2008-3-7 · Since 1956, IOC has been blasting frozen iron ore, first in the Ferriman-Gagnon area during the period 1956 to 1964 and since 1970 in the Fleming-Timmins area (Farnam 1961 ; Lang 1966). The main problems encountered in connection with blasting in perma- frost were first, caving in of drill holes due to melting of ice during drilling.
