Description

The invention relates to the mining industry and can be used in open pit mining of solid minerals using a mining complex and conveyor mining.

Known mobile crushing plants used in conjunction with excavation units such as single-bucket mining excavators and belt conveyors [1-2].

The disadvantage of these technological schemes is low maneuverability when combining the processes of extraction, processing and unloading of rock mass, leading to increased time and productivity.

The closest in technical essence is a method of developing solid minerals using a mining complex with a separate self-propelled crushing reloading unit and a main conveyor [3]. A method based on a mining complex, including the excavation of the blasted rock mass with a quarry hydraulic excavator having working equipment — a bucket, a cabin, a power plant, a rotary platform and a dump conveyor, unloading the rock mass from the bucket to a constant point, ensuring automation of part of the digging working cycle, process automation through a control system and coordination of the interaction of the mechanisms and equipment for converting the cyclic nature of digging into a continuous stream of immersed th mass.

The disadvantage of this mining complex is its low maneuverability when combining the processes of extraction, processing and unloading of rock mass, leading to increased time and productivity.

The technical result consists in increasing the productivity of the process of extraction, crushing and loading of rock mass by providing increased synchronization, safety, reliability of work and lower capital costs.

The technical result is achieved by the fact that in the method of developing solid mineral deposits, including excavating blasted rock with a hydraulic excavator with working equipment — a bucket, a cab, a power plant, a rotary platform and a dump conveyor, unloading the rock mass from the bucket to a constant point with provision automation of part of the working cycle of digging, automation of processes through a control system and coordination of the interaction of the mechanisms and equipment transform of cyclic nature of digging into a continuous stream of submerged rock mass, the rock mass is unloaded from the bucket into a receiving hopper equipped with a classifier for separating the lumpy rock mass from the small and medium lump rock mass sent through an intermediate hopper to the feeder, while the lump rock mass is fed into crusher, crushed and fed sequentially to the feeder and dump conveyor, while the feeder is installed in conjunction with an intermediate hopper and discharge slot and the receiving hopper with the classifier, the intermediate hopper and the crusher are installed under the rotary platform, are rigidly connected with it and placed in the housing fixed on the basis of the mining complex, while the rotary platform is equipped with rolling bearings, mating with the upper part of the housing, and a rotation drive, and the dump conveyor is located perpendicular to the direction of movement of the mining complex, while management and coordination of the interaction of the mechanisms and equipment is carried out using additional itelnyh elements of control and management.

The possibility of forming the required sequence of actions by the proposed means allows us to solve the problem, determines the novelty, industrial applicability and inventive step of development.

The mining complex for implementing the method of developing solid mineral deposits is shown in the drawings.

In FIG. 1 - a General view of the mining complex in the process of scooping rock mass with a bucket; in FIG. 2 - a general view of the mining complex in the process of unloading the rock mass from the bucket into the receiving hopper; in FIG. 3. - view A in FIG. 2.

The method of developing solid mineral deposits is performed using the mining complex 1. The mining complex 1 includes a quarry hydraulic excavator 2 having working equipment — a bucket 3, a cabin 4, a power plant 5 and a rotary platform 6. The mining complex 1 is equipped with a receiving hopper 7 with classifier 8 for separating lumpy rock mass from small- and medium-lump rock mass, intermediate hopper 9, crusher 10, feeder 11, dump conveyor 12 and control and coordination system I work machinery and equipment 13 to transform the cyclical nature of digging in a continuous stream of submerged rock mass. The feeder 11 is installed in conjunction with the intermediate hopper 9 and the discharge slot 14 of the crusher 10. The receiving hopper 7 with the classifier 8, the intermediate hopper 9 and the crusher 10 are installed under the turntable 6, are rigidly connected to it and placed in the housing 15, mounted on the base 16 of the mining complex 1. The rotary platform 6 is equipped with rolling bearings 17, mating with the upper part 18 of the housing 15, and a rotation drive 19. The dump conveyor 12 is perpendicular to the direction of movement 20 of the mining complex 1. The control system and asovaniya interaction mechanisms and work equipment 13 is equipped with additional control and management elements 21. The receiving device 22 is disposed under the conveyor moldboard 12.

The method of developing solid mineral deposits is implemented as follows.

The exploded rock mass is excavated by a quarry hydraulic excavator 2 having working equipment - a bucket 3, a cabin 4, a power plant 5, a rotary platform 6 and a dump conveyor 12. The rock mass is unloaded from the bucket 3 to a constant point, ensuring automation of part of the digging working cycle. Automation of processes is carried out by means of a control system and coordination of the interaction of mechanisms and equipment 13 to convert the cyclical nature of digging into a continuous stream of immersed rock mass. The unloading of the rock mass from the bucket 3 is carried out in the receiving hopper 7, equipped with a classifier 8 for separating the lumpy rock mass from the small and medium lump rock mass sent through the intermediate hopper 9 to the feeder 11. The lump rock mass is fed to the crusher 10, crushed and fed through the discharge the slot 14 of the crusher 10 sequentially to the feeder 11 and the dump conveyor 12. The rotary platform 6 on the rolling bearings 17, mating with the upper part 18 of the housing 15 mounted on the base 16, rotates rotation ode 19. Additional monitoring and control elements 21 of the control and coordination system for the operation of mechanisms and equipment 13 control the passage of the rock mass through the classifier 8 and the crusher 10. The dump conveyor 12 is located perpendicular to the direction of movement 20 of the mining complex 1 and feeds the rock mass to the receiving device 22.

The method improves the productivity of developing solid mineral deposits by reducing the time of the excavation cycle and automating the management of mechanisms and equipment for converting the cyclic nature of digging into a continuous stream of immersed rock mass, and also increases the safety of work, reduces capital costs and increases reliability.
