The development history of scraper conveyor technology(Part one):foreign technology
Scraper conveyor is the"backbone"equipment of underground coal mining working face,which has experienced 6 technological changes,and promoted the upgradation of coal mining technology and greatly improved production efficiency.The first technological upgradation occurred from 1900 to 1940,the birth of the removable scraper conveyor drove coal mines to enter the era of semi-mechanized mining;the second technological upgradation came from 1940 to 1950,when the flexible scraper conveyor was created and the coal mine entered the era of mechanized mining;the third technological upgradation was formed from 1950 to 1985,the creation of self-moving scraper conveyor put coal mines into the era of fully mechanized mining;the fourth technological upgradation appeared in 1985 to 2000,the development of heavy scraper conveyor forwarded the era of high-yield and high-efficiency fully mechanized mining;the fifth technological upgradation was formed from 2000 to 2010,the development of automated scraper conveyor made the coal mines towards the era of digital fully mechanized mining;the sixth technological upgradation began in 2010,innovative intelligent scraper conveyor opened the era of intelligent mining with few people.The United Kingdom and Germany had made great contributions to the start-up of the scraper conveyor,and developed a variety of early scraper conveyors.The Soviet Union played an important innovative role in the serialization of scraper conveyors and their matching with mechanized shearer.On this basis,the United Kingdom combined Anderton drum shearer with pile-type supports and flexible scraper conveyor into a fully mechanized coal mining unit in 1954,creating the world's first fully mechanized mining face.Since the beginning of 21st century,the center of world's coal mining has gradually shifted to China,and the research and manufacturing influence of foreign scraper conveyor has been declining year by year,and China has gradually become a manufacturing powerhouse for scraper conveyors.
