Research on Fully Mechanized Coal Face Hydraulic Support Selection Based on the Testing Principle of Floor Specific Pressure

Abstract:

Interaction between coal face hydraulic support and floor is the crucial point for surrounding rock control in coal face and hydraulic support design optimization. Based on the principle of floor specific pressure testing, mechanized coal face hydraulic support parameters are tracked and such mechanical parameters as allowable specific pressure of floor strata are measured, in accordance with which this paper studies on the surrounding rock control in coal face and hydraulic support selection in fully mechanized coal face.
