【摘要】：针对某大型复杂改扩建铁矿总风量不足、风流调控设施难以设置、受自然风压影响较大等问题,在对通风系统进行全面详细的调查、测定、分析基础上,从通风动力设备、通风网络、通风构筑物及通风管理等方面综合考虑,拟定了两个经济合理、技术可行、安全可靠的通风系统优化方案,并应用三维仿真通风软件对其进行模拟解算,经综合分析比较确定最佳优化方案。通过创建与之相应的智能在线动态管理模型,此模型能实现工作面风量自行诊断、量化自然风压对通风系统的影响、随通风系统的变化自动及时进行更新,为事先预防和事后决策提供可靠依据。应用结果表明,风量得到了有效、合理分配,矿井总风量由286.3 m3/s增加到429.7 m3/s,满足了安全生产的需求。
[Abstract]:In view of the shortage of total air volume in a large complex reconstruction and extension iron ore, the difficulty of setting up the air flow control facilities and the great influence of natural wind pressure, on the basis of comprehensive and detailed investigation, measurement and analysis of the ventilation system, the ventilation power equipment is considered. Considering the aspects of ventilation network, ventilation structure and ventilation management, two optimization schemes of ventilation system with reasonable economy, feasible technology, safety and reliability are proposed, and the simulation and calculation are carried out by using three-dimensional simulation ventilation software. Through comprehensive analysis and comparison, the optimal optimization scheme is determined. By establishing the corresponding intelligent on-line dynamic management model, the model can realize the self-diagnosis of the air volume in the working face and quantify the influence of the natural wind pressure on the ventilation system. With the change of ventilation system, automatic updating is carried out in time, which provides a reliable basis for pre-prevention and post-decision making. The application results show that the air volume is effectively and reasonably distributed. Total mine air volume increased from 286.3 m3 / s to 429.7 m3 / s, satisfying the need for safe production.
