A method for renewal of surface of worked-out pits and caving zones includes partial filling of caving zone of pit as terraces and slopes, the upper parts of those are arranged as horizontal platforms that have inclination from center to periphery, formation of the first layer of backfill lower than the upper contour of the pit or caving zone with slopes of those left free, implementation of each next layer lower than the previous one to height of terrace, application of potentially fertile earths to horizontal plots with connection of those to each other with motor roads. The free slope of the pit that is placed than the lower layer of backfill and slopes of the terraces are covered with layer of loam. Covering with loam of slopes and terraces and free slope of the side of the pit one carries out in time interval after having filled each layer. |
