  • Application of a meshfree continuum method for simulation

    Understanding the caving process and material flow is fundamental to block and sublevel cave mining, and also to longwall mining in sedimentary deposits. In this paper, the application of a meshfree method, called Smoothed Particle Hydrodynamics (SPH), is demonstrated for simulating rock caving in a stratified deposit.
