Wujiagou Coal Mine Cataclysm Features And Emergency Ventilation Control With The Belt Transport System

Mine fire is one of the five coal mines disaster,with a sudden, rapid development, fire and ambulance difficulties and other characteristics.Easily disturbed, and even cause changes in the status of the entire mine ventilation with Merry affected by the fire power, Production areas would cause the spread of toxic gases after the fire broke out pollution, a great threat to the health and safety of mine workers.By establishing Merry mine fire control system, such as the use of automatic throttle to achieve remote control air flow, so that the fire smoke when the fire according to a predetermined control program is discharged through the return air wind tunnel, effectively prevented the expansion of the scope of fire smoke technology, so that the fire is the scope of the damage is limited to the minimum range, and provide guidance for escape disaster prevention personnel, personnel of reducing the casualty rate has great practical significance.In this thesis, the actual situation in Golden Ocean Group's five coal mine belt transport system Ravine, made a series of belt transport related research period features and emergency fire lane Merry control, given the need for coal mine production safety, mine commissioned five Ravine Liaoning technical University with a corresponding transformation of its belt transport system, the position of the belt transport system install emergency Merry throttle control systems, windscreens and sensors, install the number described in detail and on the basis of numerical simulation, the establishment of a coal mine belt transport system during a fire emergency plan to control air flow system, air flow conditions during simulated fire damper control after making comparison with the actual situation, to prove the feasibility of its programs.
