The invention relates to mining and can be used for open development of mineral deposits.

The known method of dumping on an inclined base, including the dumping of rocks tiers of the blade in two stages: first on the prism lock to horizon, which is defined by the boundary between the prism lock and prism active pressure, then filling tiers of the blade of the second stage above the horizon (USSR Author's certificate 1247537, the Method of forming upland dumps, IPC IS 41/00, publ. 1986).

The disadvantage of this method is the reduction of the margin of stability of a slope in the construction of the blade on the prism of active pressure, which can lead to deformation of the inclined base and to stop dumping of spoil, i.e. to underutilization of the capacity of the blade.

Closest to the proposed invention the technical essence is a way of dumping on an inclined base, which includes the division of a slope inclined bottom on the lens all the way and the prism of active pressure, where the dumping tiers of the blade is carried out in two stages: first on the prism lock to horizon, which is defined by the boundary between the prism lock and prism active pressure, then filling tiers of the blade of the second stage above the horizon. In dumping tiers of the blade of the second phase line f the Ontario dumping tiers of the blade have to line the stretch of a slope inclined to the base at an angle. And the movement of the front dumping blade carried out parallel to the strike of the slope of an inclined Foundation (RF Patent 2211333, a Way of dumping on an inclined base, IPC IS 41/26, publ. 27.08.2003). The prototype.

The disadvantage of the prototype is difficult to fill the tiers of the blade.

The invention allows to achieve a technical result, expressed in dumping tiers of the blade in one turn and storage possibilities paste tailings after processing the ore on sloping ground sustaining dump tier.

This is achieved by the fact that the tier of the blade containing rock overburden and paste-like tails, they are placed separately towards each other, and paste tailings are placed side slope, and a filling layer of overburden and paste tailings to produce the same horizontal level. Stack each subsequent tier of the blade so that the lower edge of Vernisage layer of overburden from the slope coincides with the intersection point of the underlying layer paste-like tails with a sloped base.

Separate styling towards each other overburden and paste tailings after processing the ore dumping tiers to one elevation will enable the storage of paste tailings at the Le processing the ore on sloping ground sustaining dump tier.

The filling layers of overburden and paste tailings to one horizontal level will provide the next overlying layer of the blade.

During the formation of each successive layer of the blade lower edge Vernisage layer of overburden from the slope must be the same at the point of intersection of the lines of the underlying layer paste-like tails with a sloped base, this will increase the stability of the dump tier, consolidated the paste-like tails of the overburden.

The proposed method of dumping on the inclined base is illustrated graphically in figure 1, where 1 is inclined base; 2 - rock overburden; 3 - paste tailings after processing the ore; 4 - horizontal layers of the layer of overburden and paste tailings after processing the ore; 5 - point intersection of the lower edge Vernisage layer of overburden and lines of the underlying layer paste tailings after processing the ores with a sloped base.

The method is as follows.

On the inclined base 1 produce the dumping of rocks tiers of the blade containing the rock overburden 2 and paste tailings after processing the ores 3, stack them separately towards each other, and paste tailings stack from the side of the slope, the filling layer of overburden and paste tailings to produce a single horizontal level 4. Stack each subsequent tier of the blade so that the lower edge of Vernisage layer of overburden from the slope coincides with the intersection point of the underlying layer paste-like tails with a sloped base 5.

The technical result of the claimed invention would eliminate the construction of tailings in mining and processing plant, thereby reducing the area of alienated land.

The method of dumping on an inclined base, including the dumping of rocks tiers of the blade, characterized in that the layer of the blade containing rock overburden and paste-like tails, they are placed separately towards each other, and paste tailings are placed side slope, and a filling layer of overburden and paste tailings to produce the same horizontal level.

SUBSTANCE: proposed method comprises drilling of parallel rows of wells, charging them with explosives and their short-delay blasting. This short-delay blasting of radially arranged charges in membrane layers is performed as follows. First row of wells is blasted, the third one from the bench edge. Then, 1 row of wells is blasted with 25 ms delay while 2 rows of wells are last blasted with 50 ms delay. To locate the membrane layers, rock mass is photographed to define the radius of curvature of bench mining block slope by relationship with due allowance for acoustic stiffness of rocks. Weighted average layer-by-layer quantity of systematic fractures per the width of mining block coverage Wc is defined. Weighted average spacing between two adjacent systematic fractures is defined. Degree of crushing and line of resistance at bench bottom are defined. Sums of rock bed depths and strength factor (by Protodyakonov scale) are calculated. Rock strain rate, clamp factor, explosive potential energy and blast efficiency are defined.

EFFECT: maximum development of rock mass, decreased consumption of explosives, higher yield.
