A New Mining Scheme For Hangingwall Ore

A new mining scheme by employing the induced caving mining method to exploit hangingwall orebody during the transition from open pit to underground mining is proposed the basic idea is to use the minedout area generated by the planned mining of the hangingwall orebody to absorb the collapsed slope body so as to avoid the influence of the innerslope mining to the normal openpit mining
