The calculated results from the model were very conformable to the actual statistic results of the stope and were used to modify the blasting design of the teststope, with a satisfactory result.
A test calculation of the stope slope in Shenfu Dongsheng and Jungar coal fields by using this method gives a more safety reserve of the slope .
