Open pit mining is the process of mining a peat deposit by means of a deep pit excavated using one horizontal bench. One of the challenging problems for surface mining operation optimization is

Peat itself is a valuable resource both as fuel and as a horticultural growth medium. More minor uses include use as a health product for bathing (known as peat balneology), and as an absorbent in nappies (diapers) and sanitary products. Peat extraction inevitably results in a large-scale change in the nature of the peatland.

The peat's geochemistry has thus been influenced by regional mining, forestry, and agricultural activities, creating a strong social imprint. Collectively, these results reveal a long-standing human influence on the ecosystem of the Caroux that has existed for at least 1900 years and has become stronger over the last 200 years.

Runoff water quality from a peat mine was studied during 1995 and 1996 in Central Finland. Water samples from three drained sub-catchments and groundwater were analysed for all the standard physio ...

Finally, thanks goes to my friends, Petteri, Cintia and Bryan and my parents and brother, for their support and encouragement. Thank you all very much :-) Lund in November 1997 …

There is an international call to recognize the true ecological value of peat and to work towards comprehensive protection of peatlands. The science has spoken. This outdated …

Mining alters the physicochemical properties of peat, increasing the pH and amount of humified materials by exposing highly decomposed peat, and it causes nutrient deficiency for the microorganisms by removing inorganic compounds (e.g., P, K, and Na); this, in turn, exerts a response in the methane-cycling microorganisms with …

Oil sands deposits accessible by open-pit surface mining cover about 475,000 ha of boreal Alberta, 99% of which is already leased ().Currently, 10 mines have government approval to operate, covering about 167,044 ha ().This is a conservative estimate that excludes the pipelines, roads, seismic lines, and other infrastructure that support the mines.

Our resources share the knowledge gathered by IUCN's unique global community of 18,000+ experts. They include databases, tools, standards, guidelines and policy recommendations.

Peat amendments enhanced the leaching of As from gold mine tailings. Amendments of 5% peat promoted As(V) leaching, whereas 10% peat increased As(III) leaching. As(III) was predominant at ≥20 mg L −1 dissolved organic C from peat. Mine drainage treatment sludge could decrease As concentrations by 65 to 80% in tailings' …

Peatlands are wet environments, so the mining of peat may affect the quantity and quality of both surface and ground waters. The principal effects on surface water are impacts on …

(a–c) Illustrate the impact of mining (drainage with the top peat layer removed) on a natural peatland and the response of restoration (rewetting and the establishment of a Sphagnum moss layer).

Many countries have strict rules when it comes to mining peat moss. For example, any peat harvested in Canada is carefully analyzed first whether it has any long-term effect on the environment. …

The recent development of peatlandrestoration activities indicates thatmodern peat mining techniques seriouslyhamper the natural capacity of bogecosystems to regenerate after adisturbance.

Question: Which restoration measures (introduction of donor diaspore material, application of straw mulch, alteration of residual peat depths) contribute to the establishment of a fen plant community on minerotrophic surfaces after peat mining? Location: Rivière-du-Loup peatland, southern Québec, Canada at 100 m a.s.1. Methods: The effectiveness of …

When mining projects or other developments lead to the draining of peatlands, the peat dries out and becomes more susceptible to fire, which can release huge amounts of greenhouse gases. These fires …

Peat that's burned for energy is a major greenhouse gas emissions source in Finland, which aims to become net zero by 2035. Peat mining is also a leading cause of habitat loss in the country. Tero Mustonen is the 2023 winner of the Goldman Environmental Prize for Europe for his efforts to stop peat mining and joins Host Steve Curwood to …

In Canada, by contrast, peat isn't used as a fuel, and its sheer acreage in less populated areas works in favor of its mining. Canada is the second-largest country on Earth and has 25 percent of ...

Soil hydraulic conductivity of the drained sites (median hydraulic conductivities: 3.3 × 10 −5 m/s, 2.9 × 10 −8 m/s and 8.5 × 10 −8 m/s for the forests, the cultivated site and the peat extraction area, respectively) was predicted better by land use option than by soil physical parameters. Detailed physical measurements were ...
