Xiwan Open-pit Coal Mine Passed the Acceptance Inspection for China’s First Group of Intelligent Demonstration Coal Mines

Recently, the Xiwan open-pit coal mine of Shaanxi Shenyang Coal Co., Ltd., a subsidiary of CHN Energy, passed the acceptance inspection for China’s first group of intelligent demonstration coal mines, making it the first state-class intelligent demonstration coal mine under CHN Energy. This also marked that CHN Energy has stood out of its peers in the construction of intelligent open-pit coal mines. A national expert team headed by Ge Shirong, an academician of the Chinese Academy of Engineering and president of China University of Mining and Technology (Beijing), conducted the acceptance inspection.

After careful evaluation and assessment, the expert team concluded that the data network platform built by the Xiwan open-pit coal mine combines three networks and achieves integrated, centralized monitoring and control of coal washing and dressing as well as intelligent, integrated mining management and control. In addition, the coal mine has built an intelligent management platform for blast design, drilling and blast, geological surveying, and mining, realizing digital, efficient management and control of open-pit coal mine production ranging from design and operations to management. Besides, it has formed an unmanned vehicle group and an intelligent transportation dispatching system for open-pit coal mines, achieving large-scale operation of open-pit mine unmanned trucks. Moreover, an intelligent operation and maintenance system for auxiliary equipment in the mining area has been built, and centralized monitoring of slopes, power supply, heating, water supply and drainage has been realized. The intelligent inspection operation robots the and intelligent loading and delivery system it developed help achieve real-time, dynamic monitoring and intelligent operation and maintenance of the production process of its coal dressing plant. Members of the expert team unanimously agreed that the intelligent development of the Xiwan open-pit coal mine had reached the standards for an intermediate intelligent demonstration coal mine, and its coal dressing plant had met the requirements for an intermediate intelligent coal dressing plant.
