Interactive Collection and Processing Technology of Mine Ventilation Network Information

Aiming at the problems existing in collecting and treatment ventilation network information, the paper puts forward a method on the mine ventilation system diagram's combination of manual analysis and automatic identification, which can collect network information interactively and draw a simple ventilation system graph with GIS function and a network with face centralized layout in center, inlet air down and outlet air up; Associational branches are moved with the nodes. A simplified fixed Q method is used in network calculation, which is completed to meet the requirement. The result is shown in network graphs. Through in situ test, the result shows that the interactive collection means is feasible; simple ventilation system is simple and intuitive; the efficiency of drawing and editing network graphs is very high; the range of searching cotree's branches and independent loop is greatly reduced, and the velocity is improved.
