Rescuers have not given up hope 
of finding 12 miners alive after they were trapped by flood waters at an 
underground coal mine in Henan Province on Monday.
New water gushed in at 300 cubic metres per hour yesterday, making rescue 
efforts at the Chaohua Colliery in Central China even more difficult, said 
officials with the State Administration of Work Safety (SAWS).
The mine, belonging to the Zhengzhou Coal Mine Group, initially flooded on 
Monday.
Since then, rescue teams have been attempting to locate the trapped miners. 
They have so far failed to find any survivors, SAWS officials said.
"Efforts will not be suspended if there is the slim hope that they are still 
alive," said Song Guangtai, vice-director of provincial colliery safety bureau.
After pumping out water and silt, rescuers had made their way 840 metres down 
the submerged shaft by Monday afternoon, Song said.
However, a Xinhua report noted Monday that rescue efforts were temporarily 
halted due to further flooding in the afternoon.
Rescue efforts are now in a "crucial and difficult" period as six rescue 
teams are working against the clock to get oxygen into the shaft.
The fate of the missing miners remains unknown, said a Zhengzhou Coal Mine 
Group spokesman.
Investigations are under way to establish the causes of the incident, SAWS 
said.
It occurred just one day after another coal mine gas explosion killed six 
miners who were working underground, said SAWS officials. The blast took place 
at a small, private colliery in Jidong County, Jixi of Northeast China's 
Heilongjiang Province.
At least 10 coal miners were trapped underground early on Saturday by the 
explosion.
Liu Shanfu, 36, a survivor, recalled that he and two other miners left the 
shaft at around 5 am. 
They were 50 metres away from the mouth of the shaft when they heard an 
explosion underground and saw black smoke rising.
The blast occurred at Hada village of Jidong County when an unknown number of 
miners were underground.
The owner of the mine fled after the accident. Rescue work is continuing.
Henan has been the scene of several severe mining incidents in recent years 
due to ignorance of work safety, experts said.
For example, a gas explosion occurred on November 22 in Ruzhou city, causing 
the death of 22 people.
With a deposit of 100 million tons, the State-owned Chaohua coal mine had 
been open for about 11 years with an annual output of 2.2 million tons, 
according to Hu Dejin, who heads the colliery.
A local newspaper described it as a modern, fully automated operation.
According to SAWS statistics, 963,976 incidents -- such as traffic accidents 
and mining tragedies -- occurred last year, killing 136,340 people.
That represented a fall of 10.5 per cent and 1.9 per cent, respectively, 
compared to 2002.
