Abstract: | An analysis is performed into the currently applied coal mining methods using mined-out space in an open pit, with describing their basic advantages and disadvantages. The urgency of further development and wider application of the gritwise-and-capwise methods that involve differently directed advance of a mining front and mined-out space utilized to the limit for overburden storage is pointed out. __________ Translated from Fiziko-Tekhnicheskie Problemy Razrabotki Poleznykh Iskopaemykh, No. 6, pp. 111–118, November–December, 2006. |
