南芬露天矿三维可视化仿真模型及应用研究
|
摘要
本钢南芬露天矿是全国大型黑色冶金矿山之一,有几十年的开采历史,是本钢铁矿石主要生产基地之一。年剥离量为2823万吨,采矿石797.8万吨,是目前我国单体矿山年产量最高的矿山。但随着我国矿业的快速发展,传统的地测采技术分布管理模式和手工处理方式,已解决不了因矿区规模扩大、生产效率提升而带来的技术与管理难题。加快数字化和信息化建设,已经成为很多矿山企业的发展目标。
本文选择澳大利亚Surpac Minex Group开发的Surpac软件作为本钢南芬露天矿三维矿山模型建模平台,构建了数字化三维矿山模型。文中根据矿山已有的勘探线横剖面图及平面图中圈定的各地质界线圈定的矿体范围,创建了矿区的地表模型和矿体的实体模型;通过采集和录入矿区内钻孔的数据信息,建立露天矿地质数据库;创建了矿体的块体模型,并根据距离幂次反比法建立了矿体的TFe品位模型,实现了矿体的三维可视化,建成了南芬露天矿三维矿山模型数字化平台。在三维矿山模型数字模型基础上,利用大型通用有限元分析软件ANSYS采用有限元强度折减法,由Surpac三维地质模型,选择典型剖面,对矿山下部开挖的动态稳定性进行了数值模拟,得出了边坡稳定性系数随开挖的变化规律,为矿山边坡设计提供了参考依据。
本文所述理论与方法在建立大型矿山三维地质模型中,视角独特、设计新颖,且具有很强的针对性和适用性。评价结果表明数字化技术在矿床开采环境评价中是高效合理的,也将对我国矿山企业的数字化进程起到巨大的推动作用,具有重要的理论意义和实践意义。
The Bengang NaFen strip mine is one of the biggest black metallurgy mine and one of the mainly production base in china with several decades years history. The mine is the highest monomer mine in our country with Stripped volume amount as 2.823 million tonnes and exploitation amount as 7978 thousand tonnes annual. But with the fast development of the mining industry in our country, the traditional geology survey method, mining technology and the manual handling already could not solve the technical and managing problems because of the expansion of mining area scale and the promotion of productive efficiency. Speeding up the digitization and the information construction already become the development goal for many mine enterprises.
This article chooses the software Surpac development by Australia Surpac Minex Group as Bengang NaFen strip mine's 3d modeling mine construction platform and employ the digital 3d mine model. Based on the scope of ore bodies delineated by the exploration and mining of transverse section line and the various geological boundary, created the surface model and the Solid model of the ore bodies. Through collecting and inputting Drilling data within the mining area, the Bengang NaFen strip mine's geological database was build. The Article also created ore block model, and according to the inverse distance power method to establish the model of TFe ore grade and achieved a three-dimensional visualization of ore body. In Applications, using finite element analysis software ANSYS exploit finite element strength reduction, for the complexity of the slope, carried out slope stability studies, and identify multi-slip surface of landslide and to provide reference for Mine landslide control.
The theories and methods in the establishment of large-scale mining 3d geological model, unique perspectives, the design is novel, and strong applicability and pertinence. The evaluation indicates that the digital technology in environmental assessment of mining is efficient and reasonable. It also gives the digitized proceeding of mining enterprises great impetus and has important theoretical and practical significance.
