of the numerical model. Small-scale models of coal mine entry behavior may require logging geologic layers as small as 50 mm. Larger-scale coal mine models for subsidence prediction may require less logging detail. Of particular importance to note are the soft clay layers or major bedding planes with weak infilling as indicated in figure 1.
