Research on accurate cost estimation of coal mine tunnel engineering based on BIM technology
In order to improve the accuracy of cost estimation for coal mine shaft sinking and drifting engineering,a precise cost estimation method for coal mine tunnel engineering based on BIM technol-ogy was proposed.Based on a certain project,a geological model of coal mine shaft sinking and drif-ting engineering was established using BIM technology's grid generation method and triangulation method.The spatial data of the main shaft,auxiliary shaft,and air shaft were projected to compre-hensively construct the evolution model of coal mine shaft sinking and drifting engineering.The process cost estimation data of different construction stages were obtained by analyzing the influence factors that affect the project cost and inserting them into the evolution model.The results show that the estimated cost of the method was 99.9％consistent with the actual cost,and the estimated results were accurate,which could meet the realistic demand of coal mine shaft sinking and drifting engineer-ing construction.
