随着采矿工艺的改进、机械化水平的提高,以及开采深度的不断增加,矿山井下供风和矿井的高温问题越来越突出。矿井通风的任务,已发展为对井下环境的全面控制。笔者认为其关键在于通风系统。通风系统合理与否,对改善井下作业条件,有效地抑制矽肺病的发生,有着重要的作用。它还对能源消耗、生产成本有直接影响。 With the improvement of mining technology, the improvement of mechanization level and the continuous increase of mining depth, the problem of mine wind supply and mine high temperature becomes more and more prominent. The mine ventilation task has developed into full control of the downhole environment. The author believes that the key lies in the ventilation system. Ventilation system is reasonable or not, to improve downhole operating conditions, effectively inhibit the occurrence of silicosis, has an important role. It also has a direct impact on energy consumption and production costs.
