Based on the engineering examples, this paper introduces the similarity law of underground deep-hole blasting simulation and the method of deducing the actual blasting parameters from the results of model test. In the simulation experiment, it is considered that every influencing factor satisfies the similarity law and can not usually be dealt with The factors are analyzed to determine their degree of influence on the issues under consideration, to be as similar as possible to the main factors, to approximate similar unsatisfied requirements, and to ignore the less significant ones. At the same time, the experiment model of small cement mortar was designed according to the requirements of similar law of blasting simulation, and the method of making model
