Abstract: Roadway floor heave disasters caused by advanced pressure in fully-mechanized face seriously obstruct the safe and efficient production of coal mines. We use technology of roof cutting and pressure releasing for the serious phenomenon of roadway floor heave, and use the drilling peep and displacement monitoring means to evaluate the control effect. The results show that, the technology of roof cutting and pressure releasing effectively control roadway floor heave; by roof cutting, the floor heave increases slowly, and the amount of floor heave is much smaller, which not only achieves the purpose of control roadway floor heave, but also has economic, efficient and convenient features. This method is worth learning.
