Open AccessNumerical simulation of blasting behavior of rock mass with cavity under high in-situ stress
With the shift of coal seam mining to the deep, the in-situ stress of coal and rock mass increases gradually. High ground stress can limit the generation of rock cracks caused by blasting, and blasting usually...

Open AccessResearch on rockburst prevention systems based on the attenuation law of coal and rock vibration wave energy
During the coal and rock mass fracture process, elastic properties are released and vibration waves are radiated outward. The energy attenuation characteristics of these waves can describe the cumulative damag...
