Abstract

***The invention provides an overall optimization method and device for an open pit coal mine mining plan, a medium and equipment, and the method comprises the steps: generating a geological optimal stope sequence {C *} N in a realm region by employing a cone exclusion algorithm and taking a working slope angle as a constraint condition; calculating the raw coal mining quantity qm, t of the stope C * i (t) in the tth year; if the raw coal mining amount is smaller than the lower limit qL of the preset production capacity range and the stope serial number i (t) reaches the final limit N, namely, the preset mining plan condition is met, the net present value NPVt of the stope C * i (t) and the total net present value NPV of the feasible mining plan are calculated, and the feasible mining plan and the mining service life are stored. According to the method provided by the invention, the optimal production capacity, the mining sequence and the mining life are obtained while the optimal mining plan is constructed, so that the overall optimization of the three elements is realized, and the accuracy of the constructed global optimal mining plan is ensured.

Description

Technical field [0001] This application involves the field of open -air mining technology, especially the overall optimization method, device, medium and equipment of an open -air coal mine mining plan. Background technique [0002] After the final realm was determined, the three elements that had the greatest impact on the production benefits of open -air coal mines were production capacity, mining order, and mining life, that is, the three elements of open -air coal mine mining plan. In related technologies, a step -by -step method is usually used to determine the three elements of mining plans, that is, first determine the reasonable production capacity based on the amount of coal mining in the realm, and then determine the mining life, and finally determine the mining order that meets the established production capacity. However, the three elements of the mining plan are not independent of each other, but interactive. The optimization method of step -by -step design cannot ob...
