Beijing: China has developed its first coal mine early-warning system that will enable getting advance warning about potential dangers in coal mines.

According to the National Science and Technology Department, China has developed its first system designed to provide early warning of dangers in coal mines.

After passing expert review, it has been now put into operation in three mines in the Shanxi province, the country`s second-largest coal producer.

The system provides all-day data and gives four levels of warning, Xinhua quoted Song Jiancheng, head of the research team as saying Thursday.

Scores of sensors, deployed underground, collect data on factors including temperature and gas density which can be used to predict the likelihood of floods, explosions and other dangers.

The information is transmitted to a control centre above ground for processing and production of reports.

China is the biggest coal producer but frequent accidents have given rise to safety concerns both at home and abroad.

As a result, China has issued a national outline to enlist the help of pre-warning technology in ensuring public safety before 2020. The system will dramatically cut the risk of accidents for coal miners, according to Song.
