摘要
3、 During the excavation of the main underground workshop of high-strength underground workshop (such as rock cave or rock cave), take mitigation measures to enhance stability and prevent rock explosion;Long distance muzzle limitation using fracture relaxation technique Before the excavation, a group of bullets penetrated the outside of the infrastructure, formed a bag around these bullets, and then filled with explosives and detonators. The area of rock that will be surrounded by the serious fracture of the excavation will become its protective barrier because of its limited ability to transmit the load, thus protecting the stability of the excavation in the future and preventing rock explosion.
