Embodiment Construction

[0014] to combine figure 1 and figure 2 , a mine roadway dust environment control simulation test system, including simulated roadway 23, ventilation system 21, dust generation system 26, temperature and humidity control system 25, water supply and drainage system and dust removal system 24, 29, signal detection system 22 and computer control and data analysis systems27,28. The main body wall of the simulated roadway 23 adopts a multi-layer structure, wherein the inner and outer layers are made of metal materials such as stainless steel, the middle layer is an insulation layer, and the insulation layer adopts high-aluminum needle-punched blankets. An observation window 9 is provided, and the observation window 9 is made of transparent double-layer insulating glass. In order to facilitate operation, a support frame 16 is used to support the main body of the simulated roadway, so that the entire simulated roadway is 1m above the ground. The ventilation system 21 includes an a...

Abstract

The invention discloses a simulation experimental system for controlling a mine tunnel dust environment, which comprises a simulation tunnel, a ventilation system, a dust generating system, a temperature and humidity controlling system, a water supplying and draining system, a dust removing system, a signal detecting system, and a computer controlling and data analyzing system, wherein the simulation tunnel is connected with the ventilation system, the dust generating system and the temperature and humidity controlling system in the tunnel to simulate the temperature, humidity, wind speed, air pressure and dust concentration parameters in the mine, and is connected with the water supplying and draining system and the dust removing system to spray and remove dust passing through the tunnel. The signal detecting system provides related data information for the computer controlling and data analyzing system. The simulation experimental system is similar to a DC-blowing-type wind channel in a small-scale mine environment. An area in which air flows uniformly is created in the tunnel. By using the demarcated flow field, various scientific research activities related to mine dust detection, dust prevention, and the like can be performed.

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...
