Abstract

The invention relates to the mining industry and can be used in the formation of dumps in the mode of controlled deformations from rocks (P) with low strength properties. The goal is to increase the productivity of dump works with the use of an excavator-mechlopaty by increasing the capacity of dump dumps with a simultaneous increase in the reliability of control of the process of displacement П in the dumping area while ensuring the safety of work. To the place of unloading transported P with different strength properties. Poured out of the strong p pioneer mound. From it or from the next block, the dump tailings of the lower sub-step 1 are filled with an excavator (E) 2 layer of strong P 3, forming a lateral slope of the lower sub-step from them. Then, weak Ps are unloaded onto them with the formation of a side support ridge 8. Its height is determined by the height of the upper subpath 6. The lower subpath is formed during the direct passage E 2 to the end of the dump deadlock or sections 70–100 m with its shuttle movement. Filling the gap between the support ridge 8 and the slope of the upper sub-accessory 6 is carried out with weak P during the backward passage E 2. After the exit of the weak P on the internal slope of the lateral supporting ridge, the formed space is filled with strong rocks. 2 hp f-ly, 2 ill.

FIG. 2

The invention relates to the mining industry and can be used in the formation of dumps in the mode of controlled deformations from rocks with low strength properties (weak rocks) with the open development of mineral deposits.

The purpose of the invention is to increase the productivity of dump works with the use of an excavator-mechlopaty by increasing the capacity of the dump entry with a simultaneous increase in the reliability of control over the process of displacement of rocks in the dumping zone while ensuring the safety of work.

FIG. 1 shows the plan of the blade; in fig. 2 shows section A-A in FIG. one.

Example. From the stable pioneer embankment or the next block of dumping entry of the lower sub-access 1, an excavator 2 is poured over a layer of strong rock 3, forming a lateral slope of the lower sub-accessory from them. At the same time, strong rocks are poured in front of excavator 2, blocking the pile of weak rocks 4 with them, the height of which is 2-4 m less than the height of the lower sub-accessory. Strong rocks in front of the excavator are poured to the level of the upper platform of the lower access step. A layer of strong rocks 3 is poured into the side slope at the height of the lower sub-step or above the latter by the value of the support ridge 5, the height of which is equal to half the height of the upper sub-step 6.

After dumping a layer of hard rock 3 in the prescribed parameters, weak rocks 7 are laid on them to form a lateral support ridge 8, the height of which is determined by the height of the upper sub-extrude 6. The lower sub-extrude is formed during the forward passage of the excavator to the end of the dump dead end on 60-100 m at its shuttle movement.

The filling of the gap with weak rocks between the support ridge 8 and the slope of the upper sub-step 6 is carried out with the backward passage of the excavator 2 or sections of 60-100 m with its shuttle movement. Weak rocks in the upper

The accessions are poured in the direction from the slope of the upper substation to the internal slope of the support ridge 8 until the lower edge of the next pile of weak rocks reaches the conjugation point with the slope of the reference ridge in the middle of the height of the latter. After that, more durable rocks are laid in the formed gap, forming a route 9 for the new location of the railway track.
