Model of Shandong mining machinery Shearer

1. According to the mining height, slope, mineral structure and environment of each coal mine, the type of hydraulic support used in a fully mechanized coal mining face is different

the common hydraulic supports are shield type, support shield type and top coal caving hydraulic support. But to subdivide, there are many other types, such as wire laying, thin coal seam, large dip angle, filling type, end hydraulic support, advanced hydraulic support and so on. However, the main structural forms of the roof of the supporting working face are no more than the three types of shield, support shield and top coal caving hydraulic support

5. Research Report on coal machinery instry (China Coal Machinery Instry Association)

I. Introction to the basic situation
since 2000, the rapid growth of coal demand has driven the unprecedented prosperity of coal mining instry, and the coal equipment instry and service instry, which directly provide services for coal mining, processing and utilization, have also entered the fastest development stage in history, because of the scale of coal proction, coal output, coal consumption, and so on The rapid growth of processing quantity, processing depth and mining difficulty has put forward an urgent demand for coal equipment instry and service instry. The significant improvement of financial indicators such as sales revenue and net profit of coal enterprises has greatly enhanced their ability to purchase new equipment. Therefore, the rising demand fundamentally determines that 2006-2010 is the golden period for the development of coal equipment instry<

origin price equipment capacity (ten thousand tons / year) service life of shearer / scraper (ten thousand tons) service life of hydraulic support (ten thousand tons) automation degree
domestic low 200-500-800 1000-1500 low reliability
manual operation
import is generally more than two times of domestic Relatively weak, 2000-2500-3000 has high reliability
high degree of automation
from the perspective of instrial structure, domestic coal equipment enterprises are generally small in scale and scattered in layout, which means that superior enterprises will have greater comparative advantages in integrating the market, building supporting system, formulating instry standards, etc., and will be easier to stand out, And then grow into a coal equipment giant
from the perspective of equipment level, domestic coal equipment lags behind the international advanced level, and the indicators of equipment reliability, intelligence and informatization are obviously on the low side. However, in the past few years, domestic coal equipment has been continuously improved, and breakthroughs have been made in equipment manufacturing research and development, design and manufacturing
as a big coal country, the gap between domestic high-end coal mining machinery and foreign advanced level is narrowing in recent years, and the market share of domestic procts is also expanding. For example, the domestic hydraulic support market has a total market volume of 2 billion to 3 billion every year, of which the number of imported mechanical equipment is a relatively small part, and the vast majority are domestic equipment
the cost advantage provides domestic coal machinery manufacturers with strong competitiveness in the market. The average price is half cheaper than imported equipment, which is the reason why domestic coal machinery manufacturers can get sufficient orders in China. At the same time, China's coal machinery procts and manufacturers also have certain advantages over similar international companies in providing high-quality and perfect after-sales service, in-depth and detailed understanding of local customers' needs, and in the price and sales of accessories< br />5、 Ranking of domestic roadheader manufacturers
