Methods for assessing mine site rehabilitation design for erosion impact.
March 1, 2000... Introduction Surface mining is a major industry in Australia. Without proper management and design, above-grade waste rock dumps (WRDs) and voids have the potential to cause severe environmental impacts. One such impact is the pollution of...

Medium-term erosion simulation of an abandoned mine site using the SIBERIA landscape evolution model.(Statistical Data Included)
March 1, 2000... Introduction The SIBERIA landscape evolution model has been used as a tool for assessing the impact of erosion rehabilitation proposals for the Energy Resources of Australia (ERA) Ranger Mine after the completion of mining (Willgoose and...

Estimation of erosion model erodibility parameters from media properties.
March 1, 2000... Introduction Early studies by Bennett (1926), Middleton (1930), Baver (1933), and Cook (1936) demonstrated that erosion rates were influenced by soil properties. The initially simple relationships reported by those authors have...

Use of laboratory-scale rill and interill erodibility measurements for the prediction of hillslope-scale erosion on rehabilitated coal mine soils and overburdens.(Statistical Data Included)
March 1, 2000... Introduction In Queensland, the area disturbed by open-cut coal mining exceeds 50000 ha (Welsh et al. 1994), with much of that area required to be rehabilitated. The first step during mine-site rehabilitation is to design a post-mining...

Effects of vegetation cover on runoff and erosion under simulated rain and overland flow on a rehabilitated site on the Meandu Mine, Tarong, Queensland.
March 1, 2000... Introduction Environmental management policy for mining in Queensland (Department of Mines and Energy 1995) seeks 'to achieve: * acceptable post-mining land use capability/sustainability * stable post-mining landform(s), and *...

Impact of vegetative cover and slope on runoff, erosion, and water quality for field plots on a range of soil and spoil materials on central Queensland coal mines.
March 1, 2000... Introduction Draglines are used in most open-cut coal mines in Australia, with the result that landscapes after mining generally consist of a series of parallel spoil piles, with slope angles of approximately 75%. The cost of recontouring...

An assessment of requirements of neutralising materials of partially oxidised pyritic mine waste rock.
March 1, 2000... Introduction Acid mine drainage from sulfidic mine waste rock dumps and open pits is a major concern in the rehabilitation of both active and abandoned mines associated with sulfide bearing ores. Large amounts of limestone are commonly...

Soil stripping and replacement for the rehabilitation of bauxite-mined land at Weipa. I. Initial changes to soil organic matter and related parameters.
March 1, 2000... Introduction Comalco Aluminium Ltd has mined bauxite at Weipa, in far North Queensland, Australia, since 1963, with progressive rehabilitation of mined areas begun in 1966. Early rehabilitation efforts investigated the suitability and...

Soil stripping and replacement for the rehabilitation of bauxite-mined land at Weipa. II. Soil organic matter dynamics in mine soil chronosequences.
March 1, 2000... Introduction Soil organic matter dynamics is recognised as a key ecosystem process regulating ecosystem sustainability (Hart et al. 1990). At Weipa (North Queensland, Australia), routine soil stripping and replacement operations for...

Soil stripping and replacement for the rehabilitation of bauxite-mined land at Weipa. III. Simulated long-term soil organic matter development.
March 1, 2000... Introduction It was not possible to discern the long-term effects of soil stripping and replacement operations on rehabilitated soil and plant systems following surface mining of bauxite at Weipa from short-term experiments (Schwenke et...

Mining disturbance alters phosphorus fractions in northern Australian soils.(Statistical Data Included)
March 1, 2000... Introduction Prior to bauxite mining at Weipa, North Queensland, the native forest is removed and the soil (brown kandosol to an average depth of 60 cm overlying bauxite) is preserved for use in the mine rehabilitation program. The aim of...

Litter cover as an index of nitrogen availability in rehabilitated mine sites.(Statistical Data Included)
March 1, 2000... Introduction The development of mined areas after rehabilitation has been described previously as an artificial succession (Man's and Bradshaw 1982), whereby the goal of rehabilitation is to manage the system in such a way that the effects...

Mineralisation of nitrogen in a chronosequence of rehabilitated bauxite mines.(Statistical Data Included)
March 1, 2000... Introduction One of the key aims for rehabilitation of disturbed land (e.g. after mining, logging, and forestry activities) is maintenance of plant productivity and diversity in the long term (i.e. sustainability, Ecologically Sustainable...

Soil development on rehabilitated bauxite mines in south-west Australia.(Statistical Data Included)
March 1, 2000... Introduction Alcoa World Alumina Australia mines and rehabilitates around 450 ha of the northern jarrah (Eucalyptus marginata Donn ex Smith) forest each year at 2 open cut mines on the Darling Plateau at Huntly and Willowdale 110 and 130...

Soil development of an artificial soil mix: nutrient dynamics, plant growth, and initial physical changes.(Statistical Data Included)
March 1, 2000... Introduction Where the establishment of a self-sustaining ecosystem is an objective of site restoration, areas devoid of soil (such as industrial sites, tailings, and mined land) have specific difficulties that must be overcome. Typically...

Nutrient status of pasture ecosystems established on rehabilitated overburden and topsoil sites in the Hunter Valley, New South Wales.(Statistical Data Included)
March 1, 2000... Introduction Mining removes the vegetation and inevitably leads to the loss of some plant nutrients. This is particularly important where the proportion of the total nutrients in the ecosystem that are contained within the vegetation and...

Waste jarosite and alunite will be ineffective sulfur and potassium fertilisers.(Statistical Data Included)
March 1, 2000... Introduction In the production of synthetic rutile from ilmenite, the last step of upgrading the reduced ilmenite to rutile involves dissolution of iron and manganese in dilute sulfuric acid. This effluent is normally neutralised with...
