More Information
Summary: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.
