摘要
为保障矿山井下工作人员的身心健康和矿山的正常生产,基于矿井通风系统(VS)的重要性,设计和开发出一套可视、实用性强、准确性好的三维仿真矿井通风网络优化系统(3D VS)。该系统采用节点风压法结合Hardy-Cross迭代算法,进行矿井通风网络解算,并利用SolidWorks软件实现矿井通风系统三维仿真。以国内某大型复杂矿山为例,通过采集和调整所需数据,建立一个合理的数据库,掌握井下各主要巷道的通风状态,模拟在自然风压、添加风机或新掘进井巷等对整个矿井通风系统的影响过程。实例应用表明,运用节点风压法结合Hardy-Cross迭代算法的网络解算模块模拟井下风流状态,结果与实际情况基本相符。
To make sure the health of underground mine workers and normal production of the mine, a visible, reliable and practicable mine ventilation network simulation and optimization system was designed and developed through research of mine ventilation network calculation model and study of simulation, due to importance of mine VS. In this system, the method of node ventilation pressure combined with Hardy- Cross iterative algorithm is used to calculate the mine ventilation network, and three-dimensional simula- tion of mine VS developed by SolidWorks. Based on collection and adjustment of required data, an proper data was created, and simulated by example which can grasp ventilation state of every main downhole, and imitate influence of entire mine VS in case of natural pressure or changing fan and drifting. The simulated results show that application of network calculation module of the method of node ventilation pressure com- bined with Hardy-Cross iterative algorithm contributes to effective simulation of mine airflow state, which basically conforms to the fact.
