Yet many of them specialise in oil and mining technology, and Usic is already building infrastructure to support a larger population.
In his state of the nation speech, Mr. Mbeki said the government would shift its focus from its fiscal policy, which is widely praised, to increasing exports of cars, textiles and mining technology and to liberalizing the energy, transportation and telecommunications sectors.
These achievements mainly benefit from China's development and progress in longwall mining technology and equipment.
Each seam adopts protective seam mining technology and eliminates the risk of outbursts.
Many minor coal mines still employ outdated mining technology and equipment, resulting in low efficiency, high safety risk, and low resource recovery rate.
The first set of longwall mining technology and equipment for 7.2 m cutting height were successfully launched and were used at Hongliulin mines in 2011.
The method is based on a computer program LogTrans developed by Centre for mining technology and equipment (CSIRO/CMTE) for geological interpretation.
To solve the safety, efficiency and high-recovery-rate mining problem, we develop the fully mechanized caving mining technology and equipment with large mining height for super thick coal seam.
At present, the key technical problems to achieve coal mining safety, efficiency, and high recovery ratio are the surrounding rock control in strong strata behaviors working face and the safety, efficiency mining technology, and equipment development in complicated mining seam.
The whole set of technology and equipment that we develop could exploit coal 6 million tons per year, which is the first time that imported products are completely replaced with the domestic high-end longwall mining technology and equipment.
