Application Industries

1. Mine Roadway Engineering：During the excavation of roadways in metal and non – metal mines, the BOG413A Intelligent Integrated Drilling and Arch – frame Installation Trolley can quickly complete double rock – drilling operations, providing precise blast holes for blasting and mining, thus accelerating the ore extraction process. Meanwhile, it can efficiently carry out arch – erecting operations, installing support arches in a timely manner, effectively ensuring the stability of the roadway during mining and reducing the risk of collapse. It is especially suitable for roadway construction in complex environments such as deep mining.
2. Highway and Railway Tunnel Construction：Whether it is mountain tunnels, urban subway tunnels, or cross – sea and cross – river tunnel projects, this trolley can meet the construction requirements of full – face and bench methods. In the drilling process, it can accurately drill various blast holes for blasting and excavation, controlling the tunnel excavation contour. During arch – erecting operations, it can quickly install steel arches to form the initial support structure, ensuring the safety and quality of tunnel construction, improving construction efficiency, and shortening the construction period.
3. Water Conservancy and Hydropower Projects：In projects such as diversion tunnels and headrace tunnels of hydropower stations, as well as water conveyance tunnels in water conservancy projects, the BOG413A trolley can perform drilling and arch – erecting operations according to geological conditions. In areas with complex geological conditions, strengthening the support through timely arch – erecting can prevent groundwater seepage and surrounding rock deformation, ensuring the smooth progress of the project and creating favorable conditions for subsequent lining construction.
4. Pumped – Storage Power Station Projects：During the construction of underground powerhouses and water conveyance system tunnels in pumped – storage power stations, this equipment can efficiently complete drilling and arch – erecting tasks. Its precise drilling operations help optimize the blasting effect and reduce over – excavation and under – excavation. The rapid and stable arch – erecting operations can promptly support the excavated caverns, maintaining the structural stability of the caverns and laying a foundation for the safe operation of the power station.

Application Materials

1. Rock：The equipment mainly acts on various types of rocks, such as granite, basalt, limestone, and sandstone. Different rocks have diverse characteristics in terms of hardness, toughness, and fracture development. For example, granite has high hardness, which places strict requirements on the rock – drilling performance of the equipment. Sandstone is relatively softer but may have a loose structure, and measures need to be taken to prevent hole collapse during drilling. These characteristics influence the selection of the equipment’s operating parameters and construction techniques.
2. Steel Arches：The steel arches used in arch – erecting operations are usually made of high – strength steel, such as Q235 and Q345. These steels have excellent compression and bending resistance. Steel arches come in various structural forms, including I – beam arches and U – shaped steel arches, and can be selected according to the stress conditions and stability requirements of the tunnel surrounding rock, providing reliable support for the tunnel.
3. Drill Rods and Drill Bits：Drill rods are generally made of alloy steel, such as chromium – molybdenum alloy steel, which has high strength and fatigue resistance and can withstand the huge torque and impact force during drilling. Drill bits are classified into various types according to rock characteristics. For example, cemented carbide drill bits are suitable for medium – hard rocks, while diamond drill bits are often used for hard rock drilling. They directly contact the rock, and their quality and performance directly affect the drilling efficiency and quality.
4. Auxiliary Materials：This includes lubricating oil, hydraulic oil, sealant, etc. Lubricating oil is used to lubricate the moving parts of the equipment, reducing friction and wear. Hydraulic oil serves as the working medium of the equipment’s hydraulic system, transmitting power and ensuring the normal operation of components such as rock – drilling arms and arch – erecting mechanisms. Sealant is used to prevent leakage in the hydraulic system, ensuring the reliability and stability of the equipment.
