Mine Ventilation Network Real-time Solver And Security Early Warning Systems And Implementation

Good ventilation system of a coal mine is crucial to the safe operation of the coal mine. Many coal mine accidents such as gas explosion are caused by bad ventilation. So the design of a reasonable ventilation system is a necessity for the safe operation of a coal mine. For the so many existing coal mines, careful analysis should be made to find the defects of the mine ventilation system. The existing methods for the solution of the ventilation network suffers from the shortcoming that both the data acquisition and the solution process takes too much time, so that they cannot give real-time warning of possible gas explosion.Based on the above perception, we carried out systematic research on implementation and application of real-time solution of the mine ventilation network.The main work of this dissertation is as follows:1) We first carried out systematic investigation into the mine ventilation network and network monitoring system.2) We then analyzed the existing solution model and put forward the idea for real-time solution of the mine ventilation network. It can effectively overcome the long-time delay of the existing solution methods, and realize real-time warning of security problems.3) Based on the above idea, we obtained and realized an improved optimal model for real-time solution of the mine ventilation network.4) We implemented the real-time solution algorithm of the mine ventilation network and the security warning system.5) We tested and analyzed the function and performance of this new system. Trial operations show that our solution is feasible and reliable.
