Survey and evaluation technique for explosive earthquake and a typical instance

The contradiction between mining explosion and safety of buildings or constructions often happens along with the developing of cities and small towns and the expansion of mining area. The survey of explosion earthquake and objectively evaluating the influence on buildings and constructions are the foundation for arbitrating the contradiction and suchlike.Therefore, it is of the actual meaning of engineering and technique and the social significance. Based on the advance of vibration measure technique , this paper discusses the technical method and the evaluation criterion of measurement for explosion earthquake, and presents a typical instance using model 891Ⅱ16 vibration measure system to measure and to evaluate the explosion earthquake.
