| 英文摘要: |
| Stope mining design is a very important and complicated task in daily production design and technical management of an underground mine. Based on workface technology and human-computer interaction technology, this study introduces a method of 3D parametric design for the irregular structure of stope bottoms, and focuses on solving technical problems in surface modeling of stope bottom structure. Optimization of the minimum span length algorithm (MSLA) and the shortest path search algorithm (SPSA) is conducted to solve the problem of contour-line based instant modeling of stope bottom structures, which makes possible the 3D parametric design for irregular structure of stope bottom. Implementation process and relevant methods of the proposed algorithms are also presented. Feasibility and reliability of the proposed modeling method are testified in a case study. In practice, the proposed 3D parameterization design method for irregular structure stope bottom proves to be very helpful to precise 3D parametric design. This method is capable of contributing to improved efficiency and precision of stope design, and is worthy of promotion. |
