兰尖铁矿设计采用汽车-平峒溜井-铁路联合开拓运输方案,纵向采剥法。矿山1966年开始基建,1970年2月投产。在实际生产过程中,我们根据采场不同开采时期的不同地形特点,及时地改变了采场采剥推进方向,将原设计平行矿体走向布置工作面的纵向采剥法,改变为斜交或垂直矿体走向布置工作面的横向采剥法;把三个生产水平共一个排土场,改变为每个
The design of Lanjian Iron Mine uses the car-Pingtung Chute-Rail joint development and transportation program, and the longitudinal mining method. The mine started construction in 1966 and was put into operation in February 1970. In the actual production process, according to the different terrain characteristics during different mining periods, we changed the direction of mining and stripping in time to change the vertical mining method of parallel mining body to the layout of working face into skewed or Vertical ore body to the layout of the face of the horizontal mining method; the three production levels of a total of a dump, changed to each
