Recently, good news arrived from the Kunlun Mountains: the SWDE165BF down-the-hole (DTH) drill rig independently developed by Sunward bravely ventured into the "forbidden zone of life" and successfully overcame the challenges posed by the high-altitude, extremely cold environment, "showing its prowess" at the Huoshaoyun lead-zinc mine at an altitude of 5,600 meters and winning customer favor.

The Kunlun Mountains, ancestor of ten thousand mountains, have an average altitude of 5,500-6,000 meters, an average annual temperature of -3.9°C, and a minimum temperature that can reach -30°C, with low oxygen, low temperatures, and water scarcity. The largest lead-zinc mine in all of Asia—the Huoshaoyun lead-zinc mine—is located here. The mine is developed by Xinjiang Baodi Construction Company. Proven lead-zinc metal reserves in the mining area have reached 19.2 million tons, and the ore grade is extremely high, with annual output value reaching 15 billion yuan. However, the high-altitude and extremely cold environment of the mining area has caused difficulties for both equipment and personnel.

Faced with such harsh conditions, the Sunward SWDE165BF DTH drill rig, relying on its excellent performance, demonstrated a powerful and stable working state at the Huoshaoyun lead-zinc mine, winning unanimous praise from mine staff and creating value for the customer.

According to the R&D personnel, the drill rig's air intake system uses a large-capacity, low-resistance air filter, which can provide sufficient intake air for the engine and air compressor. For the high-altitude and extremely cold environment, the post-treatment system has also been reasonably matched to ensure normal operation. To address the issue of engine power loss, the entire machine is equipped with a large-flow air compressor and a large-displacement main pump, and adopts a patented high-torque power head, offering strong rock formation adaptability and high reliability.

"It is precisely thanks to the powerful overall performance of the machine that it efficiently completed various drilling operations in the high-altitude mining area. The fact that the DTH drill rig can operate smoothly at an altitude of 5,600 meters at the Huoshaoyun lead-zinc mine further proves that Sunward's rock drilling equipment has strong high-altitude adaptability," feedback from on-site staff noted.

In addition to the DTH drill rig, "Sunward green" excavators and mining trucks and other equipment are also participating in operations at the mine. With the continuous advancement of technology, Sunward will upgrade and transform the equipment in the later stage to help customers achieve the goals of "smart mine" and "green mine." In addition, Sunward will continue to leverage the advantages of "pilot-style innovation" to provide more efficient, environmentally friendly, and intelligent products and services to the national mining sector.
