Research and Application on Prevention and Treatment Technology of Deep Mine Disaster Based on Its Dynamic Property

In order to effectively prevent deep mine dynamic disasters, according to the display form of coal and gas outburst and rock burst, the dynamic disaster property identification system was constructed on the foundation of analyzing its occurrence conditions and development process, the deep mine dynamic disasters attri bute identification system was built, the control measures of both the stress leading dynamic disaster and the stress- gas compound disaster in deep mines were put for ward, which was applicated in No.111303 first coal mining face in Kouzidong 1 000 m deep shaft. The effect of engineering application showed that regional measure of static pressure water injection was determined on the basis of reaching the drainage standard for its stress leading dynamic disaster condition. The evaluation indexes pre- pumping rate reached to 35%, desorption gas content reduced below 3 m3/t and water content increased more than 2%. The further local measures were taken, su ch as increasing support to strengthen, controlling mining speed, increasing the two lane fore poling distance and intensity, and so on. The dynamic disaster was effecti vely prevented.
