en.Wedoany.com Reported - Recently, the project "Basic Theory and Comprehensive Control Technology of Gas in Steeply Inclined Coal Seams of High-Altitude Mines," undertaken by Qinghai Energy Development (Group) Co., Ltd., successfully passed its mid-term acceptance in Xining City, Qinghai Province, China. The expert panel determined that the project has achieved all phased objectives, filling a technical gap in the field of gas control in steeply inclined coal seams in high-altitude regions.
Established in 2011 and headquartered in Xining City, Qinghai Province, Qinghai Energy Group is a large state-owned coal enterprise under the provincial government, primarily responsible for the development and operation of plateau coal mines such as the Yuka Mining Area. Located in the Haixi Mongolian and Tibetan Autonomous Prefecture of Qinghai Province, the Yuka Mining Area has an altitude exceeding 3,000 meters, making it a typical high-altitude, low-pressure mining area in China. Targeting the complex working conditions of high altitude and steeply inclined coal seams in the Yuka Mining Area, this project systematically studied the distribution and migration patterns of gas in the special plateau environment, established exclusive standards for gas hazard identification and classification, and developed a complete technical system for gas prevention and control.
To date, this scientific research project has filed two invention patents, which are currently under substantive examination. Additionally, it has published five research papers in high-level international and domestic academic journals and trained three professional graduate students for the industry. During the acceptance process, the expert panel considered the project documentation to be complete and compliant, with scientific research progress meeting planned requirements. They recommended that the project team integrate preliminary laboratory research results to further refine the phased conclusions, providing theoretical support for subsequent on-site engineering validation.
This research aligns with Qinghai Energy Group's strategic direction in recent years to vigorously promote safety through technology. Previously, the group had invested a total of 220 million yuan in digitalization and intelligent construction, aiming to enhance the safety assurance capabilities of plateau mines through technological means. The mid-term results of this gas control project will lay a solid theoretical foundation for comprehensively improving the safe production capacity of high-altitude coal mines in the Yuka Mining Area and the entire Qinghai region. In the future, the project outcomes will directly guide on-site gas extraction and ventilation system optimization, significantly reducing mine safety risks.
