Abstract:
      In order to obtain an economically reasonable, technically feasible and safe final boundary, based on ore body model, this paper mainly proposes geometry boundary algorithm and value boundary algorithm and studies the delineation and optimization of open-pit mine boundary. Firstly, the ore deposit data and the mining engineering factors are input into computer to establish ore body model. According to anisotropy property of the rock, the final slope angles are divided into different districts, which further determine the data structure of different districts. Then, the algorithm can be implemented by the computer which can do geometric boundary and value boundary algorithm to obtain the optimal boundary. At last, the actual data of the open-pit mine is compared with the theoretical data, and boundary analysis is implemented as well.
