Description

Large-dip-angle and steep-dip coal receiving groove for fully-mechanized mining reversed loader

Technical Field

The utility model relates to the technical field of cleaning of reversed loading machines, in particular to a coal receiving groove for a large-inclination-angle and high-inclination fully-mechanized mining reversed loading machine.

Background

At present, the domestic large-dip-angle coal seam accounts for 15-20% of the coal reserves and 5-10% of the yield of China, while the large-dip-angle and steep-dip coal seam has no good exploitation mode in China and abroad, the exploitation technical difficulty is high, the exploitation technical difficulty is listed as a 'coal exploitation forbidden zone' abroad, and the casualties of face exploitation personnel are more than 4%.

When mechanized fully mechanized mining is implemented on a steep coal seam with a large inclination angle, the space of a working face is small, and the mechanized fully mechanized mining is different from that of a gentle coal seam in the aspects of rock formation control, equipment structure and arrangement, production process, safety technology and the like, so that the difficulty in comprehensive mechanized mining of the long-wall working face of the steep coal seam is high, especially when the problems of flying gangue prevention and coal throwing are solved, due to the large inclination angle and the large inclination angle, the produced coal and gangue fall down along a slope under the action of gravity, the fully mechanized mining equipment is damaged, and the casualties are most fatal.

When mechanized fully mechanized mining is implemented on the large-dip-angle and steep-dip long-wall working surface, falling coal and gangue are thrown into the lower crossheading transfer conveyor along the inclined surface and transported to the belt conveyor, and are transported out of the mine by the belt conveyor. In the process, the blocky coal and gangue falling from the fully-mechanized mining face are in slope rolling trend to form higher parabolas, the thrown coal and gangue have stronger impact killing power according to different lengths of the mining face, and cause great threat to electromechanical equipment and personnel safety of the lower outlet of the fully-mechanized mining face.

The conventional transfer machine has the following disadvantages:

1. the coal baffle of the coal receiving groove of the transfer conveyor is arranged lower, and when the fully mechanized mining face is inclined at a large inclination angle and steeply, the thrown coal blocks and gangue can jump over the coal baffle, so that great threat is caused to the electromechanical equipment of the lower crossheading and the safety of personnel;

2. the heightening baffle plates of the coal receiving groove of the transfer conveyor are connected by bolts, so that the heightening baffle plates have better rigidity and insufficient flexibility, and when the heightening baffle plates are used for picking a face with a large inclination angle and a steep inclination, the heightening baffle plates are destroyed and degraded when facing larger falling coal or gangue rolling impact;

3. the installation difficulty of the heightened baffle of the common reversed loader is high, the lower gate way of different height sizes is relatively limited, and maintenance and management are relatively difficult.

Aiming at the defects, the two modes of welding or bolting the coal baffle plate and the welding baffle plate and bolting the coal baffle plate on the chute of the transfer conveyor are generally adopted to basically meet the requirements in horizontal or gently inclined mining surfaces, but the coal baffle effect and the safety protection effect are obviously insufficient when the mining surfaces with large inclination angles and steep inclination are adopted, and the transfer conveyor is not practical.

Therefore, based on the above technical problems, it is necessary for those skilled in the art to develop a coal receiving slot for a large-inclination-angle fully-mechanized mining transfer conveyor.
