Research and Application on Prevention and Treatment Technology of Deep Mine Disaster Based on Its Dynamic Property
CAO Jian-jun
Abstract：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 de-velopment process,the deep mine dynamic disasters attribute 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 forward,which was applicated in No. 111303 first coal min-ing face in Kouzidong 1 000 m deep shaft.The effect of engineering application showed that regional measure of static pressure water injec-tion 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 lo-cal measures were taken,such as increasing support to strengthen,controlling mining speed,increasing the two lane fore poling distance and intensity,and so on.The dynamic disaster was effectively prevented.
