Abstract The waterproof partition coal pillars are divided into the plastic zone，the elastic core zone and the hydraulic fractured zone on the basis of the existing reasonable structural division of coal pillars. The width of the plastic zone is derived with the application of limit equilibrium theory，the parabolic strength theory and the method of separation of variables. The width of the elastic core zone is derived adopting the semi-inverse method with the consideration of mine pressure and hydraulic pressure effects and the selection of unified strength theory. The width of hydraulic fractured zone is determined considering the infiltrating and softening effects of water. The comparisons with the results from previous typical models for each zone confirm the reasonability of the model. The monitored structures of inner coal seam with the ultrasonic probing technique also verify the correctness of the model. The method was applied to the design of the waterproof partition coal pillar in Dongjiahe coal mine for the secure and high-efficient production of the coal mine.

Key words： mining engineering waterproof coal pillar hydraulic fractured zone parabolic strength theory unified strength theory(UST) ultrasonic probing
