Abstract
In order to solve rock burst problem of deep complicated geological condition mine, taking Fuxing No. 2 Mine as a study object. Rock burst tendency test ing results showed that the coal seam had no rock burst tendency while the roof and floor strata had weak rock burst tendency. This paper pointed out that the main infl uence factors of rock burst were angle of seam, mining technology, mining depth, structural features of roof strata, geological formation. In view of the influence factors, some measures had been taken, including reasonable arrangement of working face, pretreatment of dangerous area, stress monitoring in the process of mining, timely relieve of the danger, these measures effectively prevented the rock burst accidents.
