| The coal production has brought about an increasing pressure derived from the present conventional coal construction project (CCP for short) that has fostered a series of problems upon the resource, environment and society, and will undermine the prospective social and economic development, while the assessment system of the conventional CCP cannot handle the problems effectively. Thus, it is of urgency to establish a new assessment system of rational development for the CCP to evaluate and instruct in a scientific way the implement of the CCP to achieve a sustainable development in resources, environment, economy and human progress. This thesis, on the basis of the definition and connotation of CCP, first introduced the theory of the scientific outlook on development, revealed the profound relationship between the scientific concept of development and the theory of system ideology, which, applied to the assessment of CCP, established the frame of the theory of integrative evaluation on it rationally.And, by applying the theory of ecology, pointed out that the system of the CCP would be like a compound ecological system made up of man and nature, from which the author proposed the development system of CCP by Symbiosis Theory; From the analyses upon CCP by such complex theories like Dissipative Structure, Synergetics, Bifurcation Theory was put forward the conceptions of development entropy and degree in a scientific way, and was measured and evaluated of the CCP development level.The term order parameter of the rational development system of the CCP was proposed as the"system value of the rational development of CCP", from which Entropy Flow Model was constructed to drive the system of CCP into order progress and probe its evolution route.The Dynamical Model made for the development system of CCP of System Dynamics was to study the system's feedback mechanism and that respectively of resource carrying capacity, environment capacity, economic development and social progress and simulate the impact effect on the development level of CCP, thus getting the rational development mechanism, that is, the coupling effect from the four factor layers resulted in the changes within the rational development of CCP.After a full systematic study of the pollution of CCP against environment and of the violation against ecology, the author advanced the conception of life circle development and model, in which CCP course involved beginning stage, constructing stage, running stage, closing stage and ecologically recovering stage (or life circle extending stage). Considerations were taken into of rational development cost, analysis and evaluation of the effects on people's health and ecology from CCP during the course of the sustainable development, and had the calculation model of the environment evaluation of CCP life circle, resulting in the environmental index system of CCP based on PSR model.By introducing the profit and loss statement analysis on environmental economy and internalizing environmentally external cost into CCP evaluation, proposals were made to internalize negative-external impact and to add ecological-balance coefficient to the calculation formula of the designed-mining producing capacity. Thus, the whole life circle cost(LCC) of CCP included the costs of economy, environment and society and this changed the economic evaluation model of CCP.The establishment of the hierarchically structural system model of rational development evaluation and rational development evaluation index of CCP, the illustration of the connotation, calculation method, evaluation criterion of rational development evaluation index, were well demonstrated. The rational development stages of CCP involved the four below: rational development, preliminarily rational development, transition from conventional to rational development, and conventional development, which, in this paper, offered a comprehensive evaluation theory and method concerning CCP and its rational development.
