Key Theory and Technical Analysis on Mine Pressure Bumping Prevention and Control

Based on the practice sammarization of the mine pressure bumping prevention and control in over 50 mines,the paper introduced the key theory of 13 mi ne pressure bumping control and the related technologies. The paper stated the eight important links of the risk evaluation before the coal mining operation,optimization of the mining design plan,the pre-treatment of the mine pressure bumping prevention in the risk zone before the coal mining operation,monitoring and early warning duri ng the coal mining process,danger relieving of the risk zone during the mining process,inspection of the danger relieving effect,safety management of the coal mining fa ce and prevention and control experience summarization in the completed set system of the mine pressure bumping control.The paper provided the organization syste m,technical system,management system,closed loop working process to be established in the mine pressure bumping prevention and control from a view of the practice s.A mine pressure bumping prevention technology with enhanced pressure releasing,enhanced monitoring and measuring and enhanced prevention should be conducte d in the mine pressure bumping danger zone.
