“V型”开采方式在津巴布韦大岩墙地区缓倾斜薄矿体开采中的应用

Application of V-style mining technology on gentle dip and thin orebody in the Great Dyke Area,Zimbabwe

"V型"开采方式是针对缓倾斜薄矿体提出的一种高效开采方式。文章对"V型"开采方式较为核心的开拓运输系统、通风系统及其工程布置方式进行了初步研究。针对大岩墙地区某缓倾斜薄矿体具体的开采技术条件,提出了与"V型"开采方式相适应的斜坡道和胶带斜井联合开拓运输方案、各采区及采场相对独立的棋盘式通风网络系统。"V型"开采方式可灵活选择开拓运输系统,降低基建工程量,提高企业经济效益。

V-style mining method is a kind of high efficient technology for gentle dip and thin ore bodies. The paper takes a primary research about the development, haulage and ventilation system, which are the important sub- systems of mining system. The V-style mining method with the ramp combines conveyor development and chess- board ventilation network are applied to a mine with gentle dip and thin ore body, which is located in the Great Dyke Area. If the V-style mining method is carried out, the company can reduce the capital construction volumes and im- prove the economic benefits.
