M.Ing. / As of 1991 new legislation demands that all existing and proposed mines have to submit and implement a rehabilitation plan. This plan consists of numerous phases and can cost a fair amount of money that almost none of the mines have budgeted for. During the rehabilitation process the improvement of the ground on, for example, discard dumps or slurry ponds, are not stable or adequate to enable the civil engineer to ensure stability for the new development. This can include a new sports field or low cost housing or just the peace of mind that the dump is stable and looks natural. This thesis will aim to introduce some of the numerous different ground improvement techniques that are available in South Africa and overseas.

M.Sc. / The decommissioning of mines and mining-related activities brings about the onset of rehabilitation. A legacy that most coal mines must address is the rehabilitation of the coal discard dumps that are generated by the beneficiation process of the raw coal. Rehabilitation involves the shaping and covering with a topsoil layer of these coal discard dumps. The topsoil layer is then revegetated to provide a stable form of protection against erosion. Considerations taken into account regarding the rehabilitation of coal discard dumps include the final slope angle, physical constraints i.e. railways or rivers, a source of topsoil and the grass species to be sown. Once the dump has been shaped, capped and seeded, regular applications of fertilizer take place for a defined period of time. This is to accelerate the growth of the grasses, as well as to stabilise the nutrient levels in the topsoil capping. Ingwe Mine Closure Operations (MCO), part of Ingwe Collieries Limited, is the business unit entrusted with the management and successful rehabilitation of Ingwe’s defunct operations. All of the coal discard dumps sampled in this study are found on such defunct operations. These coal discard dumps have been rehabilitated to a very high standard by MCO, and in most cases exceed the minimum requirements stipulated by law and guideline documents. This study and the results obtained from it reflect this. This study investigated, in terms of defined types of cover, whether or not there is a statistically significant difference between the: • six coal discard dumps from which data were collected; • five different defined slope aspects; • two groups of slope angles; and • slope angle and slope aspect in terms of cover. The data collected was analysed statistically, so as to determine whether significant differences (95 percentile confidence level), in terms of cover, exist. The purpose of this was to determine whether or not a preferred slope aspect or slope angle group could be identified for the six coal discard dumps sampled. By identifying a preferred slope aspect or slope angle group, companies could alter the design of operational or defunct dumps so as to maximise these. This would make the rehabilitation of the dump more sustainable and could possibly reduce aftercare costs. Through statistical analysis of the data collected it was determined that: • of the six coal discard dumps sampled, significant differences did exist between some of the dumps regarding basal cover, plant litter cover and bare ground. As each dump is different with its own specific micro-climate, this can be expected. The age of the dumps could also have played a role in terms of development; • of the five different defined slope aspects analysed, no significant differences existed between any of them; • of the two groups of slope angles analysed, no significant difference existed between them; and • no relationship between slope angle and slope aspect, in terms of cover, could be established. The analysis of the data collected was done by means of ANOVA one-way tests, coupled with Post Hoc Tests and Contrast Tables. The results of the statistical analysis were evaluated by the STATCON Department of the Rand Afrikaans University for accuracy. The data and the statistical analysis thereof were found to be satisfactory and correct. Various other statistical analyses were conducted on the data, but the results obtained from these tests were all the same as that of the original data analysis. These analyses included the Univariate Analysis of Variance, T-tests and Mann-Whitney tests.

Thesis is submitted in partial fulfilment for the degree of Master of Architecture to the Faculty of Engineering and the Built Environment, School of Architecture and Planning at the University of the Witwatersrand, Johannesburg, 2018 / This thesis aims to understand the role that Independent Power Producers (IPP’s) can play in the renewal of architectural firms in creating new realities and how these firms can once again become drivers of social change. Kathu (Northern Cape), a steel mining town, is facing the reality that it will have to survive without a mining house and the community funding that results from its operations soon. There are three IPP’s within a 50km radius of Kathu. Under the current funding structure all 3 IPP’s have to contribute to socio-economic development (SED) and enterprise development (ED) within Kathu. According to the Independent Power Producers Procurement Programme (IPPP’s), IPP’s are required to provide 1% of gross turnover to community funds for SED and ED development programmes. Where this funding differs from funding obtained from mining houses is that renewable energy is effectively limitless. Despite IPP’s having a projected lifespan of 20 years they will continue to be redeveloped and upgraded. These upgrades will allow for longevity of revenue, which in turn allows for sustained support for the communities surrounding them. Funding structures that are being used to disseminate mining house funds to the communities are suffering from governance issues. This means that the communities do not receive the most effective or necessary forms of development. Through a new typology of architectural practice, the way these funds are managed and utilised can create better environments for those communities. This new typology of architectural firm must move away from the corporate and profit driven nature of modern architectural firms and more towards a ‘Rural Studio’ model. This is where the primary focus is on the community and how to best serve the needs of the people. In doing so SED projects would be more effective in bringing about social change, creating new realities for communities and drivers of sustainability in post-mining towns in South Africa. / XL2019
