The Dahuang Mountain mine area in Dinghai district, Zhoushan, East China's Zhejiang province recently received recognition from experts for its smart and eco-friendly operations, local media reported on Dec 21.
More than 20 million yuan ($3.14 million) has been invested into establishing an intelligent control and management platform for the mine which has improved production efficiency by 10 percent and boosted comprehensive utilization ratio to 99.8 percent.
"The intelligent platform is connected to 200 video monitoring points and can identify the workers and vehicles entering and leaving the mine area," said Nan Nan from safety and environmental protection department of CICO Mining Co Ltd, manager of Dahuang Mountain mine area.
Nan added that the platform can also monitor the production, sales, equipment operation, and the status of workers on duty.
In addition, the use of intelligent helmets enable workers to upload real-time conditions of the mine to the online platform.
"The platform also helps us control energy consumption and environmental change in the mine area," said Zuo Baoyi from the production technology department.
The sand aggregate testing and research institution in Dahuang Mountain mine area, the first of its kind in China, has been applying its self-developed intelligent equipment and systems, including digital 3D imaging and big data analyzing, to the quality testing of sand aggregate.
According to Hong Weihua, head of the institution, the quality testing system can help optimize the manufacturing technique and achieve real-time quality testing.
The daily shipping weight of aggregate from the Dahuang Mountain mine area exceeded 100,000 metric tons on Nov 24, and the production of machine-made sand is expected to reach more than 4 million tons, making the area the largest production base for machine-made sand in the province.
