Application of Semi-enclosed and Liquid Control Linkage Dust Control Technology in the Fully Mechanized Mining Face
SHEN Huaxiong
Abstract：During the mining process in the fully mechanized mining face,the lowering and shifting of hydraulic supports will generate a large amount of diffused dust,causing underground environmental pollution and threatening the health of miners.In view of this,it was proposed to construct a semi-enclosed dust control and drainage channel between the racks,supplemented by the use of liquid control dust removal technology.Through the design and material selection of the semi-enclosed dust control system structure between the racks,an effective semi-enclosed drainage channel was formed between the hydraulic supports,and a large amount of debris and dust were introduced into the rear chute or goaf,effectively blocking the outward diffusion of dust.The working principle and system composition of liquid control dust removal technology were analyzed,revealing how it accurately and efficiently guides and removes the generated dust.Through the reasonable combination and application of semi-enclosed dust control and liquid control dust removal technology between frames,it provides practical,feasible,efficient and reliable powder dust control technology for fully mechanized mining faces.
