Researching Management Of The Whole Life-Cycle Costs On Roadway Engineering Of Coalmine Construction

At present, because the full life-cycle cost management is used only in the field of construction, highways and other applications in our country, in the mega-projects, especially in the coal industry well construction stage, is not well implemented. Cause some coal projects in the construction process only consider the cost of the construction period, while ignoring the costs of operation and maintenance. The project officially put into operation cause huge future operating and maintenance costs, and sometimes even cause a lot of unnecessary economic losses, seriously affecting the coal construction management level of enterprises and economic benefits.This article in the analysis of the research results at home and abroad on the basis of the theory of the full life-cycle cost and coal mining project carried out research on stages throughout the life cycle of coal mining project cost control analysis, the formation of coal mining project life cycle cost management theoretical system, on this basis, the BP neural network, not known mathematical methods used in coal roadway project full life-cycle cost estimation, constructed of coal mining project life cycle cost estimation model.Last, Tang gong gou of coal mining engineering, for example, this article established the full life cycle cost estimation models were tested, BP neural network is used to determine the cost of the roadway construction period, unascertained mathematics applied to the roadway determine the Cost of project operation period, resulting in Tang gong gou shaft engineering life cycle cost. The case demonstrates the estimation model built on the roadway project cost is feasible, with good accuracy and applicability. Of coal mining project cost premise of the program, coal companies are based on the full life-cycle cost minimization principle to select the optimal cost of the program, provide a strong theoretical guidance of coal mining project cost, it has a learning and reference significance.
