| Zusammenfassung: | The invention discloses a prevention and control method for downhole rockburst. The method comprises the following steps that an interference reduction area is reserved between a protection area and arecovery area; an anti-interference groove which is parallel to the axis of the protection area is formed in a top plate of the interference reduction area. According to the prevention and control method for downhole rockburst, with the theory of a rockburst mechanism as a basis, with a main influence factor of downhole rockburst as a staring point, it is put forward that the construction efficiency can be effectively improved on the premise of guaranteeing the safety of downhole construction; the anti-interference groove is easy to operate, quick to implement and convenient to form; the implementation cost of the anti-interference groove is lower than that of supporting and protection only with surrounding rock. According to the prevention and control method for downhole rockburst, withthe rockburst theory as th |
