A STRUCTURAL MECHANIC ANALYTIC METHOD FOR QUANTITATIVE PREDICTION OF FAULT IN COAL MINE

The even distribution of stress field of the paleostructure is influenced by the occurrence and development of fault structures, which causes variation in joint development in coal beds. Observation of joints in fault affected belts and data obtained from the structural mechanical analysis method show that the mechanical features, type of combination and spatial distribution are controlled and affected by the mine faults of different mechanical features and scale of fault and distances between joints and faults. These leads to establishment of quantitative fault prediction model based on structural deformation coefficient. A case study is made to demonstrate the procedure of the method.
