Abstract: Firstly，the structure and function of atomation and early warning system of tailings dry bearch are analysised in detail.Then,the principle of automatic mnitoring and early warning of the indexs (elevation,length and slope)of tailings dry beach based on the laser measurement technology.Finally,compared with the application situation of tailings dry beach monitroing methods,the advantages of the automatic monitoring and early warning system are summarized.

Key words: Larser measurement technology, Taillings pond, Dry beach, Monitroing and early warning system
