Geological workers in east China's Shandong Province have found four reserves of hot dry rock, which equal about 18.8 billion tonnes of standard coal, local authorities said Wednesday.

A geological team managed to dig into the rock in the cities of Rizhao and Weihai, according to the Shandong Bureau of Coal Geology.

Covering an area of 1,500 square km, the rocks can be used in fields such as power generation, heating and oil exploitation.
