The 2025 China (Cangnan) Mining Machinery and Equipment Exhibition was grandly held at the Cangnan County Sports Center in Zhejiang Province from April 6th to 8th. The exhibition was hosted by the Cangnan County People's Government and undertaken by the Cangnan County Mining Well and Shaft Industry Association. Mining equipment companies from all over the country gathered together for this grand event. Yier Technology, as an industry innovator, made a stunning appearance with its independently developed KQG-150 Down-The-Hole Drilling Machine and the "small Raise borer Machine" AT-2000 Raise borer Machine.

These two products embody years of R&D efforts by Yier Technology. Their designs fully consider the complex environment and practical needs of mining operations, possessing numerous performance advantages such as being compact and flexible, highly efficient, and safe and reliable. KQG-150 Down-The-Hole Drilling Machine

①Small size: Flexible and convenient, highly adaptable. The entire machine adopts a modular design, with a compact structure: 3.6m long, 1.2m wide, and 1.8m high. It can be transported directly to the designated middle section via a cage without disassembly.

②High efficiency and stability, adaptable to various rock strata. The pusher can pitch within the vertical plane from -5° to +90° and can rotate 360°. The drilling diameter is φ76～φ203mm, making it particularly suitable for drilling annular holes in underground mines.

AT-2000T Raise borer Machine: ① Small size, convenient transportation. The entire machine is 4.05m long, 1.43m wide, and 2.25m high. It also features convenient positioning and quick disassembly functions, better adapting to the needs of mine development. ②Two transportation methods: self-propelled tires and rail towing. This model can achieve convenient transportation in both rail and non-rail mines through the switching of rail wheels and tires.

During the exhibition, Yier Technology's booth became a popular attraction, with numerous industry experts, mining clients, and partners stopping by to exchange ideas. They gave high praise and widespread acclaim to these two drilling rigs. Through in-depth technical exchanges and business negotiations, many companies further strengthened their confidence in deepening cooperation with Yier Technology, jointly opening a new chapter in the construction of intelligent mines.

Currently, the mining machinery industry is at a critical juncture of transformation and upgrading, with intelligence, green technology, and high efficiency becoming the inevitable trend of industry development. Yier Technology understands that innovation is the primary driving force for development. The two small drilling rigs exhibited this time are a precise grasp and practice of industry trends by Yier Technology. Looking to the future, Yier Technology will continue to cultivate the field of mechanical rock breaking, increase R&D investment, and contribute to the development of the mining machinery industry with more advanced technology and higher-quality products.
