The New Usage Of Fracking From Mining Specialist

Fracking can be practised safely in New Zealand

, with huge benefits, a mining and resource expert has argued.The controversial process of pumping water and chemicals into rock to release oil and gas locked underground has caused environmental concerns.Yesterday, the Parliamentary Commissioner for the Environment launched an official investigation into the practice.Bernie Napp, a senior policy analyst at Straterra which represents the country"s mineral sector welcomed the enquiry as an opportunity to "lay this controversy to rest"".He told Newstalk ZB today that fracking could be practised safely and if done so, could have huge benefits for the company, the Crown and the economy.Mr Napp described the ongoing debate as "mired in confusion""."Sure, if you are going to be pumping liquids underground and shattering rocks at depth you"re going to create shockwaves that are going to trip a seismic detector, but the amount of energy involved is 1000-30,000 times less than anything remotely resembling an earthquake that you and I would know about."So the risk of earthquake is a red herring in this debate.""The practice has been used in Taranaki for 20 years, and the Greens have called for a moratorium while further investigations into the environmental issues take place.Parliamentary Commissioner for the Environment Jan Wright has been looking into the controversial issue, and yesterday announced she was stepping that up to a full investigation."The work that has been done by my office thus far shows a substantive case for an official investigation under the Environment Act,"" Dr Wright said."Over the next few months my staff and I will conduct this investigation and produce a report to Parliament.""Ms Wright said she recognised that the issue was "hugely contentious"", and she hoped to have the report completed this year.American geophysicist Michael Hastings said fracking caused "micro earthquakes"" but they could typically not be felt on the surface and there were no long-term effects from the process."The typical earthquakes that are produced on the richter magnitude scale are magnitude zeros to minus ones or minus twos in size but they can scale up to magnitude ones and twos dependant on the type of formations, the pressures, the pre-existing stress conditions in the bore holes and in the formation.""Energy and Resources Minister Phil Heatley said he believed the practice had been undertaken in New Zealand safely, but the enquiry would enable the Government to move forward with confidence.Mr Heatley said the Green Party"s environmental concerns were based on historical, overseas research, and a moratorium was not necessary.Green Party co-leader Russel Norman said his party wanted a moratorium."The problem with fracking is that internationally it"s been found to have caused water pollution as well as air pollution,"" he said.As the professional manufacturer of complete sets of mining machinery, such as Flotation cell,Mobile crushing station,Wet magnetic separator, Henan Hongxing is always doing the best in products and service.China cement mills:http://www.crusher-machine.com/23.html Cone crusher supplier:http://www.crusher-machine.com/4.html
