An underground iron mine in China has been used as a case-study to research the subsidence due to ore extraction and backfilling during open stoping operations. A 3-D discontinuum numerical model was built incorporating geologic complexities including faults and interfaces between different lithologies,and the stoping and backfilling sequence adopted from the mine plans. The stoping was carried out in two vertically stacked horizontal layers, with a total of 16 stopes. Large displacements of up to 50 cm were observed along the roof of the stopes, and a maximum surface subsidence of 22.5 cm was *** was found to eliminate subsequent displacements and subsidence. The extraction of the upper orebody was found to influence displacements in the lower orebody. Finally, a subsidence profile was constructed to show the subsidence at all locations along the length of the surface and region of influence on the surface.

Because of poor ground conditions, stoping methods of underhand headings withcemented fill were used in the Jinchuan No. 2 mine, a paste fill system was set up. In order toevaluate the reliability of the new system, investigations and trial running have been done. Morethan 20 items of modification or improvements related to paste preparation subsystem, pump and pipesubsystem, auto-controlling and monitoring subsystem were finished. The reliability of the pastefill system was analyzed by using the theory of large complex system, and it is useful inreliability study on paste fill system.

The upper part of the Fujia deposit was mined out by open-pit, and the lower part is being mined underground. The level pillar between open-pit and underground mine had a thickness of 24 m, a length of 300 m and a maximum width of 35 in. As the level pillar contained about 5.2 million ton ore of high nickel grade, it was necessary to recover the level pillar. Because of special need of safety, underhand heading cut-and-fill stoping method was used. For the first two layers of heading, the cemented fill materials were a mix of water and high-aluminum-content cement with silicate gelling agent; and for other heading layers, total tailings was added into the fill mix in order to reduce the cement consumption. Finally, the level pillar was recovered successfully.

针对制约三维CAD用于矿山的主要原因有:数据采集烦琐、建模技术要求高、难于反复修改。为了克服这些问题,开发了矿山特征库,由其负责生成及修改特征,矿山技术人员只需要输入如三心拱巷道的宽度等基本数据即可,特征之间的关系通过矿山约束管理器控制,当主井的位置修改后不仅井口标高不用去担心,而且与其有约束关系的主运输平巷会自动跟着改变。使得采矿技术人员可以很方便地在三维数字矿山模型上直接进行巷道设计、采场设计、炮孔布置等采矿设计。该成果对于推动采矿CAD向三维的发展具有很大意义。
