Problems solved by technology

With the mining of coal mines, coal gangue piles up into mountains, which not only occupy the land, but also pollute the air or cause fires by spontaneous combustion; while the traditional solid waste coal treatment process cannot completely solve the problem

Abstract

The invention discloses a comprehensive utilization and treatment process for solid waste coal. The comprehensive utilization and treatment process comprises the following specific steps of S1, pretreatment and transformation of a gangue hill; and S2, arrangement of a spraying facility. The invention provides a comprehensive utilization and treatment process for the solid waste coal. According to the comprehensive utilization and treatment process, firstly, transforming is carried out on an original coal gangue hill to form a terrace type coal gangue hill structure, so that spray water permeates and flows downwards from the top of the coal gangue hill; the entire gangue hill is covered and wetted, and therefore on one hand, the gangue hill is softened to facilitate excavation, and on the other hand, dust raising is inhibited, the temperature is reduced, and spontaneous combustion is avoided; in addition, a drainage guide ditch and a spraying system are correspondingly arranged, and thererfore water circulation spraying is achieved, resources are saved, energy is saved, and the environment is protected; and according to the process, jigging and flotation are carried out on dug and crushed coal gangue particles, high-quality coal particles are filtered out, full utilization is carried out on coal mine waste resources, and therefore the resources are further saved, energy is saved, and the environment is protected; and according to the process, treatment is carried out on the residues, so that complete utilization of the materials of the coal gangue is achieved, the pollution problem of coal gangue pile materials is thoroughly solved, and energy conservation and environmental protection are achieved.

Description

technical field [0001] The invention relates to the technical field of solid waste coal treatment and comprehensive utilization, in particular to a solid waste coal comprehensive utilization treatment process. Background technique [0002] Coal gangue is solid waste discharged during the coal mining process and coal washing process. It is a black-gray rock with low carbon content and harder than coal that is associated with coal seams during the coal formation process. Including the excavation gangue during the roadway excavation, the gangue extracted from the roof, floor and interlayer during the mining process, and the gangue picked out during the coal washing process. Coal-associated waste rock is a kind of mining solid waste, which is solid waste discharged during the process of excavation, mining and coal washing. It is a kind of solid waste in the mining industry, including gangue washing in coal washing plants, hand-selected gangue in coal production, coal and rock d...
