[0002] At present, the dust concentration of the mine working face in my country can reach 5000 mg / m without any dust prevention measures. 3 Among the above, the proportion of mixed respirable dust is close to 40%, which has caused great threats and harm to the health of workers. At the same time, dust can cause combustion and explosion, which has brought great losses to mine production.
Even if dust removal measures are taken, the condition of most of the working faces is still quite bad, and the dust concentration has seriously exceeded the national standard

The invention discloses a mine working face simulation experiment device, which comprises a simulation roadway, underground simulation equipment, a simulation dust source, a dust removal fan, spray water supply equipment, a wind speed sensor and a dust concentration sensor. The present invention adopts the simulated roadway, and in the simulated roadway by means of underground simulation equipment, simulated dust source, dust removal fan and spray water supply equipment to simulate the air flow, dust and spray conditions of the mine working face, and then uses the wind speed sensor and the dust concentration sensor to measure the simulated roadway In order to determine the laws of wind-dust-fog migration, coupling, and settlement under different ventilation methods, the optimal parameters for ventilation and dust removal and spray dust reduction in mine working faces can be obtained, so as to scientifically and rationally arrange ventilation and spray dust removal systems. Optimum spray pressure, control wind speed to achieve the best spray effect, test the dust reduction effect of spray equipment, and provide reliable technical support for the development of efficient nozzles.
Description
technical field [0001] The invention relates to a measurement experiment device, in particular to a mine working face simulation experiment device. Background technique [0002] At present, the dust concentration of the mine working face in my country can reach 5000 mg / m without any dust prevention measures. 3 Among them, the proportion of mixed respirable dust is close to 40%, which has caused great threat and harm to the health of workers. At the same time, dust can cause combustion and explosion, which has brought great losses to mine production. Even if dust removal measures are taken, the condition of most of the working faces is still quite bad, and the dust concentration has seriously exceeded the national standard. [0003] In order to reduce the on-site dust concentration of the mine working face, my country has done a lot of research on the dust removal of the mine working face, and achieved great results. A comprehensive dust prevention technology combining venti...
