地下金属矿山三维可视化采矿设计研究

针对传统二维采矿设计方法的缺陷,研究了改变地下金属矿山采矿设计方式的基于三维可视化模型的采矿设计新方法。根据矿山开拓系统三维模型和矿体模型在三维可视化环境下对新盘区进行设计,并建立划分后的盘区三维模型。根据实测工程模型布置采切设计巷道并绘制出中心线,通过巷道建模方法建立600-40-I盘区采切工程模型。以600-40-I盘区采切模型和矿体模型为基础,根据爆破参数完成盘区的切割槽和矿房扇形中深孔设计,建立爆破模型计算爆破量。结果表明三维可视化的采矿设计能快速地确定巷道工程的位置,缩短了设计周期,提高了设计的准确度。

Research on 3 D Visual Mining Design for Underground Metal Mine

In view of the defects of traditional way of 2D mining design,a new way of mining design based on 3D visual models is proposed to reform the mining design for underground metal mine. The new panel design is made designed in 3D vis-ual environment according to the 3D mine development model and orebody model,and then the panel model is established. The mining and cutting design roadways and their center lines are designed based on the actual measured engineering model,the mining and cutting design engineering model of 600-40-I panel is established by using roadway modeling method. Based on the 600-40-I panel model and orebody model,the cutting groove of panel and fan-shaped medium length hole of chamber are designed to establish the blasting model to calculate the blasting parameters. The results show that 3D visual mining design is good to determine the roadway engineering location rapidly and accurately,reduce the design period and enhance the design correctness.
