Blasting fragmentation distribution is an important index adopted generally to evaluate the quality quantitatively in engineering . It affects the efficiency of each follow-up producing process and the total cost in mining .In building dam engineering with blasting, the blasting fragment-size has a principal influence on the dam quality. The problem to control the blasting fragmentation was very complicated. In despite of plentiful study done by researchers at home and abroad, the question was not solved ve...
