Model experimental study on controlled blasting of slit charge in deep rock mass
The ground stress in deep rock masses has a significant effect on directional fracturing during slit charge blasting. In this paper, an experimental system of digital laser dynamic caustics and a static-dynamic combination loading system were used to study crack propagation behavior related to slit...
