Practice of Optimizing and Transforming the Comprehensive Dust Prevention System in Mining Face
In view of the actual situation of the existing dust prevention technology in the mining face of Daping Coal Industry,the comprehensive dust prevention system was reformed from the aspects of external spray,transfer spray,water curtain and water quality filter,and field tests were carried out at 3111 fully mechanized mining face and 3113 transportation gateway heading face.Through the comparison of actual application effects,the dust suppression effect of the dust prevention facilities after transformation was at least 70%higher than that before transformation,effectively reducing the dust concentration at various underground work locations,creating a good working environment for on-site workers,and also avoiding the danger of explosions caused by dust accumulation.
