Background technology
Coal is for modernization industry, either heavy industry or light industry；Either energy industry, metallurgical work
Industry, chemical industry, mechanical industry or light and textile industries, food industry, transportation, all play an important role, various
Industrial department will all consume a certain amount of coal to a certain extent, therefore someone claims coal to be industrial " real grain ".
One of the main energy sources that human world uses since being 18th century.Although the critical positions of present coal are gradually by oil institute
Instead of, but within the quite a long time from now on, increasingly exhausted due to petroleum resources, inevitable trend is decayed, and coal because
Huge for reserves, scientific and technical rapid development in addition, the new technologies such as flo gasifying of coal reach its maturity, and are used widely, coal
It is coke production big country and coke city of the world that charcoal, which will become one of the irreplaceable energy in human being's production life China,
The leading exporter of field.2003, global coke output was 3.9 hundred million tons, and China Coke yield reaches 1.78 hundred million tons, was accounted for about complete
The 46% of ball total output.In terms of outlet, 14,750,000 tons of the coking coal in Kuomintang-Communist outlet in 2003,4,580,000 tons of middle outlet European Union, about
Account for 1/3.2004, middle Kuomintang-Communist exported 14,720,000 tons of coke, is equivalent to the 56% of global coke total trade volume, international Coke Market
Still supply falls short of demand.A total of about 327,000,000 tons of China Coke yield in 2008, in January, 2009 to September coke output 25276.87
Ten thousand tons.
Since some small-sized mining equipments need to move back and forth position, but mining area is with a varied topography, some places are very
Hardly possible vehicles drive can only lean on manpower, and during the installation process, since mining area sundries is more, is mounted directly and holds on the ground
Damage easily is generated to equipment, some existing mounting support structures are complicated, and installation steps are cumbersome, and not convenient for transportation.
