At present, Huangling Mining Company took the lead in applying intelligent unmanned mining technology in the 1001 fully mechanized mining face of No. 1 Coal Mine. This technical achievement comes from the “Research and Application of Unmanned Technology for Domestically Produced Fully Mechanized Mining Equipment in 1.4m～2.2m Coal Seamâ€, which was completed by Huangling Mining Company.
The length of the 1001 fully mechanized mining face of No. 1 Coal Mine is 235 meters, the mining height is 1.1 meters to 2.3 meters, and the recoverable reserves are 1.07 million tons. The geological conditions of the mine are complex, and the thickness of the coal seam on the side of the inlet is extremely uneven. The thickness of the coal seam within the range of about 500 meters is between 1.1 and 1.6 meters.
It is reported that during the installation and commissioning of the 1001 fully mechanized mining face, many difficulties were encountered. For example, in the process of automatic memory cutting, the cable of the shearer cable frequently turns off in the non-stop folding, which affects the automatic coal mining operation.
In order to make the intelligent working face put into use smoothly, Fan Jingdao, secretary of the party committee and chairman of Huangling Mining Company, asked the company to focus on the wisdom of the group, and jointly develop equipment manufacturers to carry out scientific and technological research, strengthen equipment installation and commissioning, and maximize the effectiveness of comprehensive mining equipment. We will strive to build the 1001 fully mechanized mining face into a leading international intelligent unmanned mining face in a short period of time. According to the requirements, the No. 1 coal mine organized technical personnel to improve the intelligent working face, and achieved 12 innovations and solved 66 problems.
Since the 1001 fully mechanized mining face was officially put into use in March this year, remote control of the ground dispatching room has been realized. Through the ground dispatching room and the underground monitoring center, it is possible to remotely control, monitor, data upload, and fault diagnosis of the coal mining machine, hydraulic support, pump station and other equipment in the working face, and realize the work of the ground dispatching room and the tracking monitoring center. Fully automated control and “one button†start and stop. As a result, the No. 1 coal mine realized the linkage control of the self-moving of the transfer machine and the hydraulic support, intelligent height adjustment, chamfering feed, continuous advancement and so on.
Mei Fangyi said that the current 1001 fully mechanized mining face has been established with “mechanized coal cutting machine for coal mining, supplemented by manual remote intervention; hydraulic support and machine action are mainly used, supplemented by manual remote intervention; The automatic production mode, which is mainly based on automatic control and supplemented by manual remote control, truly achieves the goal of “unmanned and unmanned machine operation, and some people are safely on dutyâ€, achieving the goal of reducing people and improving efficiency.
It is reported that the 1001 fully mechanized mining face was jointly operated by the original 11 people (3 coal machine drivers, 5 bracket workers, 1 transport driver, 1 electrician, 1 pumping station driver), reduced to the current 3 (patrol) 1 person for work, 2 operators for monitoring center), random monitoring.
"Since the operation of the 1001 fully mechanized mining face in No. 1 Coal Mine, it has been reported that the working time of the coal miners does not go down. We don't think this is a bad thing. The coal miners can extract the coal in the uphole dispatching room. This is ten years ago. It is unimaginable," said Mei Fangyi.
Mei Fangyi said that the complete production system of the 1001 fully mechanized mining face has achieved normal unmanned, changing the working mode of workers, improving the working environment of workers, improving production efficiency, reducing labor intensity and reducing occupational hazards. Strengthening on-site safety management is of great significance.
At present, the 1001 fully mechanized mining face has created a record of nine-and-a-half-day continuous advancement and has an annual capacity of 2 million tons of coal. Not only that, compared with imported equipment, only the automatic mining equipment automation system can save nearly 30 million yuan, saving labor costs of 5.25 million yuan per year.
It is reported that Huangling Mining Company has begun to study the application of intelligent mining technology in thick coal seams, and further expand the application range of intelligent coal mining technology in the mine.
