Had the same caution been applied to coal extraction — which was far closer to the surface and caused far more seismic problems — we could have never had an industrial revolution.

The gap has been taken up by large increases in subbituminous coal extraction.

The colliery spoil tips were removed and landscaped and after much opencast coal extraction the area regained its traditional rural appeal from the 1970s onward.

The estimates for global peak coal extraction vary wildly.

Bituminous coal extraction has also been declining since 1990.

The firm uses an extraction method called hydraulic fracturing or 'fracking'.

The most traditional extraction method involves cold processing, in which the beans are steeped in pure alcohol, then filtered and bottled.

Her second project was improving an extraction method for tungstic acid from tungsten ores.

With the ice-water extraction method the resin becomes hard and brittle and can easily be separated.

These natural gas hydrates are seen as a potentially vast energy resource, but an economical extraction method has so far proven elusive.

It can also be used for the extraction of oil, but it gives a poor yield, and the oil has a short shelf-life.

Technologies regarding extraction of oil and coal have been developing for decades, becoming more efficient with each year.

They may also be attractive sites for deep-sea fishing, and extraction of oil and gas and other minerals.

Visitors are permitted to view the process of preparing cinnamon spice and extraction of oil.

Logging and extraction of oil are also developed.

It's nothing more than the air-dried stigmas of the crocus, but it's the painstaking extraction process that pushes up the price.

The strategy was to provide equipment for as much of the extraction process, from first drilling through to fracking, as possible.

Other proposals would see energy companies obliged to build new amenities or infrastructure for residents inconvenienced by the extraction process of 'fracking'.

The extraction process avoids the use of heat (which lowers ingredients' nutrients and efficacy).

The extraction process, which involves injecting water into wells and leaching out the salt as brine, creates large underground caves suitable for secure gas storage.

Campaign groups have sprung up to oppose the industry, which relies on an extraction technique called hydraulic fracturing, or 'fracking'.

Introduced a cataract extraction technique that remained the standard for over 100 years, and many other important surgical techniques such as iridectomy.

For several weeks following the utility's release no success using the author's key extraction technique was reported.

Essential oils are usually prepared by fragrance extraction techniques such as distillation (including steam distillation), cold pressing, or extraction (maceration).

Bioactive molecules are extracted by traditional solvent extraction techniques or by super critical fluid extraction.

Oil and gas extraction dropped by 5.9 per cent from the first quarter, manufacturing slid 1.4 per cent and services dropped 0.1 per cent.

It already has ten gas extraction sites in the county and wells have been operating unobtrusively there for more than 70 years.

Industry insiders expect that shale gas extraction will eventually be approved.

Shale gas extraction typically involves drilling down more than a mile and then turning 90 degrees to drill horizontally across large areas.

Still, agriculture fell 0.2 per cent and production 0.1 per cent, partly thanks to a 2.1 per cent drop in oil and gas extraction.

Outer space required, they argued, a framework for the interoperability of standards, resource extraction proto-cols and some understanding of territorial rights.

The main noise sources were roads, aircraft, land-use conversion and resource extraction activities such as oil and gas production, mining and logging.

They used upland interior regions almost exclusively for resource extraction, although some scholars contest this.

Many areas outside of metropolitan areas, however, are still heavily reliant on resource extraction.

Resource extraction and efficient transportation financed much of the city's growth through the end of the 19th century.

Its widespread use changed dentistry from a trade based on tooth extraction to a profession aimed at preserving the patient's teeth.

Natural tooth extraction, in which patients learn to practise yogic breathing as the dentist grips the pliers?

At first my pelvis area was numb, like a gigantic tooth extraction injection.

Treatment involves repeating the endodontic treatment with improved debridement, or tooth extraction.

Classically, this occurs as a postoperative complication of tooth extraction.
