Application industries & materials
The Boom – type Roadheader – Anchor Machine, as an advanced device integrating excavation and support functions, plays a crucial role in multiple fields and is suitable for a variety of materials with different characteristics.
I. Application Fields
(I) Coal Mining
In underground coal mining operations, the Boom – type Roadheader – Anchor Machine is one of the main equipment. It can efficiently excavate roadways in coal seams, opening up channels for subsequent coal mining, transportation, ventilation, and other work. Due to the complex working environment in coal mines, the stability of roadways is of vital importance for safe production. While completing the excavation task, the Boom – type Roadheader – Anchor Machine can immediately carry out bolt support for the roadway, timely reinforce the surrounding rock of the roadway, and effectively prevent safety accidents such as roof collapse and roadway deformation. Whether it is the roadway excavation of thin coal seams, medium – thick coal seams, or thick coal seams, the Boom – type Roadheader – Anchor Machine can adjust the cutting parameters according to the thickness and hardness of the coal seam to achieve precise and efficient operation. At the same time, its intelligent control system can monitor the equipment operation status and roadway support situation in real – time, further ensuring the safety and efficiency of coal mining.
(II) Metal Mine Mining
The Boom – type Roadheader – Anchor Machine also performs excellently in the roadway excavation projects of metal mines. The rock properties in metal mines are diverse, and the hardness varies greatly. With its powerful cutting ability, this equipment can adapt to rock conditions of different hardness levels, from softer shale to hard granite, and can successfully complete the roadway excavation work. Moreover, during metal mine mining, high requirements are placed on the support of roadways to ensure the stability of the ore transportation channel and the safety of workers. The bolt support function of the Boom – type Roadheader – Anchor Machine can flexibly adjust the length, angle, and density of bolts according to the degree of rock fragmentation and stability, providing reliable support for the roadway and meeting the complex requirements of metal mine mining.
(III) Tunnel Engineering
- Small – scale Tunnel and Pilot Tunnel Construction
In the construction of some small – scale tunnels or pilot tunnels, especially in areas with complex geological conditions where large – scale excavation equipment is not suitable, the Boom – type Roadheader – Anchor Machine has unique advantages. For example, in the construction of branch tunnels of urban underground utility tunnels, due to the limited construction space and complex surrounding environment, the compact and flexible characteristics of the Boom – type Roadheader – Anchor Machine enable it to carry out excavation and support operations in a narrow space. At the same time, its precise cutting and support capabilities can effectively control the forming quality of the tunnel and reduce the impact on the surrounding soil and buildings.
- Construction of Auxiliary Tunnels in Mines
In mine mining, in addition to the main mining roadways, some auxiliary tunnels such as ventilation roadways and drainage roadways also need to be constructed. The Boom – type Roadheader – Anchor Machine can quickly and efficiently complete the excavation and support of these auxiliary tunnels, providing guarantee for the normal production of the mine. By cooperating with other mining equipment, it can further improve the overall construction efficiency and safety of the mine.
II. Applicable Materials
(I) Coal
The Boom – type Roadheader – Anchor Machine is especially suitable for various types of coal. From lignite with low hardness and soft texture, to bituminous coal with moderate hardness, and anthracite with high hardness, it can achieve efficient crushing and loading by adjusting parameters such as the rotation speed of the cutting head, the advancing speed, and the arrangement of cutting teeth. During coal mining, whether it requires fine operation when mining thin coal seams or fast excavation in medium – thick and thick coal seams, the Boom – type Roadheader – Anchor Machine can well adapt to meet the excavation requirements of different coal conditions in coal mining.
(II) Rocks
- Soft Rocks
This includes soft rocks such as shale, mudstone, and gypsum rock. The hardness of these rocks is relatively low, and the Boom – type Roadheader – Anchor Machine can easily cut and break them. When encountering soft rock strata during roadway excavation, the equipment can quickly excavate and simultaneously carry out bolt support in a timely manner to prevent the rock from collapsing due to stress release after excavation, ensuring construction safety and progress.
- Medium – hard Rocks
Medium – hard rocks such as sandstone and limestone are also suitable materials for the Boom – type Roadheader – Anchor Machine. Although the hardness of medium – hard rocks is increased, with the powerful cutting power of the equipment and the optimized cutting structure, effective crushing can still be achieved. When encountering medium – hard rocks, the equipment will automatically adjust the cutting parameters according to the characteristics of the rocks to ensure the excavation efficiency and the normal operation of the equipment, and at the same time, it will timely stabilize the surrounding rock of the roadway through bolt support.
- Some Hard Rocks
For some hard rocks with relatively low hardness, such as granite and quartzite with lower hardness, after technical optimization and parameter adjustment, the Boom – type Roadheader – Anchor Machine can also carry out a certain degree of excavation work. However, when dealing with hard rocks, more attention needs to be paid to the maintenance and upkeep of the equipment to ensure its continuous and stable operation.
