Of rock degree study is an important problem in mining, reasonable distribution of blocks of can reduce mining cost, reduce the subsequent secondary crushing workload, greatly improve the mining efficiency. This paper heap blasting was established by applying the fractal theory, the distributions of the degree of rock mass fractal model and quantity distribution fractal model, through the field in the sieve test samples, proves the rationality of the fragmentation distribution fractal model and availability. On this basis, the use of photogrammetry method to determine the fractal dimension and fractal model to calculate the block degree distribution, realizes from photo scanning, numerical statistics, image processing, blocks of certain mass distribution to the output blocks of fractal dimension and fractal distribution model and quantity statistical fractal model curve of all process automation.
