In order to show whether the blasting of the molybdenum mining will produce damaging effects on the nearby tailing dam.In this paper

combined with the actual exploration data and based on static nonlinear finite element analysis

the finite element dynamic response analysis of tailing dam under the action of blasting seismic waves is performed.The displacement distribution

stress distribution and accele-ration distribution under dynamic effect are obtained and their regularities are analyzed.Furthermore

the liquefaction and stability of the tailing dam are researched utilizing experimental data.The results show that the tailing dam under adjacent action of blast seismic is secure and stable within the limits compass of blasting distance and explosive mass.What is more

the results have certain significance for blasting design

on-site mining and operation and maintenance of tailing dam.
