China's coal, metallurgy and mining is developing in the direction toward the large-scale development. The semi-continuous mining which regards the crushing plant as the key equipment is gradually been widely used. The large crushing station host device has been depending on the industrial products of developed countries of Europe and the United States. Therefore, the development of new energy efficient crushing equipment to replace imported products to meet the needs of domestic large-scale mining is imperative. Coal intensive and efficient production is the trend of the development of the coal industry in the world, and it is also the direction of the development of China's coal industry. Phased advancing measures have been taken for the intensive and efficient development of mining technology. First high yield and efficient mine construction is carried out on the basis of mining mechanization. Subsequently, on the basis of the double high mine construction, the efficient development of mining technology is promoted to improve the economic benefits of the high-yield and efficient mine gradually improved. Practice has proved that the intensive and efficient production is the only way for the survival and development of China's coal enterprises. At the same time,the intensive and efficient production is also the necessary means to improve coal mining technology competitiveness in the world coal market.China is the world's most important coal production base, because the coal seam conditions is the best in the world. Since 1990, the mechanized mining caving coal technology has made a major breakthrough, especially in terms of the top coal face caving equipment modification, pressure observation, caving technology test, explore top coal movement law and increase the recovery rate , study of multiple projects, we have made a series of achievements in scientific research. The main technical indicators have reached the international advanced level. At present, accompanied by a sharp increase of coal demand, coal mining mechanization indicators will also increase in the development of coal mining equipment, which provides a broad market prospects. Secure coal supply is one of the key for the country to strengthen macro-control of the coal industry. Mining coal production potential and accelerating the construction of large coal bases is an important measure. For this reason, we should substantially increase the level of mechanization to to complete coal production structure optimization adjustment under the protection of a prerequisite for a stable supply of coal.As a result, we should vigorously develop the new generation of crushers for the development of the national economy. For example, the jaw crusher provider can optimize the structure of the impact crusher. Stone crusher plant : http://www.crusher-export.com/hammer_crusher.htmBall mill : http://www.mine-crusher.com
