A total of 18 miners injured in a coal mine blast which killed 104 in north China's Shanxi Province were doing well in hospitals, sources said on Saturday.

Four seriously injured miners were being treated in Linfen City Hospital while the others were in hospitals in Hongtong County.

They all showed symptoms of carbon monoxide poisoning, such as headaches, fainting and lack of strength, according to doctors with Hongtong County Surgical Hospital which admitted six of the miners. They have been recovering well after treatment, the doctors said.

A gas explosion happened at 11:15 p.m. Wednesday at the Xinyao Coal Mine, a village-run coal mining venture in Hongtong, Linfen City. A total of 15 workers either escaped or were rescued later. A total of 104 miners have been confirmed dead.

"I feel much better now after treatment in the past two days," said Yao Liujie, a 21-year-old miner from southwestern Chongqing Municipality.

Police have detained 33 people who are alleged to be relevant to or responsible for the fatal gas explosion. The Ministry of Public Security issued a class-B arrest warrant for the owner of the mine. Among those detained are the mine's manager Gao Jianmin and its legal representative. Wang Hongliang.

Compensation discussions with the families of the 104 dead miners are under way, a local official said Saturday.

"Given the relatively large number of victims, a considerable sum of money is needed according to current regulations," said Jin Tingrui, head of the publicity department of Hongtong.

He said relevant government departments would raise money from various channels for the economic compensations.

Jin said the Hongtong government was writing to families of the victims offering its condolences.

The cause of the blast is still being investigated.
