Abstract: Coal resources provide the basic power for the development of Chinese industry and economic society, but its large-scale mining and utilization has brought a series of environmental problems. In order to solve the problem of solid waste emission and environmental pollution commonly faced by Chinese coal industry, the specific requirement of the new solid waste treatment technology was clarified by summarizing the development course and technical bottleneck of traditional technology, and the technical conception of fluidization slurry backfilling technology was put forward innovatively, its technical connotation and advantages were expounded, six core technologies of fluidization slurry treatment technology were introduced in detail, Namely: intelligent pipeline transportation technology, four-dimensional collaborative filling technology, scientific and accurate pulping technology, mining overburden drilling technology, holographic remote control technology and safety production guarantee technology. On this basis, two development directions were put forward. including underground intelligent separation + on-site slurry backfilling and intelligent slurry backfilling. The technical framework of slurry treatment of solid waste logistics in coal mine was preliminarily formed, and the actual design case was given to illustrate. The proposal of fluidization slurryfilling technology provides a new solid waste treatment method for Chinese mining enterprises, which enriches the solid waste treatment technology system of coal industry in China, and lays a foundation for the realization of green mining, clean utilization and zero waste emission of coal resources.
