Abstract:
An exploratory survey was undertaken in order to explore the underlying causes of bankruptcy in junior mining companies operating in the Witbank region of Mpumalanga Province based on data gathered from 120 highly experienced employees of junior mining companies operating at Witbank. Perception on barriers to productivity in junior mines was measured based on a scale introduced by Henisz, Dorobantu and Nartey (2014). Data was gathered on 24 socioeconomic variables. Data was analysed by performing logit analysis. The key finding of study was that 74.17% of respondents believed that their mines

The concentration of mercury vapour in ambient air is routinely determined using specialised instruments.As an economical alternative, actively pumped Hopcalite sorbent tubes can be used to trap atmosphericmercury, which is subsequently analysed by cold vapour atomic absorption spectroscopy. Plant materialsare also readily available in most regions and can be analysed to obtain information on time averagedatmospheric mercury levels.Lichen and tree bark samples were collected in the cities of Pretoria and Witbank, dried and acid digestedwith subsequent cold vapour atomic absorption spectroscopy

Abstract The trace element data pool for South African coals is limited. However, certain elements are reported as occurring in considerably higher concentrations than global average values. These elements include chromium (Cr), as well as manganese (Mn), cobalt (Co), and molybdenum (Mo), with Cr showing the most consistent enrichment. The aim of this study was to investigate the occurrence of Cr in South African coals sampled from five coalfields, and to assess the possible source of Cr.

Abstract The early Permian represents a crucial period of climate change in Gondwana. This climate signature is captured in the palynological record that represents the floral assemblage of the region. Palynofacies analysis of the No. 2 Coal Seam of the Highveld Coalfield provides a high-resolution picture of this climatic shift, as well as detailing the vegetation patterns and local environments. Core samples taken from two localities were studied with respect to the characteristics of the plant debris and the palynomorph assemblages to differentiate between regional and local signatures. At

It presents a significant pollution hazard. Discard coal has a usable carbon content that can be used in the generation of power through the application of fluidized bed combustion technology. The objective of this study was to evaluate its potential as an economically viable fuel source for generation of electricity at the Witbank coalfields. This study was motivated by

Abstract:
Coal deposits serve as important archives of palaeoclimate change. Palynomorph assemblages reflect the composition of the parent plant communities which are in turn controlled by the local environment and regional climate. Palynofacies can also be used to further interpret the depositional environment and transport mechanisms. In Main Karoo Basin, the Permian Ecca Group hosts economically important coal deposits within the Witbank and Highveld Coalfields. The most significant deposits are located in the Artinskian/Kungurian-aged No. 2 Coal Seam. The post-glacial fluvio-deltaic deposits repres

In certain coal seams the ash fusion temperatures drop well below this optimum temperature, leading at times to problems in the user industry. Ash fusion temperature which is the temperatu

Thus there is a demand for clean, unpolluted water to be in substantial supply. There is growing awareness worldwide of the environmental legacy of coal mining activities that have been undertaken with little concern for the environment (EMCBC, 2001). Coal mining by its nature consumes, diverts and can seriously pollute water resources (Miller, 1999).
