Research and Application of Coal Mine Emergency Communication Support System
Abstract：Aiming at the problems such as coal mine communication system lacking of coordination, relatively independent and do not have an unified dispatching command in case of emergency, the idea of setting up one emergency communication support system is proposed which covering coal mine by the combination of wired and wireless system. The software integration platform and the mine personnel positioning system are seamlessly linked. Based on VOIP, a variety of internet voice gateway products of different communication systems and digital full duplex speaker phone technology are developed. The communication system can achieve full coverage of mine, when an emergency happened it also can rapidly notice all underground miners in one minute with the one key function. The actual coal mine tests show that the function of this system is excellent in the emergency communication.
