The Automatic Creating Research Of Mine Ventilation System Topology Relation And Ventilation Network Calculation

Topology relation is the foundation of actualizing mine ventilation network calculation, wind amount adjustment and optimization. The automatic establishment of the topology relation has simplified the calculation of the mine ventilation network greatly, reduced the work load and improved the working efficiency and accuracy. The automatic establishment of the topology relation is an efficiency way of solving problem to mine ventilation network calculation. it has totally omitted the step from the ventilation system graph of the mine to the network graph, and does not need to carry on the serial number to the tunnel extreme point . This article start off from the current situation of the mine ventilation network calculation, has discussed the importance of the topology relation, structured topology data model which is suitable for the ventilation system, and has carried on essential improvement to the establishment of the traditional topology relation. To compare with the past algorithm ,it has obviously optimized codes and improved the execution efficiency of the algorithm, made it have highly efficiency and versatility. In this article the correlative algorithm of automatic establishment of the topology relation is equally suitable for similar tunnel system of automatic establishment of the topology relation. Such as the water supply pipeline system, the heating pipeline system and so on. It has certain universality and value to popularize. The main function of the mine ventilation network calculation system is using the measure of resistance of result, to carry on analysis of ventilation resistance structure, to supply data for mine ventilation system, to supply theory basis of mine ventilation network optimization design and reform.
