XCMG's new breakthrough! Successfully achieved large-angle anchoring!
May 30,2024
Recently, good news came from a coal mine in Shanxi Province, which is 100 meters underground. XCMG anchor digger has successfully achieved large-angle anchor digging operation. This is a new breakthrough.
Under the mine, the large-angle anchoring operation was successfully realized.
Why is it so popular?
Before answering this question, let us first understand the on-site situation.
The geological conditions of this coal mine are complex, and the average inclination of the coal seam is 36°, which is a large-angle three-soft coal seam mining mine. A large-angle uphill tunnel with a designed length of 800 meters, a height of 4.2 meters, a width of 5.4 meters, and a slope of more than 21° is a major construction problem.
"The climbing ability of the conventional domestically produced tunnel boring machine is 16°, which cannot meet our needs..." Previously, the project used blasting construction technology, and the average monthly footage was only 30 meters. How to improve efficiency better and faster while ensuring safety? XCMG has had in-depth communication with the project party time and time again to increase traction and braking force, strengthen the track grip, increase safety auxiliary traction, improve the performance of the hydraulic system, improve the adaptability of the loading mechanism, and increase the number of airborne anchor drilling rigs... Through customized professional design, this "bottleneck" problem has been broken through. Customized XCMG anchor boring machine, intelligent EBZ260M-4H with large slope hard rock, integrates excavation, support, dust removal and other functions, greatly improves production efficiency, and successfully breaks through the difficulty of large-angle anchor boring. Now, it can steadily advance 50m per month, which is more than 60% higher than the original efficiency.
Compared with blasting construction, the intelligent EBZ260M-4H anchor boring machine for large-slope hard rock is safe and efficient, and can form a tunnel in one go; compared with ordinary tunnel boring machines, the use of airborne anchor drilling rigs replaces manual anchoring operations and reduces labor intensity.
At the same time, the anchor drilling rig can also achieve advanced zero-empty top operations and all-round anchoring, making construction safer and more convenient, with more guaranteed quality, and effectively reducing costs such as manpower and financial resources.
Research and develop intelligent underground mines
New equipment and new technologies
XCMG's pace has never stopped
In the future
XCMG will take advantage of the momentum and reach new heights
