(CCTV Finance "Economic Information Network") In recent years, with the continuous optimization of mine development technology, the degree of informatization and intelligence of underground mine production has been continuously improved. Today's series of programs "Specialized, Specialized, Special and New Manufacturing Power" walked into a specialized and special new enterprise in Xuzhou, Jiangsu Province, that produces mine safety equipment, and looked at their unique skills in building smart mines.
The monorail crane is a transportation equipment for underground operation in mines, the underground space is small, the track is hung over the roadway, and the crane car can transport people and goods. In the past, most of the monorail cranes introduced by mainland China used diesel engine traction, but now, intelligent and new energy technologies are also used in underground monorail cranes, reducing air pollution and improving the safety factor.
Qu Shenyue, vice chairman of Xuzhou Jiangcoal Technology Co., Ltd.: We have made a permanent magnet integrated machine, and also made unmanned driving, or remote control driving, which together represents the most advanced monorail crane technology in China.
The geological structure of the mainland is complex, and more than 20,000 mines are gas mines. Production equipment with superior performance and safety is an urgent problem for equipment enterprises.
CCTV reporter Jin Hemiao: In order to further improve the safety factor of underground work, there are now many new products, such as drop-proof and explosion-proof mobile phones, which can be used for underground communication and inspection, and the data will be uploaded to the cloud in time for analysis. There are also multi-parameter gas detectors, which can simultaneously detect methane, oxygen, carbon monoxide and hydrogen sulfide, and hang it on the body to ensure the safety of the environment.
Liao Zeju, chief engineer of Xuzhou Jiang Coal Technology Co., Ltd.: In the past, it was interval positioning, but now the exact location of people can be known, and the distance of a person walking a step (0.3 meters) can be distinguished. Safety monitoring system, if there is danger, it can control the power failure of a certain area in linkage.
This issue specializes in special new and unique skills: 1 minute on the job, 60 seconds safe. New energy, intelligence, equipment upgrading has a trick. Science and technology services underground operations, mining safety has a long way to go.
