Disaster prevention of Mining field roof fall in Open pit to underground
The research object is transformation the deep orebody ofjinning phosphate which belong to Yunnan Phosphorus Group Co from pit to underground mining.Through the mine-site field trips,on the basis of the existing mine geological occurrence conditions,proposed a stope roof fall disaster prevention technology which suitable for mining actual project overview.And related research results can provide theoretical guidance and advice of roof fall disaster for mining of Yunnan Phosphate Group or other similar conditions mines which are in transformed from open pit to underground mining.
