The Knowledge of Roadheader

Nov. 11 , 2019

Roadheader is a machine for digging straight underground tunnels.

Roadheader is divided into open type roadheader and shield type roadheader. Prices are generally in the hundreds of millions of yuan. It is mainly composed of walking mechanism, working mechanism, shipping mechanism and transfer mechanism. As the traveling mechanism moves forward, the cutting head in the working mechanism continuously breaks the rock and transports the broken rock away. 

It has the advantages of safety, high efficiency and good roadway quality, but it is expensive, complicated in structure and high in loss. Roadheader is divided into two types: open type roadheader and shield type roadheader, horizontal axis roadheader EBZ and vertical axis roadheader EBH. Prices are generally in the hundreds of millions of yuan, due to the production of domestic roadheader, the price of roadheader is greatly reduced, between one million and 20 million. English: roadheader is a machine for digging straight underground tunnels. It is mainly composed of traveling mechanism, working mechanism, loading mechanism and transfer mechanism. Now the complete set of equipment is changed into a main machine and a second conveyer, and the second conveyer is used to transfer the belt to the transportation well. As the traveling mechanism moves forward, the cutting head in the working mechanism continuously breaks the rock and transports the broken rock away. It has the advantages of safety, high efficiency and good lane quality, but it has the advantages of large cost, complex structure, large loss, high failure rate and high price of accessories.

In recent years, with the rapid development of China's coal industry, the coal mining industry, which is closely linked with it, has also received increasing attention. In the national coal industry science and technology conference and the national development and reform Commission issued the coal industry structure adjustment policy, all involved in the development of large-scale coal underground comprehensive coal mining equipment and other content. Excavation and backstoping are important production links in coal mine production. The national policy is to pay equal attention to excavation and advance excavation. Rapid excavation of coal mine roadways is a key technical measure to ensure high and stable production in coal mines. Mining technology and its equipment level are directly related to the coal mine production capacity and safety. High-efficiency mechanized tunneling and supporting technology is a necessary condition to ensure high yield and high efficiency in mines, and is also the development direction of roadway tunneling technology.  With the development of fully mechanized mining technology, super working faces with an annual output of millions of tons or even tens of millions of tons have emerged in China, which greatly increases the annual consumption of mining roadways, thus making roadway excavation a common and key technology for efficient intensive production in coal mines.
