The cost control structure of metal mine vertical shaft engineering is often set as a single layer,which leads to low control efficiency and an increase in the final cost difference.Based on actual control needs and standards,an equivalent cost control target is set,and a multi-stage control form is adopted to improve the overall cost control efficiency.The cost control structure is completed,and a metal mine thousand-meter-level vertical shaft engineering cost control model based on LS-SVM is established.The cost control is achieved through the dynamic monitoring of the vertical shaft engineering and LS-SVM correction.Test results show that after 5 measurements,compared with the traditional fuzzy adaptive BP engineering cost control group and the traditional BIM engineering cost control group,the LS-SVM engineering cost control group finally controls the controllable cost difference within 30 000 yuan.This indicates that the targeted and stable cost control method has better control effects and practical value.
