Application industries & materials
The Mine – used Hydraulic Tunneling Drill Jumbo, with its powerful hydraulic drive system and high – efficiency drilling capabilities, plays a crucial role in multiple industries and can handle a variety of complex materials.
I. Application Fields
(I) Metal Mine Mining
In metal mine mining, the Mine – used Hydraulic Tunneling Drill Jumbo is an indispensable piece of equipment. It can operate efficiently in the excavation of development roadways, preparatory roadways, and stoping roadways in underground metal mines. When it comes to the mining of various metal ores such as copper, iron, lead – zinc, etc., this drill jumbo can provide high – quality blastholes through precise drilling operations, thereby improving the blasting efficiency and crushing quality of the ore and enhancing mining benefits. Meanwhile, in the complex underground mine environment, its flexible drill arms and stable hydraulic system can adapt to different requirements of roadway cross – sectional shapes and sizes, and can complete drilling tasks even in narrow or irregular spaces, ensuring the smooth progress of mine mining.
(II) Non – metal Mine Mining
- Coal Mining
In underground coal mines, the Mine – used Hydraulic Tunneling Drill Jumbo is mainly used for roadway excavation and support drilling operations. During the excavation of coal seam roadways, anchor holes drilled by the drill jumbo are used to install bolts to support the surrounding rock of the roadway, enhancing the stability of the roadway, preventing roof collapse and roadway deformation, and ensuring the safe production of coal mines. In addition, in gas drainage work, the drill jumbo can drill deep and precise gas drainage holes, helping to efficiently drain gas, reducing the risk of coal mine gas explosions, and improving the underground working environment.
- Other Non – metal Mines
For non – metal mines such as limestone, marble, and gypsum mines, the Mine – used Hydraulic Tunneling Drill Jumbo can be used for the excavation of mine roadways and the drilling and blasting work before ore mining. In limestone mines, the blastholes drilled by the drill jumbo are used for blasting and mining, breaking large pieces of limestone into small pieces that are easy to transport and process; in marble mines, the drill jumbo needs to precisely control the drilling position and depth to ensure the complete mining of marble blocks, improving the yield and quality of marble.
(III) Tunnel Engineering
- Railway and Highway Tunnels
In the construction of railway and highway tunnels, the Mine – used Hydraulic Tunneling Drill Jumbo undertakes important drilling tasks. Whether it is the construction of long tunnels through mountains or short tunnels in cities, the drill jumbo can carry out efficient drilling under different geological conditions according to the design requirements of the tunnel. For hard rock formations, its powerful hydraulic rock drills can quickly break the rock and drill high – quality blastholes, providing a basis for tunnel blasting and excavation; in weak surrounding rock sections, the drill jumbo can carry out advanced support drilling operations, installing advanced support structures such as pipe roofs and small 导管 to reinforce the surrounding rock of the tunnel, preventing collapse accidents and ensuring the safety and progress of tunnel construction.
- Water Conservancy and Hydropower Tunnels
In water conservancy and hydropower tunnel projects such as water diversion tunnels and diversion tunnels in hydropower station construction, the Mine – used Hydraulic Tunneling Drill Jumbo also plays a key role. Since water conservancy and hydropower tunnels often need to pass through complex geological areas, such as fault fracture zones and karst formations, the flexibility and adaptability of the drill jumbo are particularly important. It can carry out drilling operations under these complex geological conditions, providing support for tunnel excavation, support, and geological treatment. For example, when passing through a fault fracture zone, the grouting holes drilled by the drill jumbo can be used to inject reinforcing materials such as cement slurry to improve the stability of the surrounding rock.
(IV) Underground Cavern Projects
In the construction of underground caverns such as underground oil storage, gas storage, and military projects, the Mine – used Hydraulic Tunneling Drill Jumbo is used for the excavation and support drilling of caverns. Through precise drilling operations, the drill jumbo can create conditions for blasting excavation according to the design requirements, forming cavern spaces that meet the specifications. At the same time, during the support process of the caverns, the drilled anchor holes, cable – anchor holes, etc. are used to install support components, ensuring the stability and safety of the cavern structure and meeting the construction requirements of different types of underground caverns.
II. Applicable Materials
(I) Various Rocks
- Hard Rocks
This includes rocks with high hardness such as granite, quartzite, and basalt. The Mine – used Hydraulic Tunneling Drill Jumbo is equipped with high – power hydraulic rock drills that can generate strong impact force and torque, effectively breaking these hard rocks. When encountering granite formations during tunnel excavation or mine mining, the drill jumbo can adjust hydraulic parameters to control the working intensity of the rock drill, adapting to different hardness levels of granite and ensuring the drilling speed and quality.
- Medium – soft Rocks
For medium – soft rocks such as sandstone, limestone, and shale, the Mine – used Hydraulic Tunneling Drill Jumbo can carry out drilling operations more efficiently. Its flexible drill arms and precise positioning system can quickly and accurately drill the required blastholes or support holes in medium – soft rocks. For example, in the excavation of roadways in sandstone formations, the drill jumbo can quickly complete the drilling task, saving time for subsequent blasting and support work and improving the construction efficiency.
(II) Ores
Whether it is metal ores or non – metal ores, the Mine – used Hydraulic Tunneling Drill Jumbo can play a role in the mining process. For metal ores, the blastholes drilled by the drill jumbo are used for blasting and mining to separate the ore from the ore body; for non – metal ores, such as coal seams in coal mines and gypsum layers in gypsum mines, the drill jumbo can carry out various operations such as mining drilling, support drilling, and gas drainage drilling. Different types of ores have different hardness and physical properties. The drill jumbo can adjust parameters such as the pressure of the hydraulic system and the rotation speed of the rock drill to meet the drilling requirements of various ores, ensuring the smooth progress of the mining work.
