Abstract

The invention discloses a coal mine dust reduction system. The coal mine dust reduction system comprises a spraying dust reduction portion, a dust collection filtering portion and a control portion. The spraying dust reduction portion comprises a hydraulic pump, a pneumatic machine, a control valve bank and an air and liquid mixer. A water source and an air source are provided through the hydraulic pump and the pneumatic machine, water and air are mixed in the air and liquid mixer, and dust in a mine is cleaned away through sprayed air and liquid mixtures. The dust collection filtering portion comprises a gas washing pool, a filter box, a fan, an exhaust manifold and a branch exhaust pipe. Gas mixtures exhausted from the mine are filtered through the filter box and washed through the gas washing pool under the action of the fan, and finally the gas mixtures are processed through ignition. The spraying dust reduction portion and the dust collection filtering portion are controlled through the control portion, and automatic processing of the system is achieved. The coal mine dust reduction system is high in working efficiency and safety, the spraying dust reduction portion and the dust collection filtering portion are controlled through the control portion to clean the mine so as to remove dust and combustible gases in the mine in time, and the environment in the mine can be safer.

Description

technical field [0001] The invention relates to the field of coal mine mining safety, in particular to a coal mine dust suppression system. Background technique [0002] At present, dust is still one of the main problems that plague coal mine production. High concentration of dust, especially respirable dust, is the direct cause of inducing pneumoconiosis among workers. Therefore, reducing the concentration of dust, especially the concentration of respirable dust is very necessary and the main technology problem. [0003] In the mining of minerals, the focus is generally placed on fully mechanized mining and tunneling working faces, while dust control between roadways is ignored. Dust may be produced at various stages of mining. During the falling process of coal, the coal dust will be suspended by the air flow in the roadway and spread in the air. In the prior art, a spray dust suppression device is used for dust reduction. The spray dust suppression device is manually op...
