Filling chamber for gas phase fracturing equipment of underground coal mine

The invention discloses a filling chamber for gas phase fracturing equipment of an underground coal mine. The filling chamber comprises a filling area, a consumable material area, a finished product area, a weighing leakage detection area, an unused gas cylinder area and a used gas cylinder area. The filling area is provided with a gas phase fracturing equipment assembly system, a gas phase fracturing equipment filling system and a waste gas exhaust system. Driving power of the gas phase fracturing equipment assembly system and the gas phase fracturing equipment filling system is provided by underground compressed air, and waste gas generated in the filling process is connected with the waste gas exhaust system and exhausted to a main return way through a pipeline. Compared with a ground filling workshop, the filling chamber for the gas phase fracturing equipment of the underground coal mine can greatly shorten the transport time of the gas phase fracturing equipment, improve the use efficiency of the equipment, lower the labor intensity of workers, shorten the cycle time of the fracturing equipment, mitigate the problem of shortage of the gas phase fracturing equipment and greatly lower the cost.
