Application Industries

1. Mining Industry：In the mining of metal mines and non – metal mines, rock – drilling jumbos are used for roadway driving and mining operations. They drill blast holes to prepare for subsequent blasting, thus enabling ore extraction and roadway extension. For example, in underground mining, rock – drilling jumbos can efficiently complete deep – hole drilling tasks, improving mining efficiency and safety.
2. Tunnel Engineering Industry：This includes railway tunnels, highway tunnels, urban subway tunnels, and water conservancy and hydropower tunnels. During tunnel excavation, rock – drilling jumbos can drill various types of blast holes, such as cut holes, break – up holes, and perimeter holes, according to different geological conditions and construction requirements. They cooperate with blasting operations to advance the tunnel. Meanwhile, they can also be used for drilling anchor – bolt holes for initial support to ensure tunnel construction safety.
3. Road Construction Industry：In mountainous road construction, when there is a need to excavate tunnels through mountains or carry out slope anchoring projects, rock – drilling jumbos play an important role. For example, in slope protection projects, they drill anchor – bolt holes and install anchor bolts to reinforce the slope and prevent geological disasters such as landslides.
4. Water Conservancy and Hydropower Industry：In projects such as hydropower station construction and water – diversion tunnel construction, rock – drilling jumbos are used for rock foundation drilling operations, such as dam foundation drilling and diversion tunnel drilling. By accurately drilling holes, they provide conditions for subsequent grouting, anchoring, and other processes to ensure the stability of the project structure.
5. Quarry Industry：In quarries, rock – drilling jumbos are used to drill rocks for subsequent blasting and stone extraction. They can quickly and efficiently drill a large number of regular blast holes, improving the efficiency and quality of stone extraction.

Application Materials

1. Rock：The main target materials of rock – drilling jumbos are various rocks, including granite, limestone, sandstone, shale, etc. Different rocks have different properties such as hardness and brittleness, which affect the performance of rock – drilling jumbos and the wear of cutting tools. For example, granite has high hardness, requiring rock – drilling jumbos to have stronger impact and rotation capabilities, and the cutting tools need to have better wear resistance.
2. Drill Rods：They are usually made of high – quality alloy materials, such as steel containing alloying elements like manganese, molybdenum, and chromium. These drill rods have high strength, wear resistance, and good fatigue resistance to withstand the impact and torsional forces during drilling, ensuring smooth drilling and their own service life.
3. Drill Bits：Common materials include cemented carbide and polycrystalline diamond compacts (PDC). Cemented carbide drill bits have high hardness and wear resistance and are suitable for drilling in medium – and low – hardness rocks. PDC drill bits perform well in hard rock drilling, as their diamond layers can effectively cut rocks and improve drilling efficiency.
4. Other Auxiliary Materials：This includes lubricating oil, hydraulic oil, etc. Lubricating oil is used to reduce friction between components such as drill tools and reduce wear. Hydraulic oil is the working medium of the hydraulic system of rock – drilling jumbos, transmitting power and ensuring the normal operation of various hydraulic components.
