en.Wedoany.com Reported - During the 10th China Brand Day, CREG held a "Bauma Show" for mine and tunnel construction machinery, centered on independent innovation, showcasing core equipment for mechanized tunnel construction, intelligent complete sets of mining equipment, and a matrix of new energy zero-carbon equipment.
In the field of intelligent mining equipment, CREG focuses on the complex geological conditions of coal and non-coal mines, launching a series of solutions. The mining hard rock Tunnel Boring Machine "Pioneer" has been put into operation, effectively alleviating the tension in mining and excavation continuity; the integrated shaft mechanized construction solution has broken through the limitations of traditional techniques; the EJM340/4-2 Bolter Miner integrates excavation, bolting, transport, and dust removal, suitable for full coal, semi-coal rock, and other geologies; the CYTJ64 mining hydraulic drilling jumbo adopts a 2.8-meter narrow-body design, adapted to narrow tunnels, and is equipped with a high-power rock drill and wireless remote control function.
Tunnel-specific equipment covers all scenarios from urban subways to plateau railways. The CTR300A boom-type roadheader integrates cutting, walking, loading, and dust removal functions, suitable for Grade IV-V surrounding rock and hard rock below 100MPa, and has been applied in projects such as the Guiyang Metro and phosphate rock mining. The DJ series intelligent drilling jumbos include the DJ3E three-boom and DJ2E two-boom models, the latter featuring a narrow-body lightweight design and equipped with seven intelligent functions. The MT1G plateau-type intelligent bolting and grouting integrated jumbo can adapt to environments above 3,500 meters in altitude, integrating drilling, grouting, and anchor rod installation.
New energy zero-carbon equipment is centered on pure electric drive. The GJ3G-EV arch installation vehicle features low-temperature cold start performance, capable of multi-process operations such as arch installation and mesh laying, while charging during operation. The HP3017-EV wet shotcrete machine supports dual modes of pure electric travel and tethered operation, with a spraying efficiency of 30 cubic meters per hour, and has been used in the Layue Tunnel of the Plateau Railway.
In terms of intelligent construction and core supporting components, the IRC-I remote command vehicle integrates functions such as remote control, construction information collection, and status monitoring, realizing intelligent management of tunnel construction. The shield/TBM cutter series has overcome multiple core technologies such as inserted tooth disc cutters and pressure-adaptive disc cutters, built an intelligent production line, and provided products and maintenance services for over a thousand projects worldwide.
From mines to tunnels, from green and low-carbon to intelligent and efficient, CREG is driving the upgrade from products to solutions. At the new starting point of China Brand Day, CREG will rely on independent innovation to continue deeply cultivating underground space development.
