Description

Technical Field

[0002] When mining in open-pit mines, the working steps are often divided into several strips for sequential mining, and each strip is called a mining belt. The design of open-pit mining belts is crucial in the planning and design of open-pit mining. The design of mining belts is not only to meet the requirements of the working space of mining equipment, but also to consider the requirements of engineering blasting parameters and mine production plans. At present, the design of mining belts is mainly based on manual interactive two-dimensional design, which has some obvious disadvantages. First, relying on manual design has subjectivity and limitations, which is easily limited by the experience and ability of designers, and it is difficult to fully consider various complex situations. Secondly, manual design is time-consuming and labor-intensive, inefficient, and cannot respond quickly to changes or adjustments in demand. In addition, omissions or errors are prone to occur, which increases subsequent corrections and costs. The above-mentioned manual interactive two-dimensional design seems to be somewhat powerless in adapting to rapid development and complex needs, and there is no effective solution in related technologies.

[0063] Exemplarily, the user opens the step line and other auxiliary design lines (if such input data exists) in the three-dimensional design view window, and determines the design range line of the mining zone by drawing or selecting through human-computer interaction.

[0064] It should be noted that the embodiments of the present application can determine the design range line of the mining belt by drawing or selecting in a human-computer interaction manner, which can enrich the method of determining the design range line of the mining belt, facilitate reducing human-computer interaction operations, and improve the level of intelligence.
