A roadheader is a type of heavy construction equipment used primarily in underground mining and tunneling projects. It features a rotating, sharp-edged cutter head that can efficiently break through rock and soil. Roadheaders are versatile and can operate in various geological conditions, making them ideal for creating tunnels for transportation, utilities, and other infrastructure. These machines are equipped with a conveyor system that transports the excavated material away from the cutting area. Roadheaders are often preferred over traditional drilling and blasting methods because they reduce vibrations and improve safety in confined spaces. They are commonly used in projects involving coal mining, subway construction, and hydroelectric tunnels.
