Coal-based solid waste filling paste and preparation method thereof
The embodiment of the invention discloses a coal-based solid waste filling paste and a preparation method thereof, relates to the technical field of mine filling mining, and aims to solve the problem that the flowability of materials for filling is generally poor. The coal-based solid waste filling paste comprises the following components in parts by weight: 50-55% of coal gangue, 15-20% of fly ash, 4-8% of desulfurized fly ash, 2-5% of Portland cement, 0.5-2% of sulphoaluminate cement, 5-10% of mineral powder and 14-16% of water. The method is suitable for the application scene of filling during mining.
本发明实施例公开一种煤基固废充填膏体及其制取方法，涉及矿山充填开采技术领域，为解决用于充填的物料的流动性一般较差的问题而发明。所述煤基固废充填膏体包括以下重量份的组分：煤矸石50‑55%，粉煤灰15‑20%，脱硫灰4‑8%，硅酸盐水泥2‑5%，硫铝水泥0.5‑2%，矿粉5‑10%和水14‑16%。适用于在矿山开采时进行充填的应用场景。
