Description
technical field [0001] The invention belongs to the technical field of mine safety detection, in particular to a mine dust concentration environment control simulation test system. Background technique [0002] A large amount of dust will be generated in various processes in the mine mining process, and the dust concentration is sometimes as high as 100mg / m 3 According to coal mine statistics, the number of underground workers who die of pneumoconiosis every year is about twice that of the underground workers in the same period; in addition, dust is explosive, which seriously threatens mine safety. Production. To this end, effective measures must be taken to control the diffusion and flying of dust, so that the dust concentration in the air flow of the roadway can be reduced below the safe value, so as to ensure the sanitary conditions of the underground working environment, protect the health of workers, and promote mine safety production. In terms of dust measurement met...
