The invention discloses a method and a device for compiling a strip mine mining plan in an annular propulsion mining and stripping mode. The method comprises the following steps: acquiring a mining plan target in the annular propulsion mining and stripping mode; acquiring a starting point position of annular propulsion; parameters in the mining plan target and the starting point position are input into a model, the model is a mathematical model in an annular propulsion mining and stripping mode, a multiterm function is configured in the mathematical model in advance, and the multiterm function is used for limiting different aspects of the annular propulsion mining and stripping mode; a mining plan is obtained from the output of the model. According to the method, the problem caused by manual compiling of a strip mine mining plan in an annular propulsion mining and stripping mode is solved, so that the rationality of the mining technology is improved, and the economic benefits of enterprises are ensured.
Description
technical field [0001] This application relates to the field of mining, and in particular, relates to a method and device for preparing an open-pit mining plan in a ring-propelled stripping mode. Background technique [0002] During open-pit mining, the mine is divided into multiple steps in the vertical direction, and the operations of piercing, blasting, shoveling, loading and transportation are carried out on the steps. The purpose of preparing the open-pit mining plan is to formulate a technically feasible and economically most Optimum mining stripping sequence, technically feasible includes that the advancement of each step level must meet the time-space development sequence of equipment operations, the leading relationship between the upper and lower steps must be greater than the safety platform width and the stope extension speed, economically optimal includes mining The quality of each component in the plan is within a reasonable fluctuation range, the total amount ...
