Foaming reinforced filling material for coal mine and preparation method thereof
The invention relates to a foaming reinforcing filling material for a coal mine. The foaming reinforcing filling material is prepared by mixing the following raw materials in percentage by weight: 50-60% of a quick cementing material, 35-45% of an admixture, 0.1-0.25% of a concrete admixture, 0.3-1% of a stearate foam stabilizer, 1-5% of an inorganic foaming agent and 0.5-1% of a foaming activator. After water is added into the filling material, the filling material is used for goaf backfilling and underground caving goaf filling, normal-temperature foaming and curing of the filling material can be achieved, a cured body is high in strength and has certain bonding strength, and the filling material is used for coal mine safety production and goaf treatment and can provide guarantee for mine safety and efficient production.
本发明涉及一种煤矿用发泡加固充填材料，由以下重量百分含量的原料混合组成：快速胶凝材料50～60%、掺合料35～45%、砼外加剂0.1～0.25%、硬脂酸盐稳泡剂0.3～1%、无机发泡剂1～5%、发泡激发剂0.5～1%。以其加水后用于采空区回填和井下冒落空硐充填，可以实现充填材料的常温发泡固化，固化体强度高，并具有一定的粘结强度，用于煤矿安全生产和采空区治理，可为矿井安全和高效生产提供保障。
