Embodiment Construction

[0013] In the figure, the device based on the dust-isolated comprehensive dust prevention technology for fully mechanized excavation working face includes isolation room a 1, fully mechanized excavation machine 3, high-pressure water supply pump 4, water tank 5, isolation room b 2, water curtain 6, isolation room Explosive water bag 7, second transportation belt 8, rear transportation belt 9, dust concentration sensors F1 and F2, and a closed isolation room a for breathing of workers is set at 10-15 m from the front face in fully mechanized excavation roadway 10 1. Coal seam comprehensive excavator 3, high-pressure water supply pump 4 and water supply tank 5 for spraying coal powder. A dust concentration sensor F1 and a closed isolation room b 2 are installed at 45-50 m from the comprehensive excavator 3. Two or more full-section high-efficiency dust-reducing water curtains 6 with an interval of no more than 5m are set at 40-100 m behind the excavator 3 to fully isolate the h...

Abstract

The invention relates to a comprehensive dustproof technology of a fully mechanized excavation face based on dust segregation. The dustproof technology integrates a series of comprehensive dust proof measures of dust segregation, dust reduction, dust removing and the like. Firstly, coal bed high-pressure water injection is implemented to reduce the generation amount of coal dust; secondly, an excavator is utilized to perform inside and outside spray to reduce dust, and water curtain is use for performing segregation between space and space to further reduce dust; and thirdly, segregation chambers are utilized to segregate people from dust to further improve the dust reduction effect. Aimed at three aspects of mine dust sources and transmission routes and self-protection of staff, the comprehensive dustproof technology combines prevention and treatment, so that the technology is not only safe and convenient, but also can perform dustproof work systematically and comprehensively; the dust reduction effect is obvious, and the broad practicability is provided.

Description

technical field [0001] The invention relates to a comprehensive dust-proof technology for mines, in particular to a comprehensive dust-proof technology for fully mechanized excavation working faces based on isolated dust. Background technique [0002] As we all know, explosion accidents caused by mine dust occur from time to time, and mine dust has a greater degree of danger to the life and health of underground workers, and is one of the five natural disasters in coal mines. With the improvement of the degree of mechanization of coal mines, especially the widespread use of fully mechanized excavation mechanization in coal mines, the dust control work has become more and more important and urgent. Although there are some dust prevention and control measures in various mining areas, a relatively complete comprehensive mine dust prevention and control technology has not yet been formed, and the dust prevention effect is not good. affect the health and safety of workers. Con...
