The invention discloses an experiment method for simulating different types of rock explosion. The experiment method is characterized by comprising the following steps: step 1, preparing a rock explosion test sample; step 2, performing a three-direction six-side loading, single-side unloading and top gradient loading experiment method on the rock explosion test sample; step 3, choosing appropriateinitial confining pressure, loading to initial confining pressure level and then simulating a chamber excavation process through horizontal single-side unloading under the situation that load of other sides are unchanged; step 4, achieving different gradient loading purposes by controlling four groups of independent loaders at the top of the rock explosion test sample, simulating chamber tangential stress concentration and gradient loading until the rock explosion test sample is damaged; step 5, in a rock explosion test sample loading damage process, monitoring and recording an experiment process; step 6, cleansing a
