Chinese state media are reporting two new mining accidents that killed two miners and trapped 23 underground.
In the first incident, a coal mine was flooded early Wednesday in northern China's Shanxi province, killing two miners. Rescuers are trying to reach 15 miners who failed to escape the flood in Dianwan town, Zuoyan county.
The second accident occurred Thursday in the eastern province of Shandong. A gold mine was flooded in Penglai city, trapping eight miners who were inside.
Officials say the causes of both flooding incidents are being investigated.
China has suffered a string of deadly mine disasters in recent weeks. A mine explosion in Heilongjiang province killed 171 miners in late November, while another blast in Hebei province killed 91 miners earlier this month.
