Hunan geologists said coal-mining is to blame for the appearance of more than 20 sinkholes in Fukou county, Lianyuan city, Xinhua News Agency reported on Jan 15.

The sinkholes have occurred in Wenquan and Yijia villages since the end of August 2012, with the biggest covering some 200 square meters.

They have caused serious damage to people's livelihoods, affecting the water supply of 4,000 residents and the irrigation of 33.3 hectares of farmland.

More than 20 families' houses need to be repaired because of the sinkholes.

Coal-mining over the years has changed the locations and drainage system of the underground rivers and springs in the two villages, which caused karst caves to collapse, according to preliminary findings announced by the bureau of geology and mineral exploration in Hunan province.

Lianyuan city and Fukou county sent a team to address the situation. Warning signs and protective fences were placed around the sinkholes. Village officials kept a close eye on the affected area to track the latest developments.

One farming family was evacuated to a safe place. No injuries or deaths were reported.

The coal mine under question is paying compensation to villagers for their losses, including the damaged crops and ponds.
