China is the world's producer of coal mining by mining, and mining accounts for more than 97% of China's coal production.
Coal machine equipment in a broad sense includes open-pit mining equipment, safety equipment, exploration equipment, comprehensive mining equipment, comprehensive mining equipment, washing equipment, etc., while narrowly defined coal machinery usually refers to comprehensive coal mining equipment, the core of which is "three machines and one machine" ——Roadheader, shearer, scraper conveyor and hydraulic support.
Three machines and one
The roadheader is used to excavate straight roadways in underground coal mines. The rapid excavation of coal mine roadways is the key technical measure to ensure the high and stable production of the mine.
A shearer is a mechanical device that breaks coal by a rotating working mechanism and loads coal into a conveyor or other transportation equipment. The mining technology and equipment level are directly related to the production capacity and safety of coal mines.
The scraper conveyor is a conveyor device that uses a scraper chain to draw and transport bulk materials in the tank. In the current coal mining face, the scraper conveyor not only transports coal and materials, but also the running track of the coal mining machine. The continuous operation of the scraper conveyor is a necessary condition for the normal production of coal.
The hydraulic support is a structure used to support the roof and control the pressure in the coal mining face. It is an important part of comprehensive coal mining equipment and is used in conjunction with coal shearers to achieve comprehensive coal mining mechanization.
GDP pulling
China's GDP growth is based on industries such as electricity, steel, construction materials, chemical fertilizers, etc., which all require coal as a raw material for power.
This will naturally promote the growth of coal demand, and the source of coal is the integration of existing coal mines, newly mined coal mines and small coal mines in China. The mining of these coal mines is inseparable from the demand for coal mining equipment, and the demand for coal equipment The corresponding production equipment and after-sales service companies are indispensable. This has formed a huge driving force for coal machine equipment from top to bottom.
Pyramid structure
The market pattern of the coal machine industry is roughly as follows: the
coal machine sales revenue of 5 billion to 10 billion companies resides in the group, including China Coal Energy (revenue of coal mine equipment in 2011 was 8.788 billion yuan), Tiandi Technology (2011 coal machine sales of 6.665 billion yuan), Zheng Coal Machinery (product revenue in 2011 was 6.159 billion yuan), etc., the Group's revenue growth rate has always been higher than the growth rate of the coal machine industry's output value, and the ratio of revenue to the industry's output value has gradually increased;
The sales revenue of the second group is between 1 billion and 5 billion yuan. Previously, Sany International (Sales revenue in 2011 was 3.78 billion yuan, an increase of 40.9% year-on-year), and International Coal Machinery (Sales revenue in 2011 was 2.098 billion yuan, an increase of 8% year-on-year ), Pingdingshan Coal Mining Machinery and Shandong Mining Machinery (Sales revenue of 1.637 billion yuan in 2011, a year-on-year increase of 27.6%), etc .; the
third group is the remaining more than 2,000 coal mining machinery companies, this group is no lack of old enterprises and local state-owned enterprises, many 'S income is hovering around 100 million yuan, and more is fierce fighting on the order of tens of millions.
