In underground engineering construction and mineral resource extraction, tunneling machines play a crucial role. They are indispensable in the excavation processes of coal mine roadways, tunnels, and hydraulic culverts, and can operate in both soft and hard rock formations. The cutting pick is a key component installed on the tunneling machine's cutter head, directly contacting and cutting through coal and rock.
Shandong Aide won a bid for a coal mine project in Gansu in early 2025. During roadway excavation, the mine encountered challenges such as continuous geological structures and high roadway pressure. Shandong Aide arranged for engineers to actively participate in the mine's problem-solving discussions and conducted detailed professional technical analyses. They implemented differentiated cutting pick configurations for various working conditions, assisting the mine in safely and efficiently completing the construction plan, earning unanimous recognition from the comprehensive excavation team and mine leadership.
The construction primarily utilized two types of U135 wear-resistant cutting picks: alloy bean and alloy composite coating. In such complex working conditions, these picks fully demonstrated Shandong Aide's exceptional wear resistance and impact toughness for hard rock cutting picks. This not only reduced operational time but also achieved the goal of reducing manpower and improving efficiency, enabling rapid excavation. The single-shift excavation footage increased from 1.7 meters to 3.1 meters, allowing the working face to be delineated 17 days ahead of schedule, laying a solid foundation for the steady continuity of coal mine production.

Shandong Aide's tunneling machine cutting picks exhibit strong geological adaptability, enabling stable construction in coal mine roadways, tunnels, and hydraulic culverts with rock hardness above f15. They offer stable cutting performance, minimal wear, long service life, and low replacement frequency, while also being compatible with renowned domestic and international tunneling machines such as XCMG, Sany Heavy Industry, Jiamusi, and Sandvik.

The U135 wear-resistant cutting picks provide robust support for underground engineering construction and create favorable conditions for the efficient utilization of China's mineral resources. In the future, with continuous technological advancements, it is believed that Shandong Aide will produce more "hardware" to further enhance the efficiency of mineral resource extraction in China.
