Substantiation of the sequence for opencast mining of a series of flat and inclined strata using the mined-out space for internal dumps

The possibilities of using the mined-out space of opencasts for placing the overburden in internal dumps are studied. It is established that on completion of mining flat and inclined strata there are free capacities in the mined-out space consisting of 40–70% of its volume which are a resource for placing the overburden from other opencasts with substantiation of the sequence of mining large deposits. A complex criterion is suggested that takes account of energy expenditures for mining a deposit and the energy damage caused to the environment. A procedure is given for solving the problem and results are presented of calculations for the Taldinsk and the Tomusinsk deposits.
