Abstract

The invention discloses a method for determining a final boundary-to-boundary side slope of a strip mine, a storage medium and electronic equipment. The method comprises the following steps: acquiring a safety reserve coefficient Ks of the boundary-to-boundary side slope of a design boundary and the step number N of the boundary-to-boundary side slope; sorting the N steps in sequence; the Nth step to the (N-i) th step are combined to obtain an ith slope, the stability coefficient Fi of the ith slope is calculated, and i is larger than N and larger than or equal to 1; and when Fi-Ks is smaller than or equal to a preset difference value, taking the ith side slope as a final boundary-to-boundary side slope. Under the condition that the height difference between the earth surface and the pit bottom of the stope is not changed, the slope angle of the boundary slope is increased, the stripping amount of the final boundary is reduced, and therefore the purposes of reducing the stripping ratio and reducing the production cost are achieved.

Description

technical field [0001] The present application relates to the technical field of coal mines, in particular to a method for determining the ultimate boundary-to-boundary slope of an open-pit mine, a storage medium and electronic equipment. Background technique [0002] The ultimate state is an important part of the design parameters of the open-pit mine, which is directly related to the economic rationality of the stripping ratio of the open-pit mining area, and the shape of the boundary slope is the direct reflection of the final state in space. At present, the method to determine the final state is: under the same flat plate and step parameters as a whole, different design states are obtained with different stripping ratios as variables, and the design state corresponding to the most economical and reasonable stripping ratio is taken as the final state . In the process of implementing the present application, the inventors found that the boundary slope of the existing dete...
