Abstract
In view of the problem of rock burst manifestation in the 40208 return air crossheading of Xiaozhuang Coal Mine,method of theoretical analysis is adopted to analyze the main controlling factors of rock burst.The 40208 return air crossheading is evaluated to have moderate rock burst danger,and two strong rock burst danger areas and two moderate rock burst danger areas are divided.Large aperture borehole pressure and blasting pressure relief are adopted in the divided danger areas.Conduct stress monitoring within a range of not less than 200 m behind the head-on of the excavation working face,and the monitoring results show that the pressure relief measures have a good effect.关键词
