The invention belongs to the technical field of natural disasters, natural resources and environment prospecting, more particularly, to a quality control method for minor tremor positioning precision. The method comprises the following steps: marking positions according to a hypocentral location coordinate obtained from minor tremor monitoring and a measuring point coordinate; using given speed parameters and underground space structure information to obtain the travel time between the two; conducting NMO treatment on minor tremor signals to obtain a gather array after correction; taking the amplitude of sub-waves in a minor tremor before lamination as a benchmark to mark the amplitude of sub-waves after lamination. If the two are consistent, it proves that a good lamination effect has been achieved, or rather to say that a minor tremor has been precisely positioned. If not, it proves poor precision. The technical solutions of the method can effectively control the positioning precision of a minor tremor.
