VentGIS是基于GDI+和GIS理论从底层开发的矿井通风可视化仿真系统,具有自动创建拓扑关系、可视化分析、通风专题图生成等功能,可进行通风系统现状诊断、模拟和分析通风系统优化与改造方案。利用VentGIS构建辛置煤矿通风仿真系统,仿真结果表明,需要更换东区主要通风机以满足其风量需求,改造南区310首采区通风系统,以减小其阻力并使其阻力分布合理。 VentGIS is a mine ventilation visualization simulation system developed from the ground up based on GDI + and GIS theory. It has the functions of automatically creating topological relations, visualization analysis and ventilation thematic map generation. It can diagnose, simulate and analyze the ventilation system optimization and transformation of ventilation system. The simulation results show that it is necessary to replace the main ventilator in the east area to meet the air volume requirement and to reform the ventilation system in the 310 first mining area in the southern area so as to reduce the resistance and make the resistance distribution reasonable.
