摘要
依据长期从事矿井通风的科研实践,论述和总结了利用金属矿山井下遗弃的自然资源和人工资源的经验。所谓的遗弃资源包括废弃的人工资源和没有加以利用的自然资源。所谓废弃的人工资源即指人工开凿利用后被废弃的旧井巷、采空区等工程;所谓自然资源即指矿井通风中固有的自然风压、地温效应等资源。主要阐述了如何利用自然风压辅助主扇通风;如何利用遗弃的废旧井巷和空区通风降阻;如何利用地温预热和预冷矿井入风流,实现冬季入风井防冻和夏季井下作业面降温等经验。这些经验对矿井通风中充分合理地利用现有资源节能降耗具有重要意义。
Based on the long-time scientific research practice in mine ventilation, the authors discuss and summarize the experiences in the utilization of discarded natural resources and artificial resources in underground metal mines. The socalled discarded resources refer to the discarded artificial resources and natural resources that have not been utilized; the so-called discarded artificial resources refer to the engineering works artificially made and discarded after being utilized such as old shafts, lanes and mined-out area; and the waste natural resources here refer to the inherent natural wind pressure, geothermal effect, etc. The paper mainly presents the experiences in how to utilize the natural wind pressure as auxiliary to the main fan; how to utilize the discarded old shafts and lanes and mined-out areas for reducing the resistance in ventilation; and how to make use of the ground temperature to pre-heat or pre-cool the inlet air so as to realize the prevention of frozen air-inlet shaft in winter and the temperature drop at underground working faces in summer, which can be of important significance to a full rational utilization of the existing resource for energy saving in mine ventilation.
