Head Tsarikovski Vladimir Valentinovich, Registration Date 23-05-2006 Organization State enterprise "Scientific-research mining institute" popup.description2 There are developed two variants of level-caving system and level-room system of mining reserves outside the hangingwall band. From comparison it follows that the system of level-caving is preferable as it has better factors of extraction - losses in 1,7-1,8, dilution - 1,1, cost - 1,05-1,10 times lower than for level-room one. Here is developed and offered the scheme of control. Product Description popup.authors popup.nrat_date 2020-04-02 Close
