一个矿山的采矿方法选择得当与否,不仅对矿山能否达产起决定作用,同时,对矿山的服务年限,经济效果等影响也很大。另外,施工管理和生产管理也不容忽视,只要那一个环节出了问题,同样都得不到预期的效果。因此,采矿工作必须是技术和管理并重。根据南京凤凰山铁矿几年来开采的经验教训,本文着重就该矿倾角45°左右厚大矿体部份探讨其采矿方法。矿山地质条件南京凤凰山铁矿属中高温热液交代充填复合型赤铁矿床。矿体走向北东,倾向北西, Whether a mine’s mining method is properly chosen or not will not only play a decisive role in whether the mine can reach production capacity, but also have a great impact on the service life and economic effect of the mine. In addition, construction management and production management can not be ignored, as long as there is a problem that part, the same are not expected results. Therefore, mining must be both technology and management. According to the experiences and lessons learned from the exploitation of Fenghuangshan iron ore in Nanjing over the past several years, this paper focuses on the mining methods for the thick ore body with a dip angle of 45 °. Geological conditions of the mine The Fenghuangshan iron mine in Nanjing is a composite hematite deposit in the middle-high temperature hydrothermal fluid. North East ore body, North West tend to,
