通风管理、控制和除尘技术都是采矿的关键性辅助工作,其效率对矿井产量有很大影响。主要通风装置的设计对矿井通风计划的分析,将看出风量和压力必须适合不同时候的要求。这可换算成对动力和运转时间的要求,然后,根掰通风机的特性曲线来选择什么情况下最高的动力和最长的运转时间可以获得最高的效率。在 Ventilation management, control and dedusting techniques are all critical auxiliary aspects of mining and their efficiency has a significant impact on mine production. The design of the main ventilation device Analysis of mine ventilation plan will show that the air volume and pressure must be suitable for different time requirements. This translates into a requirement for power and run time, and then the highest efficiency can be obtained by choosing the best motivation and the longest run-time under which conditions the fan curves. in
