Shuangli Mine is located southeast of Longtou Village, Qiezihe District, Qiezihe City, just 3 kilometres from the S308 provincial highway. The mine employs a sloped shaft development system with a central parallel exhaust ventilation system, enabling an expected production capacity of 40,000 tons per year.
The mine primarily extracts coal from Seams 109, 113, 114, and 119, with lean coal as the dominant type. The coal seams have an inclination of 30–40 degrees and an average thickness of approximately 0.7 meters, offering an annual output of 300,000 tons. The mining area spans 5.16 square kilometres, with coal reserves of 9.8 million tons, including coking coal, 1/3 coking coal, lean coal, and meagre coal.
The aggregate investment adds to approximately $50 million, supporting the employment of around 490 local workers, promoting regional economic development and social stability.
