Study On Effective Supply Capacity Appraising Of Coal Resource In China, Based On Multi-conditions Constraint

Based on the theories and methods of resources economic, environmental economic, technical economic, mineral resources appraising, economic appraising of mineral resources, external costs internalization and system dynamic, the effective supply capacity and selecting of industry investment characteristic, conditions of development and existing issues are summarized; The factors to influence effective supply capability of coal resources in China are analyzed from the field of environmental characteristic, transport condition and developing conditions; Exploration field(coal mine field)being regard as appraising unit, the factors influencing the related variables,which are used in apprasing of the effective supply capability, are discussed, and the SD model to appraise the effective supply capability are built. Combination of coal Prediction of the Third National Report, the SD model analysis the effective supply capacity of coal resources in China concretly and empirically, Through the effective supply capacity changes with the price changes in simulation and analysis, the model is prove to be effectiveness,verify and feasibility.
