system of bench construction on hillslopes to produce road rights-of-way and landings whereby convex slopes are excavated and concave slopes (gullies) are filled; also, excavation of the upslope side of the right-of-way, and fill on the down slope side. (so called half-bench construction).
Earth-moving process that entails excavating part of an area and using the excavated material for adjacent embankments or fill areas.
Forestry Operations & Water Quality] Process of earth moving by excavating part of an area and using the excavated material for adjacent fill areas.
A stoping method in which the ore is excavated by successive flat or inclined slices, working upward from the level. However, after each slice is blasted down, all broken ore is removed, and the stope is filled with waste (backfill) up to within a few feet of the back before the next slice is taken out, just enough room being left between the top of the waste pile and the back of the stope to provide working space. The term cut-and-fill stoping implies a definite and characteristic sequence of operations: (1) breaking a slice of ore from the back; (2) removing the broken ore; and (3) introducing filling.
The process of earth grading by excavating part of a higher area and using the excavated material for fill to raise the surface of an adjacent lower area.
A method of stoping in which ore is removed in slices, or lifts, and then the excavation is filled with rock or other waste material (backfill), before the subsequent slice is extracted.
A technique by which the depth of a lagoon is constructed by excavation and by filling in, so that the basin is partially above and partially below ground. This reduces the potential for leaching of effluent into high water tables, but the higher berms must be more carefully constructed to ensure structural integrity.
a mining method which removes ore in horizontal slices and the remaining void is filled with waste rock before proceeding to mine the next slice of ore
