Recently, Shandong Luxi Mining announced that the mining TBM "Kaituo", deployed on the northern rail roadway of Lilou Coal Mine, has successfully completed its entire tunneling mission, marking the successful conclusion of rock roadway construction covering a total bored length of nearly 6.6 kilometers.
Developed by CREG, the "Kaituo" mining TBM features an excavation diameter of 5.83 meters and integrates multiple functions including boring, mucking, support, ventilation and dedusting, and advanced drilling.
The northern rail roadway at Lilou Coal Mine poses major construction challenges, including fault fracture zones, high water inflow, complex geological conditions, and a long drive distance. To address these, CREG's R&D team equipped the TBM with advanced geological prediction and treatment systems, as well as rapid temporary support systems, enabling the machine to quickly pass through fault fracture zones while significantly improving construction efficiency and safety, and effectively improving the working environment for personnel.
