根据江西和湖南两省冶金矿山的统计资料来看,冶金矿山通风经营管理上的重大问题是通风耗电量大,成本高。平均占原矿成本的6.2％,个别矿山高达12％。另外,生产实践证明。矿山自然负压可利用作为矿山通风的一种动力。小型矿山,特别是那些山区平峒开拓的中、小型矿山,自然通风起了相当重要的作用。然而,在矿山通风经营管理中,很少考虑到这一自然能源的利用。 因此,冶金矿山通风过程的科学管理对节约能源,降低产品成本是具有现实意义的。
According to the statistical data of the metallurgical mines in Jiangxi and Hunan provinces, the major problem in the operation and management of ventilation in the metallurgical mines is the large power consumption and high cost of ventilation. An average of 6.2% of the cost of ore, individual mine up to 12%. In addition, production practice proved. Mine natural negative pressure available as a power mine ventilation. Small-scale mines, especially those small and medium-sized mines that open up in the mountainous areas, play a very important role in natural ventilation. However, in mine ventilation management, few consider the use of this natural energy. Therefore, the scientific management of ventilation in metallurgical mines is of practical significance to save energy and reduce product cost.
