Analysis on Features as Well as Prevention and Control Technology of Mine Strata Pressure Bumping in China

In order to analyze the occurred situations and the prevention and control status of the mine strata pressure bumping in China,the paper had the statistics on the occurred areas,conditions,features of the mine strata pressure bumping in China as well as the prevention and control means and effect.The paper held that with the mining depth is getting deep and deep in China,the mine pressure bumping disaster would be more and more serious.The hard thick roof condition,the fault and fold and other structures would be the main geological factors to the mine pressure bumping occurred.The coal pillar stress concentrated and dynamic load caused by the coal mining operation would be the main mining technical factors to the mine pressure bumping occurred.The paper proposed that the physical exploration method could be applied to quantify the influences of the geological structure factors.In consideration of the mine gas affected to the mine strata pressure bumping under the deep mine condition,the paper had a study on the comprehensive processing method of the multi source data for the monitoring and measuring of the mine strata pressure bumping and a study on the mine pressure bumping prevention and mining design method and the mine roadway pressure bumping capacity.
