Optimization of Stage Height Plan in Gently Inclined Multilayer Deposits Based on 3DMine

矿床开采阶段高度的优选研究是直接关系到矿山生产安全可靠性和经营效益的课题之一。以某多层缓倾斜矿床开拓系统为基础,首先利用3DMine矿业工程软件的三维可视化技术,构建了矿床开拓系统三维模型,实现了复杂多层矿床地下开采工程的三维可视化;其次,在常用的CAD工程设计基础上,建立了中段开拓工程多维可视、可采矿量计算、工程量核算等功能的阶段开拓工程实体模型,并展示了模型的动态剖面和透明显示效果;最后选用阶段单位掘进量最小的阶段高度优化方法,对研究矿床4个备选方案进行了优化选择。优选方案与矿山实际基本一致,验证了三维可视化的阶段高度优选方法合理可行。

Research on optimization of stage height plan in mining deposit is one of the tasks that have a direct relationship to the safety reliability and management benefit in mining production. Taking a development system of some gently inclined multilayer deposits as foundation,a 3D development system model was built first by using the 3D visualization technology of3 DMine mining software to realize the 3D visualization of the underground mining engineering of the complex multilayer deposits; Secondly,the stage development engineering entity model was built based on a CAD design,with the functions of multi-dimensional visualization of middle-section developing engineering,calculation of the mining capacity,and computation of the engineering quantities. And the models＇ dynamic section and transparency were shown as well; Lastly,the stage height optimizing plan with minimum unit stage quantities was taken to optimize the four alternative plans. The optimized plan is consistent with the actual mining,which verifies that the 3D visualization optimization of stage height is reliable and practicable.
