The country’s first system designed by the National Science and Technology Department has been deployed in three mines in North China’s Shanxi province, China’s second-largest coal producer following successful expert review.

The system offers data for the entire day and delivers four levels of warning, according to Song Jiancheng, head of the research team as reported by Xinhua.

The warning system comprises various underground sensors to collect information on factors including temperature and gas density which can be used to understand the occurrence of floods, explosions and other dangers in mines.

The data is transmitted to a control center above ground which will be further processed for production of reports.

China plans to deploy the system will be deployed in other coal mines nationwide after further improvements to have clearer analysis.
