Abstract

The invention relates to mining and m. used to transfer and load the rock mass of the underground bunker complex (PBC). The goal is to increase the efficiency of the method by reducing the time for individual operations. The rock mass to the PBC is delivered over the haul horizon by means of mine wagons. They are unloaded into the receiving and unloading production 1. After unloading, the mountain mass enters the crushing chamber 3, where the off-specular pieces are separated in the horizontal plane by the device 4. The latter enter the crusher 5 and, together with the conditioned fraction, are fed by the feeder 6 to the transfer belt conveyor (K) 8 installed in an inclined gallery adjoining the distribution chamber K 10. With the help of a mobile K 11, the mountain mass is distributed along the length of the PBC 12 and from it enters skips 13. Before loading skips g The orienting mass is accumulated and weighed at the loading K 15, which has a weighing device. The accumulation of rock mass is produced when the boot K 15 moves at a slower speed than its movement when loading skips 13. The horn mass spilling from the 13 horn when loading skips enters the mine catcher and then it is poured onto the haul horizon. 3 il.

The invention relates to mining, in particular, to methods of transferring and loading the rock mass of bunker complexes, preferably, when mining end horizons or when deepening (penetrating) the trunk from the underlying horizon to the haul, opened by an auxiliary shaft,

The aim of the invention is to increase the efficiency of the method by reducing the time for individual operations,

FIG. 1 shows a bunker complex, a longitudinal section; figure 2 - section aa in figure 1; on fig.Z - section bb in fig 2.

The scheme for moving and loading the rock mass of the underground bunker complex contains a receiving and unloading excavation 1, in which tilting 2 is installed, a crushing chamber 3 equipped with a device for separating substandard rock mass in the horizontal plane 4 and a crusher 5, vibrating feeder b, an inclined gallery 7, passed at an angle of 16-17 °, with a transfer belt conveyor 8 installed in it, running compartment9, a distribution conveyor chamber 10 with a movable conveyor 11, a storage bin of the horizontal orientation 12, a skip loading chamber 13, in which vibrating feeders 14 and loading conveyors 15 are mounted, equipped with a weighing device 16 and a two-speed drive, the mine divider 17 located above the main haulage level 18.

The method of moving and loading the rock mass is carried out as follows.

From loading points, loaded trucks are delivered by electric locomotives along the main haulage horizon 18 to receiving and unloading production 1 and unloaded with the help of tipper 2. After unloading, the mountain mass enters the crushing chamber 3, where horizontal equipment is separated from substandard pieces by device 4, which enters the crusher 5, and after crushing together with the conditioned fraction, the feeder 6 is fed to the transfer belt conveyor 8, installed in the inclined gallery 7, conjugated with a measure of the distribution conveyors 10, wherein using mobile (katuchego) conveyor 11 is distributed along the length of the storage hopper 12. From hopper 12 accumulating mass of the hearth

one of the feeders 14 installed in the loading chamber skips 13, is uniformly fed to the corresponding loading conveyor 15, equipped with a two-speed

a drive and weighing device 16, which serves to determine the mass of the load on the conveyor belt. When the conveyor 15 is loaded, the belt moves with minimum speed and when reaching

0 with a weight of capacity (capacity) of skip 20, a conveyor of 15 m, the operating vibratory feeder 14 is turned off. When skip 20 stops at its loading level, the conveyor 15 is turned on for the maximum

5 speed and weighted hearth mass is discharged into skip 20 After skip 20 is loaded, conveyor 15 is turned off, skip 20 reaches the surface, and loading cycle of conveyor 15 and weighing the load mass

0 is repeated. Waking up with the skies of the forge horn, the mass enters the mine distributor 17, from where it is loaded into the trolley 19, which is in the free-running excavation 21 of the main haulage horizon 18. The wagon5 is transported to

receiving and unloading production 1 and unloading tipper 2
