摘要:

井下通风系统作为矿山八大系统之一,是安全生产的重中之重,而风机选型则是决定通风系统运行是否流畅的关键所在。针对甘肃某铅锌矿井下采空区较多,采场与开拓工程设置集中的生产特点,设计将原有的“两翼进风、中央回风”改为“中央进风、两翼回风”的中央对角式通风系统。采用Ventsim仿真软件建立矿山三维通风模型,根据不同生产中段、生产采场求解不同时期的通风阻力,从而为风机选型提供重要的理论依据。

Abstract:

As one of the eight mine systems,underground ventilation system is the top priority for safe production,while the selection of fans is the key point to determine whether the ventilation system operates smoothly.In view of the production features such as excessive underground goafs and concentrated layout of stopes and development projects in a lead-zinc mine in Gansu,the original ventilation system air inlet for two wings and air return for the center has shifted to air inlet for the center and air return for two wings central diagonal type ventilation system by design.Ventsim simulation software was used to establish a three-dimensional ventilation model,which calculated ventilation resistance of different periods based on different production levels and stopes,so as to provide an important theoretical basis for the selection of fans.
