Research on System Optimization Based on Three-Dimensional Mine Ventilation Decision Platform

摘要: 针对某煤矿通风系统面临的进回风巷道风速超限、采区微风及用风地点风量紧张等问题，本文通过三维模拟方法开展系统优化研究。利用自研三维矿井通风决策平台建立仿真模型，提出北部二号回风斜井投运方案：方案I (分担一采区北部和34采区回风)通过优化通风网络分工，缩短通风路径，降低系统冗余阻力，实现北部矿井总进风量提升至24,840 m³/min，回风系统能力提高35%~40%。研究表明，方案I可均衡风量分配，缓解北部一号回风斜井压力，且主通风机运行效率达行业领先水平，为类似矿井通风系统改造提供了“阻力测定–三维建模–动态调控”的全流程技术参考。

Abstract: To address challenges in coal mine ventilation system—including excessive air velocities in intake and return airways, insufficient airflow in mining areas, and constrained air supply at usage points, the study employs a 3D simulation approach for system optimization. Using a self-developed 3D mine ventilation decision-making platform, a simulation model was established to propose an operational plan for the Northern No. 2 Return Air Inclined Shaft: Plan I (which shares return air flows from the northern section of Mining Area 1 and Mining Area 34) optimizes network distribution, shortens ventilation paths, reduces system redundant resistance, and increases total mine intake airflow to 24,840 m³/min while enhancing return air system capacity by 35%~40%. The research demonstrates that Plan I achieves balanced airflow distribution, alleviates pressure in the Northern No. 1 Return Air Inclined Shaft, and delivers main ventilator efficiency at industry-leading levels, providing a comprehensive technical reference encompassing “resistance measurement-3D modeling-dynamic regulation” for ventilation system upgrades in similar mines.
