subject: Major Coal Machine Equipment In The World Advanced Level In Key Technology Was A Breakthrough - Coal [print this page] "China Coal Group subsidiary equipment company has successfully tested a ZY17000/33/75D electric hydraulic controlled high coal Hydraulic Mining, working resistance of 17,000 kN, support strength 1.46 MPa, 7.5 m high support, a world record . "November 5, vice president of China Coal Energy Company Limited, China's coal mining machinery and equipment limited liability company (the" Coal Equipment Company "), Pu-chun, general manager of the" China Energy Report, "told reporters. The stent has successfully developed and fully demonstrated China's major coal machine and equipment R & D capabilities, manufacturing technologies and overall strength has reached world advanced level, the national big thick seam mining pressure to achieve high yield and high mechanized mine exploitation and provided strong support.
10 27, the 13th Coal Mining Technology Conference and Exhibition in Beijing National Agricultural Exhibition Hall. October 26 afternoon, a large truck carrying the hydraulic slowly into open-air exhibition in the Show. Unloading, debugging or frame, frame height reached 7.5 meters. Also with the car arrived in Xi'an Central Coal coal equipment companies produced stand-alone face up to 10 million tons of annual output of large Shearer. "Height" 7.5 meter hydraulic as "Big Mac" as standing in the meeting room, welcoming space, and from other domestic large-scale Coal Products Manufacturing Group, echoed constitute domestic industry in China Coal echelon team.
"All appearance of these large equipment can be said that China's current machines, especially in high-end large-scale coal development in the field machine made of coal increasing the level of a microcosm." Vice president of China Coal Research Shenbao Hong told reporters the total said. He pointed out, there are three figures reflect the present, China Mining Machinery Manufacture high domestic level: Underground support hydraulic height 7.5 m, high-end single-face annual mechanized mining equipment, over 10 million tons, large mechanized coal mining equipment 95% level. These figures are at the advanced level in the world.
"Foreign investors do not believe we
Can build coal machine 'Big Mac' "
Looking up at 7.5 m hydraulic support this monster, the Beijing Coal Mining Machinery Company Equipment Company, deputy chief engineer Li Bingtao lamented: "The previous high-end domestic market coal machine almost monopolized by foreign manufacturers, they think with the level of China's equipment manufacturing , almost impossible Zaochu these 'giant'. "According to him, a few years ago the State Council issued the" speed up the revitalization of the equipment manufacturing industry on a number of opinions ", which states that we should focus on promoting large-scale mining, promoting, and washing equipment at home process. Coal equipment manufacturing industry as a "national team" of equipment in the coal company is duty-bound to take up a number of national key scientific and technological project task, a strong impetus to China's rapid development of coal-machine manufacturing.
