Abstract:

There are two ore chute ways which include the iron hopper gravity ore chute and the vibrating drawing machine ore chute in the underground stopes in Jiaojia gold mine.For the ways，the security is not high，and the operators need more shortcoming.At the same time，properties of the ore are similar to the clay in Jiaojia gold mine, which have caused difficult problems of ore chute.For the above reasons，a new type remote control scraper-drawing machine has been designed.It solves the problem of the viscous ore blocked chute effectively，and reduces the labor intensity of the blocking.As well as，it realizes remote ore chute which is far away from ore position used the remote video technology，and improves ore chute security conditions and efficiency.

Key words: scraper-drawing machine, stope ore chute, blocking, ore security conditions
