Comparative Research Between Traditional Earned Value Method And Improved Earned Value Method In The Cost Control Of Coal Mine Belt Conveyor Installation Project

Most of mine construction project in the coal mining industry long duration time, geologic conditions and construction conditions and large investment in project cost control, led to changes in contract cost change the probability much higher compared to other types of projects.If control measures are not in place, it may be unable to effectively control the cost of the project.On the premise of ensuring the quality, cost control, increase coal mine construction project in economic benefits per unit of coal mine construction is an important goal, which is also trying to solve the problem.Belt conveyor is open-pit coal mining coal, stripped earth connections work best for transportation equipment, especially for large surface coal mines, has become the mining belt conveyor of coal, earth-moving implement mechatronics job stripping of cooperative operation of control equipment.Belt conveyor installation engineering construction process using earned value analysis.Project cost control, to a large extent for opencast coal mine to save money, improve efficiency, reduce coal mine equipment operation and maintenance funds.However, due to the limitations of traditional earned value, need for traditional earned value method for second-level earned value method, avoids the application of earned value method of neutron project schedule project costs associated with inconsistent progress forecast the possibility of invalid, allowing project managers to monitor and control project in a timely manner.Paper seeks to maximum and coal mine mine built engineering actual project phase combined, for coal mine mine built construction enterprise with type conveying machine installation and the other similar project provides a application improved of earned value method for cost progress control of theory method system.In same case,in the compared test traditional earned value method and improved earned value method of cost-progress performance analysis, for coal mine mine built construction Enterprise provides practical, and has can operation of project cost control of method, makes project managers can master specific subproject cost control of implementation situation.And the deviation of results targeted and specific corrective measures.Paper contribute to the promotion of coal mine construction project cost control capacity enhancements, coal mine construction project in line with the new trends in project management.
