Reciprocating to the installation of the coal bunker under mouth, in mine production, setting of a certain capacity of the coal bunker for ensuring consumer-Pinggu and high-yield, high-efficiency is very necessary. It can be effective in improving the face of mining equipment utilization, and give full play to the potential of the transport system to ensure continuous production balanced. However, the coal bunker channeling warehouses in China coal mine accidents occur frequently. only Huaibei Mining Group owned the mine will annually dozen or even several dozens of warehouses with channeling the accident occurred. Channeling warehouse accidents often caused serious damage to equipment, downhole production, warehouse when channeling coal volumes, but also blocked roadway, Transport roadway caused poor ventilation caused the gas explosion accident. To avoid channeling warehouse, developed a warehouse with anti-channeling devices to the reciprocating coal, alternative to the current use of coal, protect transportation systems and loading system to normal in an orderly fashion, allowing the system to link all coordinated.
Development of anti-channeling devices warehouses The ultimate aim is to control the gate to the coal machine, it can be made at the time of channeling positions very quickly to shut down, Coal reduce water flow to prevent and reduce channeling warehouses caused by the personal safety of the transport system and the harm. To this end, anti-channeling devices warehouse should satisfy two working state, first, to the coal normal working hours to control the location of the gate, to achieve the right to coal to the volume of coal and control bunker with water right channeling warehouse accident prevention; two warehouses in channeling at the time immediately detect and control the anti-channeling devices warehouse closure of the gates fast, effective channeling warehouse control, can be properly adjusted gate opening, the store coal by water must flow control discharges. Anti-channeling devices from warehouses powertrain and mechanical implementation bodies, their performance requirements in the normal working hours, easy access to control anti-channeling the warehouse gate in an open position; Coal and water channeling warehouses, System requirements of a rapid response and action to prevent gas and water channeling warehouses caused severe harm. The other hand, as the coal feeder roundworm room is limited, requires anti-channeling devices warehouse structure should be simple, small size, and dynamic part of the layout to be flexible and can operate in remote control.
