Study on the identification and evaluation method of natural resources value in abandoned land of open-pit coal mine

With the economic transformation and the depletion of coal resources, the secondary development and utilization of abandoned open-pit coal mines have become a new choice for resources-based cities to obtain incremental space resources.Based on scientific evaluation of resource value, this study proposed an ideal model and technical method for identifying and quantitatively evaluating the resource value of abandoned open-pit coal mines. Taking the Fushun West Open-pit Coal Mine as an example, the natural resources of this mine were demonstrated intuitively. It is evaluated that the total value of the West Open-pit Coal Mine is approximately 2.44 billion yuan, during which the direct use value accounts for 99.57%. Among the various values, the value of the tertiary industry exceeds those of the primary and secondary industries. This is also in line with the current ecological restoration and development direction of the West Open-pit Coal Mine, thereby, verifying the effectiveness of the model.
