  • Numerical Modeling Procedures For Practical Coal Mine Design

    A method is presented for creating realistic numerical models for practical coal mine ground control. The method includes procedures to collect the necessary mechanical input parameters from a geologic core log, to set up a model, and to interpret calculation results. The input parameters come from a detailed geologic core log and extensive point load tests of estimate rock layer strength.
