针对目前通风软件功能存在局限性的现状,结合矿山开采深度增加和通风网络越来越复杂的实际,开展了新型矿井通风系统三维可视化研究。基于回路风量法和节点风压法提出了新的改进解算算法,使其能够解决复杂的通风网络解算问题;根据新的矿井通风系统双线巷道自动生成算法逐层生成闭合轮廓线,将各层轮廓线三角化并将所有的三角化网格合并,生成封闭的三维联通实体巷道;采用“层次式平台+插件”的方法进行系统开发。最终实现了通风系统三维可视化模拟、网络解算优化、通风管理信息化;与矿山数字化软件相结合,可有效集成监控监测系统,实现数据管理一体化和矿山安全管理。

At present there are a lot of shortages in the function of ventilation software. The depth of mining is getting increased and ventilation network is more and more complicated. Therefore a new 3D visualization system of mine ventilation network was studied to solve above problems. Based on the method of circuit air-quantity and node ventilation pressure, a new improved ventilation network solution algorithm was put forward to calculate complex ventilation network. Based on a novel algorithm of double-line laneway automatic generation for mine ventilation system, closed contour was generated layer by layer, then the contours were triangulated and all the triangulated mesh was combined to generate 3D connected entitative laneway. System developing was made adopting the method of 'hierarchical platform+plug-in'. The system realized 3D visualization simulation of ventilation system, network solution optimization, ventilation management informatization. Its combination with mine digital software can effectively integrated monitoring detection system, realizing data management integration and safety management.
