Yao Bridge comprehensive excavation face wet coal mine ventilation and dust removal system and its application
Abstract：Based on the comprehensive excavation face wet ventilation and dust removal system principle study, after a comprehensive feasibility studies, the use of the principle of wet dust, according to the underground tunnel cross - section, the overall structure of integrated excavators, optimized design, ventilation and wet dust removal system to determine the structure, The system design, advanced technology, to achieve a dust collector, vacuum devices and piping and other components can walk with the boring machine with the machine, reducing the labor intensity, and into the ventilation duct in the pressure on the throttle with the use of The mural hairdryer, improved dust collection efficiency. Under the same conditions, do not use the system before the maximum dust concentration 310mg/m3 , with the highest concentration only after 49 mg/m3, the rate reached 84. 2% dust, dust effect is obvious, to improve the working environment of workers, improved safety ability to promote the development of integrated mechanized excavation has played an active role in creating a greater economic and social benefits.
