Beijing: Twenty-two gold miners have been trapped underground for nearly two days after an explosion in a mine under construction in eastern China.
The blast occurred on Sunday afternoon at a mine in a town near Qixia city, Shandong province, Yantai city authorities wrote in a social media post.
The explosion badly damaged the exit ladder from the mine and the communications system, so authorities could not contact the trapped miners, the statement released late Monday said.
Authorities have sent rescuers to the mine, which is owned by the Shandong Wucailong Investment Co. Ltd.
Mining accidents are common in China, where the industry has a poor safety record and regulations are often weakly enforced.
In December, 23 miners died after being trapped in a mine in the southwestern city of Chongqing - just months after 16 others died from carbon monoxide poisoning after being trapped underground at another coal mine in the city.
