METHOD FOR UNDERGROUND MINING OF ORE DEPOSITS IN CRYOLITE ZONE |
摘要 |
FIELD: mining.SUBSTANCE: in the period of negative temperatures of ambient air from dehydrated dressing tails briquettes are pressed of ball shape with two diameters related with the following ratio:and volume of a filling material pressed in the form of briquettes of smaller diameter is determined according to the following formula:where V- total volume of solid wastes supplied for briquetting. All prepared briquettes are frozen on the surface, mixed in hoppers with vibrators, transported and placed in a mined space of cleaning units. The ratio of this space filling with briquettes with identical diameter always makes 0.523. If for filling of the mined space a set of briquettes is used in two different diameters, then the coefficient of filling of the mined space will increase to the value of 0.597.EFFECT: invention makes it possible to increase environmental safety of ore deposits mining in a cryolite zone due to increased volume of solid wastes return from dressing and higher extent of filling of the mined space by means of recovery of a permafrost massif in it.2 dwg |
