摘要
凌志达矿井下水平延伸开拓方式设计中,根据矿井地质条件,地面及现有生产系统情况,确定了工业广场和井筒位置,提出了2种开拓方式,并对2种开拓方式进行了技术经济比较,选择了最佳方案,符合科矿井实际情况。
In the design of under-level extending development method in Lingzhida Mine, based on the geological condition, ground and present production system situation, the industry square and shaft locations were determined. Two development methods were proposed. After economic technology comparison of the methods, an optimum scheme which is accordant with the practical situation was chosen.
