Abstract

The invention relates to a strip mine boundary optimization method and system considering an ecological environment. The method comprises the following steps: determining a maximum mining range of the earth surface and final slope angles of different areas based on mining authority and rock mass stability of a mining area, and determining a maximum geometric boundary; determining an optimized realm by adopting a cone exclusion method according to the geometric maximum realm; determining an ecological footprint and an ecological cost according to the optimized realm; constructing a realm ecologicalization optimization model by taking the maximum ecological-economic comprehensive benefit as a target, taking the optimized realm ore rock quantity and land damage area as input data and taking the final slope angles of different regions as constraint conditions; and determining an ecological optimal realm by adopting an iteration method according to the realm ecologicalization optimization model. According to the method, the accuracy and comprehensiveness of determining the open-pit mine boundary are improved.

Description

technical field [0001] The invention relates to the technical field of metal open-pit mine mining, in particular to a method and system for optimizing the boundary of open-pit mines considering ecological environment. Background technique [0002] The first step in open pit planning is usually to design the optimal state. There are many algorithms for realm design, such as floating cone method, graph theory method, improved graph theory method and network flow method. In the past ten years, realm design has mainly focused on two aspects. One is to propose different optimization methods for different actual conditions. For example, Frimpong, Asa and Szymansk considered geological structure, hydrology and engineering geological conditions in the optimization of the optimal realm, and used artificial intelligence algorithms to solve them; Jalali, Ataee-pour and Shahriar Considering the uncertainty of the realm shape, it is solved by Markov stochastic process; Latorre and Golo...
