Two coal mines in South China have collapsed, trapping 19 coal miners, according to reports.
Forty-nine out of 71 miners escaped, while three bodies have been recovered.
Rescue efforts to free the trapped miners from the Zhangcun Coal Mine have been held up by high levels of carbon monoxide.
They have halted the operation until they find a safe way to continue, reported China Daily.
The mine caved in on Saturday after it was apparently weakened by heavy rainfall in the Guangxi region.
