could happen and, as late as tomorrow - An attempt to save Pike River to 29 miners trapped underground since an explosion at the mine yesterday afternoon, according to air quality tests.
"Up to safety standards are met, we will not speculate,
"It would happen at night, it could happen in the next hour," Tasman District Police Commander Gary Knowles said at a press conference.
Rescue teams were ready to go into the pit at any hour of the day, he said.
Knowles said earlier that four of the air quality tests had been completed removed from the gallery guy.
The tests were to determine the composition of air in the Pike River mine was safe enough to move for a rescue team, but have delivered, police said.
Police still refuse to save the team kick off.
officials fear could trigger a half-life action and explosions will not be allowed to move a team to confirm the test results indicate that the combustion is unlikely.
The police hold another press conference tomorrow at 8 clock.
PM says global support "enormous"
Prime Minister John Key said that everything would be done to ensure the 29 brave men "were from the mine.
"This is a time of enormous fear and anxiety for the families ... our hearts and thoughts are with them."
He said that concerns raised were pouring from all over the world in the "big" numbers.
"Prince William personally sent me an email saying his heart and thoughts are with the miners."
The big problem is the rescue of trapped in balancing the safety of rescue workers, he said.
"It is a difficult time for everyone, but we are determined to get the men out alive."
Pike River CEO Peter Whittall said special test equipment flown to the contamination problems.
"Right now we have had [gases] from the mountains have to Rapahoe, a small town is just along the coast to fly, analyzes the gas," he said.
"Previously, one of the topics was a gas discharge and pollution to do so, we, this is the beginning of a gas chromatograph.
"Once we did that we can gas bag samples to the site easier, faster and more reliable," said Mr Whittall.
Whittall also noted that there is only "a few hundred meters away from mine way."
"So when the rescue workers go ... they will be looking to come out of the tunnel to the pit bottom area near where our axis and a fresh air base and from there they can be a search and recovery of the rest of the my device.
Whittall said that it was not a large area and the men close together, even if they work in separate rooms.
Safety of the rescuers essential
Pike River chairman John Dow said it would not be a rescue attempt to ensure my officers, were it to make sure the inside
"They did not send rescue teams underground to ensure that the environment that they send.
"You have to know what caused the mix of gases in the mine air, lest they run the risk of another explosion, which could endanger the lives of aid workers and placing the lives of the miners safely underground," he said.
"We have a sense of what was the air quality as last night, but there are concerns with the surface of the air can be mixed from the shaft, because we were only to receive a sample from the top of the ventilation shaft."
Kokshoorn "misunderstood by the media"
Grey District Mayor Tony Kokshoorn said around noon that a rescue attempt would be made "shortly", but Dow said he had "understood by the media wrong."
Energy Minister Gerry Brownlee said he was not aware of where everything is clear for a rescue attempt.
"In principle, the position was taken that I know with the people on the job site when they do something, they let mine," said Mr. Brownlee.
"I do not know where he (Kokshoorn) his information from."
"The weather here is incredible. I am the door of the building I'm looking for and it is very low clouds, so I surprised if that is true would be."
The mine rescue team had already experienced a briefing as they prepare for the mine.
Waiting Game
As rescuers waited for the green light to the affected land mines, Kokshoorn hung on hopes that the 29 miners trapped underground are found alive, but admits that "every hour that goes by, it is more dire."
"We are realistic. There has been a serious accident," he said.
"It's chaotic at the moment, but what is frustrating not give rescuers"
Anxious families gathered to hear information about their missing relatives, desperate.
While many of the miners is believed that the local population, a number of prisoners, probably from South Africa, Australia and the United Kingdom,.
Destroyed Community
Kokshoorn said the community was "grieving hit".
"One of my Council for a young man, the West Coast Rugby League Player of the Year last week got down there, a local host .. - His son is down there"
A father of five, was also mentioned as one of the missing men. The youngest person is a 17-year-old wizard, and the oldest a 62-year-old man
Pike River Coal CEO Peter Whittall said at a press conference this morning that concerns remain over the air and explosive gases in the mine.
"In six to eight hours, we have enough analysis of whether the rescue team can go underground."
He also assured family and friends of the trapped miners by the company, every person and technically possible to restore them.
"Our focus for the next 24 hours, Rescue and Recovery. Rescuers before we ensure that the environment is stable," said Whittall.
Whittall said damage to the upper part of my shaft meant by the explosion: "We can not just samples."
"The only way we determine what is happening underground, can monitor the air on the ground."
"We can not tell about the absolute quality of this so we do not risk sending someone in the mine."
"We are, if we bag a few samples, we can save some background should get confident."
Dangers that the trapped miners have to air pollution, high methane, carbon dioxide treat high and low concentrations of oxygen.
"It's an underground base of fresh air. One of the miners went before it came out.
"It could well be that people underground, but right now we do not know," said Mr Whittall.
Specialist gas testing equipment was flown to Australia in the night.
We will bring these boys home
Tasman District Commander Superintendent Gary Knowles expressed strong determination, the men of the Pike River mine to get news conference this morning.
"This is a search and rescue mission is," he told the media, "and we go to these guys at home."
The police have confirmed 29 men between 17 and 62 years trapped in the mine at the age of 13, including 16 employees and contractors Pike River.
Family Support
The message is send Whittall families and friends of the trapped miners is that the disaster "a common experience."
"I know all the men I have employed all the men. It is much more of a kinship and brotherhood in the mining industry," he said.
"When I look down the list [of prisoners] I see the faces of everyone on the list," he said.
"It is a brother of the person who got out, it is a son of one of the underground mining industry officials. They are men who know all the room."
"I assured them we are doing everything possible and technically feasible to recover from her family and friends."
"The families are angry very much. No knowledge is a bad thing in these situations. It was very intermittent knowledge come through in the night."
All survivors have been reported, he said.
My integrity
Whittall stated that it was unlikely that the explosion would be a collapse in the mine where 29 miners were missing caused.
He expects the mine to maintain structural integrity through the design and materials.
"Mines are generally not damaged the roof, except wood attributes that can be knocked out," he said at a press conference this morning, "we do not do that in mine."
"We have got very strong roof, everything is completely screwed and I would think it is unlikely that an explosion actually saying to a large extent [my tunnel damaged," said Whittall.
Officials remain about the possible levels of methane in the mine affected.
Mr Whittall said they were nothing of the dangerous conditions in the mine on Friday, adding that the miners have a device that they can oxygen from 30 to 60 minutes of fresh air.
Chile offers hope for redemption
Families gathered outside the Pike River Coal offices in Greymouth this morning for the latest news of 29 trapped miners heard.
Looks tired and frightened, the family heard a briefing from Pike River Coal and rescue services are unable to imagine the mine after the explosion yesterday afternoon.
Tony Kokshoorn been greeting each family with hugs. He said the successful rescue of Chilean mines gives him hope.
"We remember the Chile mine recently that every miner came out. In this moment we are hanging up all hope, just as they did.
However, said Mr Kokshoorn a quick rescue was unlikely.
"Rescue teams are doing everything they can, but this is a very slow recovery."
Aid workers still waiting for the all-clear before they build up gas in the coal mine.
Two miners
Nothing was heard from the men deep underground after the explosion last night.
The alarm was struck, when my electrician Russell Smith, 50, a power failure studied at 15.50 clock.
He discovered loader driver Daniel Rock House, 24, is from his broken machine.
The two men who were employed at some distance from the rest of my staff, escaped through a service portal and walked two miles from a valley to the emergency services immediately.
The couple had severe injuries and were taken Grey Hospital in Greymouth.
"One of them talked about the fact that the ground being beaten. He thought he was knocked unconscious by the explosion," said Mr Whittall.
Both men were working alone at the moment and one of them was driving a vehicle about 700 meters in the pit.
The other was a few miles, Mr Whittall said.
Mr Whittall said the two men were "shocked, hurt and confused" and "has a lot for one of the men to explain what happened," said Mr Whittall.
Mr. Smith was home last night, but his partner, Donna Ryan, said he was unable to speak.
"We are so relieved. He's just come home and rest in bed."
Christchurch born Mr Rock House, 24, has a 3-year-old daughter got married and worked for Pike River Coal since June 2008.
One of the miners missing Grey District Milton Osborne.
His son said last night the family waited for news. "They are not. We have not heard anything."
Local knowledge
West Coast veteran journalist Paul McBride, 56, of the Greymouth Evening Star, said that after looking at the damage he captured on film: "I would say that the result will not be good."
The mine entrance looked "completely normal", but the escape portal showed clear evidence of a "free fire and explosion hazard.
McBride surveyed the area from a helicopter about to set up a no-fly zone.
Prime Minister John Key said last night the Government would be required to give the miners and their families to support.
Greymouth High School principal Jim Luders was waiting for a clearer picture before the call of leaders together to discuss who would be among his disciples have advice.
He said 25 families with school-age children who have connections with mine.
