Through comparative analysis on the effects of common mine-used high-strength ring chain and hot-dip zinc chain adopted in 5210 coalface and 5208 coalface respectively in Wangzhuang Coal Mine,this paper proves that the application effect of hot-dip zinc chain is good,which can avoid effectively the chain rapture accident.
