description
BO-400B series multifunctional roadheader is a special equipment used for non-explosive tunnel excavation. It is suitable for 5.5~8m tunnel excavation. It integrates high-frequency rock breaking, soft soil fast excavation, contour finishing, spray dust removal and other functions. When working, it uses high-frequency hammer or breaker to impact and break rock, bucket teeth or drill rods are wedged into the surrounding rock to pry and break rock, and the gravity of the free surface under the surrounding rock is used to automatically break rock. It effectively controls over-excavation and under-excavation and reduces landslides.

Application industries & materials
The Rock-breaking Roadheader, with its powerful breaking ability and high – efficiency operation performance, is widely used in multiple fields and can handle a variety of complex materials.
I. Application Fields
(I) Mine Mining
In the mining of metal and non – metal mines, the Rock-breaking Roadheader plays a crucial role. For underground mines, it can be used for the excavation of development roadways, preparatory roadways, and stoping roadways. By breaking hard rocks, it creates conditions for subsequent ore transportation, ventilation, and drainage. In open – pit mines, when deep mining or mining under special terrain conditions is required, the Rock-breaking Roadheader can quickly open up mining channels and improve mining efficiency. For example, in the mining of metal mines such as iron mines and copper mines, the roadheader can operate stably in different ore layers, ensuring the efficient output of ore.
(II) Tunnel Engineering
- Transportation Tunnels
During the construction of railway and highway tunnels, the Rock-breaking Roadheader is an important construction equipment. It can flexibly cope with surrounding rocks under different geological conditions, such as soft surrounding rocks and hard rock formations. When passing through complex terrains such as mountains and rivers, the roadheader can efficiently break rocks, quickly excavate tunnels, shorten the construction period, and ensure the smooth passage of transportation lines. For example, in the construction of some mountain highway tunnels, the roadheader has overcome the construction difficulties brought by complex geology.
- Municipal Tunnels
In the development of urban underground space, the construction of municipal tunnels such as utility tunnels and subway tunnels is inseparable from the Rock-breaking Roadheader. When constructing in urban areas, the equipment can precisely control the excavation direction and breaking range, reducing the impact on surrounding buildings and underground pipelines. At the same time, its efficient breaking and mucking capabilities can meet the construction progress and environmental protection requirements of municipal projects.
(III) Water Conservancy and Hydropower Projects
In the construction of water diversion tunnels and diversion tunnels of hydropower stations, the Rock-breaking Roadheader can adapt to the complex underground geological environment. Whether it is the hard granite formation or the broken shale and sandstone formations, the roadheader can smoothly excavate through its breaking function. In the tunnel construction of water conservancy projects, the roadheader can also cooperate with other construction equipment to improve the overall construction efficiency and quality of the project.
(IV) Underground Cavern Projects
For the excavation of underground caverns such as underground oil storage, gas storage, and military projects, the Rock-breaking Roadheader can complete the excavation and shaping of caverns under different geological conditions according to design requirements. Its flexible operation performance and powerful breaking ability ensure the construction accuracy and stability of underground caverns.
II. Applicable Materials
(I) Rock – based Materials
- Hard Rocks
This includes rocks with high hardness such as granite, quartzite, and basalt. The Rock-breaking Roadheader can effectively break these hard rocks through a high-strength cutting head and optimized breaking processes. For example, in the tunnel excavation of granite formations, the roadheader can continuously and stably break rocks, ensuring the construction progress.
- Medium – soft Rocks
Medium – soft rocks such as limestone, sandstone, and shale. The roadheader can adjust cutting parameters according to the characteristics of the rocks, quickly break the rocks, and improve excavation efficiency. In the excavation of mine roadways in shale formations, the roadheader can easily handle the work and achieve efficient operation.
(II) Ore – based Materials
During the mining of metal ores (such as iron ore, copper ore, lead – zinc ore, etc.) and non – metal ores (such as coal, gypsum, marble, etc.), the Rock-breaking Roadheader can directly break the ores, which is convenient for subsequent ore dressing and processing. Different types of ores have different hardness and structures. The roadheader adapts to the mining requirements of various ores through an intelligent control system and adjustable breaking parameters.
(III) Other Materials
In some special projects, the Rock-breaking Roadheader can also be used to break materials such as concrete and frozen soil. For example, in the renovation of urban underground projects, when it is necessary to demolish old concrete structures, the roadheader can efficiently complete the breaking task; in the construction of tunnels in cold regions, when facing the excavation of frozen soil, the roadheader can also play its breaking function to ensure the smooth progress of the project.
