| Abstract: |
| The Daaozi ore block of Xintang iron mine’s development way is flat adit development，it’s a small mine，the scale of production for 30000 t/a．The mine originally adopted short-hole shrinkage method and sublevel caving medium-deephole exploit，with the increase of mining depth，sublevel caving medium-deephole is not suitable for the exploitation of the mine，so chooses short-hole shrinkage method and sublevel drill and benching ore removal and open stope method to mine．Through the production，the mining methods which were adopted，reduced the ore loss and dilution rate，improved the mine production safety，reduced the labor intensity，increased the economic benefit． |
