The debris flow triggered by construction spoils of mines and major projects turns into an important natural disaster.According to the characteristics of debris flow and the requirement of its prevention and control in mines,the paper summarizes three prevention and control modes of construction spoils-induced debris flow based on some representative cases of successful prevention and control of debris flow in the history,they are:(1) the comprehensive control mode of slope stabilizing in upper reaches area,blocking in middle reaches area and draining in lower reaches area,(2) the mode of intercepting in middle reaches area and draining in lower reaches area,(3) and the mode of blocking in middle and lower reaches areas and draining in lower reaches area.
