Based on the collection of data from questionnaires and in-depth interviews, and then by using SPSS and AMOS software, it analyzes the factors of the ecological security in coal mining areas, sets up the paths in the model, and establishes an evaluative index system for ecological security in coal mining areas. The research results prove that this model has a good emulation effect, and that it can reflect the relationship between ecological security factors. The model has good interpretive potential, and can be used in practice.
