Mining experts are gathered in Greymouth to look at the risks involved in the three re-entry options for the Pike River Mine, and 1 NEWS has explained the options using a 3D graphic.
The bodies of 29 men remain in the West Coast mine following an explosion on November 19 2010. Re-entry would allow experts to search for the bodies and gather evidence about the disaster.
The graphic shows the lie of the land above the mine and two distinct areas of the mine underground.
The mine drift, or access tunnel, starts from the entrance to the mine and runs 2.29 kilometres to what's known as the workings.
The workings are where the coal was being extracted and were the last locations of the 29 miners. The workings area contains a network of more than four kilometres of tunnels.
The first re-entry option is going in through the current entrance as it is now, with no secondary exit.
The second is the same but with a large bore hole made to provide a means of escape.
The other option is to create a new two-metre by two-metre tunnel about 200 metres long from up on a hill, to connect with another area for ventilation and a second exit.
Safety is the biggest priority and the findings will be reviewed over the next month.
Baby squirrels in the US state of Wisconsin have been freed after their tails became dangerously tangled together.
They were handed in at the Wisconsin Humane Society’s Wildlife Rehabilitation Centre which worked to save the lives of the five young grey squirrels.
They became entangled with grass and plastic strips their mother used to build a nest.
The squirrels were cut free with scissors while under anaesthetic.
"You can imagine how wiggly and unruly this frightened, distressed ball of squirrely energy was, so our first step was to anaesthetise all five of them at the same time," the centre told the BBC.
Then they began unravelling the "Gordon Knot".
"It was impossible to tell whose tail was whose, and we were increasingly concerned because all of them had suffered from varying degrees of tissue damage to their tails caused by circulatory impairment.
"The creatures will soon be free to resume a tangle-free life in the wild," the centre said.
A Tasmanian mother on holiday in north Queensland's Whitsunday Islands region is lucky to be alive after a shark mauled her leg.
Justine Barwick, 46, was snorkelling at Cid Harbour on Wednesday when the attack happened leaving her with a severe wound to her left thigh and minor wounds to her calf.
Ms Barwick, a mother of two, would likely have bled to death without the quick- thinking actions of people in nearby boats.
In a second stroke of luck a rescue helicopter scrambled to the region was just 15 minutes away from the scene due to an earlier operation they'd been undertaking.
The hovering chopper drew the attention of John Hadok, an emergency department doctor from Mackay Base Hospital, who was sailing nearby and soon joined the effort to save Ms Barwick's life.
Dr Hadok's direction ensured correct first aid was given to Ms Barwick, allowing her to be safely winched into the helicopter.
RACQ CQ Rescue Helicopter crewman Ben McCauley said the doctor and others who gave first aid to Ms Barwick before she was winched aboard had likely saved her life.
"The original first aid was actually really well done," Mr McCauley told reporters today.
"We actually didn't have to do anything with the leg, it was pretty much tourniqueted up, bandaged up and bleeding had stopped. They'd done a really good job."
Although he didn't see the wound, Mr McCauley was told Ms Bariwck had "quite a big chunk of leg taken" and had suffered arterial bleeding.
She also suffered puncture wounds to her calf muscle.
The helicopter then stopped at Proserpine to refuel, allowing blood from a local hospital to be transfused and other medical treatment given.
Just after 8pm Ms Barwick arrived at Mackay Base Hospital where she remains in a critical condition on Thursday morning after overnight surgery.
Her husband Craig is at her bedside.
Ms Barwick works for non-profit Family Based Care in Burnie and had travelled to the Whitsundays on a holiday with her husband and friends.
Family Based Care chief executive Doug Doherty said Ms Barwick and Craig were regular visitors to the popular tourist destination in the heart of the Great Barrier Reef.
"It didn't surprise me, because she is such a fighter, when she was being taken off the rescue helicopter and taken into hospital she was telling them what she was allergic too and still able to give directions," Mr Doherty told AAP.
"That sounds like Justine to me."
A driver in the Waikato walked away "extremely lucky" as their newly purchased turbo-charged car went through a farm fence and over a cattle tunnel, according to police.
The owner felt a wooden fence post brush passed their face after it pierced the car's windscreen in the crash yesterday.
Constable John Keoghan from Waikato Police said the driver of the car only walked away with a sprained ankle.
Mr Keoghan said the driver and owner had only bought the car last Friday. They had saved up for a while to purchase the vehicle and it was their dream car.
They had never owned or operated a turbo, high performance vehicle before.
As they left Te Aroha the gears were changed at high revs on a slightly wet road. The back wheels spun out and control was lost.
Mr Keoghan wanted to share this story in the hope that it makes someone think twice and potentially save someones life "we can only try" he says in a Facebook post.
