High-strength filling material prepared from solid-liquid wastes and preparation method of high-strength filling material
The invention provides a high-strength filling material prepared from solid-liquid waste and a preparation method thereof, and relates to the technical field of coal mining, the high-strength filling material comprises the following raw materials by weight: 53-59% of filling solid waste, 4-7% of cement, 35-40% of high salinity wastewater, and 1-2% of an additive, wherein the filling solid waste comprises coal gangue particles, mineral powder and fly ash. The coal gangue and the mine water are adopted to prepare the filling material, solid waste and waste water generated in the coal mining process are utilized, the prepared filling material can be used for landfill of a coal mine goaf, local materials are used, local utilization is achieved, the treatment cost of the coal gangue and the mine water is greatly reduced, pollution of solid-liquid waste is reduced, and the economic benefit is increased. Green and sustainable development is realized, and remarkable environmental and ecological benefits are achieved.
本发明提供一种固液废弃物制备的高强度充填材料及其制备方法，涉及煤矿开采技术领域，按重量比计，所述高强度充填材料的原料包括：填充固体废弃物53％～59％、水泥4％～7％、高盐废水35％～40％、外加剂1％～2％，其中填充固体废弃物包括煤矸石颗粒、矿粉和粉煤灰。本发明采用煤矸石、矿井水制备充填材料，不仅使煤矿开采过程中产生的固废、废水得到利用，还可将制备的充填材料用于煤矿采空区的填埋，实现了就地取材、就地利用，从而大幅降低了煤矸石、矿井水的处理成本，并减少固液废弃物的污染，实现绿色可持续发展，具有显著的环境生态效益。
