Technical Field

The invention relates to the technical field of coal mine pit backfilling, in particular to a landfill system and a landfill process for repairing a mining area.

Background

The step of backfilling the coal mine goaf refers to a cavity or cavity left after underground coal or coal gangue is mined in the coal mine operation process. If the coal mine goaf is not reinforced in time and backfilled, the goaf will collapse after a long time, so that the ground subsides, a collapse pit is formed on the ground surface, and the farmland cannot be cultivated. According to survey and statistics, the land area of China sunk by mining reaches ten thousand mu for years, and the land surface faces the sunk area every ten thousand tons of coal mined. Coal gangue backfill is mainly adopted for backfilling the coal mine goaf at the present stage of China. The coal gangue is solid waste discharged in the coal mining process and the coal washing process, and is a black and gray rock which has lower carbon content and is harder than coal and is associated with a coal bed in the coal forming process. The quantity of the accumulated discharged coal gangue is very large in high-intensity mining of China every year, and the large amount of the coal gangue is piled up, so that not only is the land occupied, but also the environmental pollution is caused along with the continuous increase of coal mining of China, the formed goaf area which is very collapsed is continuously enlarged, the coal gangue is backfilled into the goaf area, the cultivated land can be protected, the mining solid waste can be utilized to the limit, the mining area environment is effectively improved, and the win-win situation is realized by killing two birds with one stone. The coal gangue backfilling technology comprises goaf backfilling, low-lying land filling, coal mine subsidence area reclamation and the like.

In the traditional technology, the muck broken stones are generally directly poured into the mine pit by a muck truck in the landfill of the coal mine area, then the muck broken stones for backfilling are slowly pushed to each area to be buried by a bulldozer, a dump truck, an excavator and the like, and then a soil compactor is used for rolling and tamping, so that the muck broken stones with large structures are filled back into the backfill area of the mine pit, which not only can cause unstable and sparse air attack among backfilling materials, but also has very slow backfilling efficiency and needs a lot of time for distributing and refining. Even some pit areas use the crushing station to carry out the breakage to the dregs rubble of usefulness of will backfilling, transport the scene again and empty after the breakage finishes, increased the harm of raise dust like this in the transportation, very not environmental protection, and greatly reduced work efficiency, and some pit areas are limited, be not suitable for multiple large-scale machine concurrent operation, very inconvenient, so we will design one kind and operate the flexibility, application scope is wide, landfill efficiency is high simultaneously, landfill is effectual, landfill operation cost is low, backfill even compact device and landfill method of dregs rubble distribution.

the first step is as follows: vibrating and feeding: when the pit of the coal mine area needs to be filled, the slag soil and stone blocks for backfilling are pulled to the pit backfilling area through a slag soil vehicle, the slag soil and stone blocks are poured into the upper storage bin (20), the slag soil and stone blocks flow into the vibration hopper (21) through the upper storage bin (20), the vibration motor (22) is started, and the vibration hopper (21) can vibrate and discharge on the two shock absorption pieces (24) and the Y-shaped support frame (23) through the vibration of the vibration motor (22);

the second step is that: crushing and transporting: when the slag and soil stones in the vibration hopper (21) flow into the crushing box (30) from the vibration discharge port (210), the two crushing motors (38) are started to drive the two crushing rollers (37) to rotate, when the stones roll into the crushing rollers (37), the stones are crushed, then the crushed slag and soil stones flow to the belt conveyor (33) along the guide plate (31), and the conveying motors (34) are started to convey the crushed slag and soil stones to be discharged downwards from the outlet leakage-proof plate (32);

the third step: screening and distributing: when the slag and soil crushed stones of the belt conveyor (33) flow into the screen (41) in the screening box (40), the screening motor (46) is started to drive the screen shaft (43) to rotate, so as to drive the rotary table (45) to rotate, one end of the corresponding transmission rod (47) moves along with the rotary table (45), and the other end of the corresponding transmission rod drives the screening connecting rod (48) to move, the screening connecting rod (48) drives the screen (41) to swing back and forth above the screen seat (42), so as to screen the slag and soil crushed stones, after screening is finished, the slag and soil crushed stones flow downwards into the material distribution bin (410), and the motor cannot be started to drive the material distribution auger (412), so that the slag and soil crushed stones are uniformly scattered on the ground of the pit;

the fourth step: scattering and paving: when the slag and soil gravel is laid on the bottom surface of the pit, a grinding lifting rod (51) is started, a grinding disc (511) extends downwards to the ground, a grinding motor (52) is started, a main gear (58) is driven to rotate through the grinding motor (52), so that a planetary gear (59) is driven to revolve and rotate around the main gear (58), and the corresponding grinding disc (511) rotates and circularly moves on the surface of the slag and soil gravel along with the planetary gear (59) through a grinding rotating rod (510) until the slag and soil gravel pile is scattered and laid flat through the grinding disc (511) and conical spines (512) at the bottom;

the fifth step: impact tamping: when the muck and gravel pile is spread flatly, the telescopic end of the hydraulic rod (61) is contracted to drive the tamping side plate (63) to rotate clockwise along the intersection point of the tamping side plate and the tamping support arm (60) until the tamping side plate (63) is vertical to the ground, then the tamping hydraulic rod (65) is started to vertically push the counterweight block (66) downwards, so that the downward pressure is applied to the downward pressing base plate (67), the downward pressing base plate (67) drives the downward pressing vertical rod (611) to vertically extend downwards, when the downward pressing vertical rod (611) moves downwards, the impact head (612) is driven to be in contact with the ground and impact force and vibration waves are applied to the muck and gravel on the ground, the muck and gravel are tightly buried, the position of the impact head (612) can be properly adjusted back through the return force spring (68) every time of impact, and the next time of impact is convenient;

and a sixth step: advancing operation: when the landfill of one pit is finished, the base motor (10) can be started to adjust the construction angle and direction, the device can be moved to the next landfill point through the crawler belt (13) and the four wheels (14), and the device can be used for linear landfill or circular landfill.
