摘要
洛坝铅锌矿作为一个多矿区整合矿山,地表坑口众多、巷道纵横交错、井下作业点多面广、采空区规模庞大,导致井下污风串联严重、风流紊乱,通风效果较差.通过通风线路调查、矿井需风量计算和基于Ventsim的通风网络解算,进行了针对性的多矿区整合条件下矿井通风系统整合优化方案研究,改善了井下风流治理、提高了通风效果.
Abstract
Luoba lead-zinc mine,as a multi-mining area integrated mine,has many surface openings,intersecting roadway,wide underground operation points and huge goaf scale,which lead to serious underground pollution air series,air flow disorder and poor ventilation effect.Through the investigation of ventilation line,calculation of mine air demand and calculation of ventilation network based on Ventsim,targeted research on integration optimization scheme of mine ventilation system under multi-mine integration condition is carried out,which improves the management of underground air flow and improves the ventilation effect.
