摘 要: 針對地下礦山傳統(tǒng)編制生產(chǎn)計劃時存在的隨意性大、效率低、不能編制出最優(yōu)生產(chǎn)計劃的弊端,提出運用混合整數(shù)規(guī)劃法解決采場回采順序優(yōu)化問題的方法。對無底柱分段崩落法的采場回采順序進行科學系統(tǒng)的分析,以計劃周期內(nèi)貼現(xiàn)值最大化為目標函數(shù),綜合考慮邏輯、設備數(shù)量、空間順序等約束條件,構(gòu)建采場回采順序優(yōu)化的混合整數(shù)規(guī)劃模型;在MATLAB環(huán)境下采用YALMIP編寫模型語言并調(diào)用CPLEX求解器進行求解,進而得到采場回采順序的最優(yōu)布置方案。結(jié)果表明:此方法科學可行,克服傳統(tǒng)手工方法編制生產(chǎn)計劃的弊端,實現(xiàn)資源合理高效開采,對指導礦山的實際生產(chǎn)有重要的意義。

Abstract:The traditional analysis process of production schedule is random, inefficient, and the optimal production scheduling can not be arranged. The mixed integer programming method was proposed to solve the stope mining sequence optimization problem. The amount of machinery and equipment, vertical and horizontal mine-sequencing were taken as constraints, the net present value (NPV) was used as objective function of mathematical programming model, the stope mining sequence optimization model was scenically analyzed and built based on mixed integer programming method. It was solved with CPLEX, MATLAB and YALMIP for a certain Chinese iron mine. Finally, the optimal arrangement scheme of stope mining sequence was obtained. The results show that this model is scientific and feasible, and the production schedule saves costs compared to schedules manually by meeting desired production quantities more closely and reducing employee time spent on preparing schedules. It has an important significance to guide the actual production of the mine.
