coal gangue is used for filling, so that the problem of accumulation of the coal gangue can be effectively solved, the engineering filling cost is reduced, the economic benefit is improved, environmental pollution is avoided, a supporting effect is formed in a short time, surface subsidence and surrounding rock caving are effectively prevented, the filling strength is improved, and convenient conditions and safety conditions are created for a stope face; ground surface buildings are protected, large-area ground pressure activities are relieved, and a safe environment is created for mining activities.
本发明提供了一种掺杂泡沫剂和煤矸石的充填材料及其制备方法,涉及充填材料技术领域。本发明的充填材料是利用以下重量份的原料制备而成:聚丙烯酸钠10‑20份,环氧树脂10‑15份,瓜尔胶10‑15份,稳泡剂10‑15份,减水剂10‑15份,煤矸石150‑250份,水100‑150份,粉煤灰100‑150份。本发明大量使用废弃煤矸石进行充填,可有效解决煤矸石堆积问题,降低工程充填成本,提高经济效益,避免污染环境并在短时间内形成支撑作用,有效地防止地表沉陷和围岩崩落,提高充填强度,并为回采工作面而创造方便条件和安全条件,保护地表建筑物,缓和大面积地压活动,为采矿活动创造安全的环境。
