Abstract:

Present study was conducted to investigate spoil characteristics under 5-yr old high-density plantations of three native trees (Albizia lebbeck A. procera and Tectona grandis) and one fast growing woody grass (Dendrocalamus strictus) species on coal mine spoils and same age unplanted mine spoil dump at the same area. We examined physical characters such as soil bulk density, water holding capacity, soil texture (sand, clay and silt) and chemical characters such as pH, total nutrients (C, N and P) and exchangeable cations (Ca, Mg, K and Na) in chronosequence of spoil depth (0-50 cm) at 10 cm in

Abstract:

Data on the erodibility of overburden spoils resulting from open-cut coal mining are limited. These data are required to derive parameters for erosion prediction models which can be used in the design of re-formed landscapes after mining. In this study, laboratory rainfall simulation data were used to derive CREAMS (Chemicals, Runoff and Erosion from Agricultural Management Systems) interrill erodibility parameters K and nbov for Central Queensland coal mine overburden spoils. For the spoils studied, K values ranged from 0·0111 to 0·1398 Mg·ha·h/(ha·MJ·mm) and nbov values ranged from 0·0004 to

Abstract:

Coal mine spoils have the potential to create environmental impacts, such as salt load to surrounding environments, particularly when exposed to weathering processes. This study was conducted to understand the effect of physical and chemical weathering on the magnitude, rate, and dynamics of salt release from different coal mine spoils. Five spoil samples from three mines in Queensland were sieved to three different particle size fractions (<2 mm, 2–6 mm, and >6 mm). Two samples were dispersive spoils, and three samples were nondispersive spoils. The spoils were subjected to seven wet–dr

Mining causes massive damage to landscape and biological components of an ecosystem. Due to extensive and unmanaged coal mining in the southern part of Nokrek Biosphere Reserve of Meghalaya, the area has been turned into degraded land since nutrient deficient sandy spoils are hostile for the growth and regeneration of plant communities. Soil is sandy to sandy loam and red, brown to dark brown in colour. The physico-chemical properties of the soil were greatly affected due to coal mining.

Deep coal mining activities in the Ebro Valley, north-eastern Spain, are important elements of the economy. A method for reclamation of high slope (30-56%) spoil banks under semi-arid Mediterranean conditions was assayed using amended mine spoils (with pig slurry and straw) as substrate due to the lack of topsoil. Sixteen experimental plots, divided into 4 sets according to slope aspect, gradient, and length, were established in October 1998. Two types of substrate and 4 types of seed mixes were used.

Abstract One of the legacies of the coal mining industry is the existence of numerous colliery spoil mounds. Run-off waters from some of these mounds result in oxidation of sulphur compounds causing pH to drop to perhaps as low as 2.5. At this pH, mobility for metals increases and it results in destruction of both flora and fauna. In order to reduce acidity, a number of solutions have been investigated with varying degree of success.

Abstract:

During the 20th century, Germany belonged to the world’s largest producers of lignite coal. Approaches for remediation of lignite spoil and overburden material were carried out since at least the last 50 years. Today, results of former remediation can be evaluated by their long-term effects. Coal spoil seepage waters can impact billions of m3 of ground water in involved areas for a very long time horizon (eternity impacts). In the last years our working group had studied especially lignite coal spoil sites in the Lusatia (East Germany) with sandy substrates and faster vertical mass transport p

Abstract:

Single point shovels type furrow openers are simple in design and because of their simple low-cost construction; they are widely used in cultivator for opening the soil. The study was conducted on the soil disruption by tractor operated cultivator type single point shovel to improve soil conditions in sandy loam soil using six types of single point shovels at operational speed (1.53 and 1.81 m/s ) and depth of operation of (0.10 and 0.12 m), respectively. Shovel S5 gave more spoil furrow width, spoil furrow depth, spoil area and trench area compared to the other single point shovels.

Abstract:

In 1993, a field study commenced to determine the impact of vegetative cover and slope on runoff, erosion, and water quality at 3 open-cut coal mine sites. Runoff, sediment, and water quality were measured on 0.01-ha field plots from 3 slope gradients (10, 20, 30%), with pasture and tree treatments imposed on soil and spoil material, and 2 soil and spoil plots left bare. The greatest soil erosion occurred before pasture cover established, when a large surface area of soil (>0.5 plot area) was exposed to rainfall and overland flow. Once buffel grass (Cenchrus ciliaris) colonised soil plots,

Abstract:

Afforestation has been a popular restoration procedure for spoil heaps in the sites affected by coal open-cast mining in the Czech Republic. Forest replantation is a frequent restoration variant when spoil heaps are recovered, but unreclaimed sites are often left to spontaneous succession. Studies on the dynamics of such restored forests are missing, and the evidence of restored forests with respect to their recreation value is also sporadic. To study the dynamics and management of restored forests—both replanted and recovered by spontaneous succession—on spoil heaps, we used a matrix growth m

Abstract:

AbstractThis article describes two methods of showing the distribution of temperature on the surface and inside a spoil tip (coal mine waste dump) located in Wojkowice (in the Silesian Voivodeship). Two deterministic estimation methods were tested, i.e., Inverse Distance Weighting (IDW) and Radial Basis Functions (RBF). According to isotherm maps the highest temperature on the surface of the “Wojkowice” spoil tip was in the NE area, while inside the heap the highest temperature noted was in the SW area. Better results were obtained from the application of the RBF method. A three-dimensional mo
