Ooze Treatment Practice for Water Drainage System of Shaft Mining for Sijiaying Iron Ore

The paper analyzes the existing problems for original-120 mhorizontal water drainage system operation and ooze cleaning of Shaft mining of Sijiaying Iron Ore.It proposes options of setting settling pond in tunnel to reduce flow rate of water to sediment ooze.By this option,the construction is easy,the operation is safety,the implementation effect is outstanding,and water drainage to surface reaching the industrial water standard.Reaches the purpose of saving resources and creating benefits,it can be popularized and applied in shaft mining production.
