Development of the stability of coal-seam and its roof evaluation system and its application

According to the demand of the research on geology system in full-mechanized mine a mathematics-geology model for evaluation of the adapt-geological assurance system,in full mechanized mine was established which based on analysis and optimizing at the same time quantification indexes, then quantitatively analyses and evaluate the stability of coal-seam and its roof. The basic concept and technical approach for development of the system was described. By collecting a great deal of information about the mine and quantitatively evaluating the stability of coal-seam and its roof by the system, the system achieved the purpose of science calculation and the visual of the process of evaluation and analysis.
