Legal  Reforms  as  a  Tool  for  Sustainable  Development  in  Former  Mining  Communities:  A  Case  Study  of  Kabwe  Lead-Zinc  Mine,  Zambia

The study employs a multi case study analyses from the three mining communities. Proportionate sampling and purposive sampling techniques were applied in selecting the number of participants used in this study. The chiefdoms were grouped into two neighborhoods (Management staff and community stakeholders). The study found out at communities’ levels that companies have been responsive to their host communities to some extent, by contributing to socioeconomic development at certain level through the use of CSR policies. Their contributions included jobs creation and employees’ upgrading and; infrastructural development such as, constructions of housing, schools, clinics, feeder roads and; offer scholarships to school going youths, and support agribusiness in the various communities from the mineral proceeds. There are also indications that developmental projects across the three mining communities are in some way benefiting some stakeholders or locals as part of the mining companies’ contributions towards attaining sustainable development in the affected communities. On the environmental, the study revealed that organisations were set up to handle environmental issues in the three communities. And, there have been some amount of compensation given for resettlements and crops reparations. Nevertheless, communities were not total involved on decisions affecting major environmental issues.

Thickened Tailings

Deep cone thickener (DCT) is key equipment in cemented paste backfill (CPB) technology. However, rake blockage occurs frequently in DCT during the dewatering process of the unclassified tailings being thickened from dilute slurry to thickened tailings or paste. Rake blockage has disastrous effects on the CPB operation. In order to investigate the influencing factors of rake blockage in DCT, a mathematical model of rake power in DCT was developed. In addition, stacking mud bed (made of thickened tailings) from the DCT in Huize lead-zinc mine (HLZM) in different rake blockage accidents was sampled and tested to investigate the effect of tailings characters on rake blockage. Results indicated that the concentration of the mud bed and the friction between the mud bed and the cone wall contributed to the rake blockage. The concentration and friction were influenced by the high content of coarse particles in the mud bed. Moreover, activating devices for bed mud, as the corrective and preventive action, were developed to prevent the rake blockage, which was valid in HLZM.

This paper describes a case study of surface subsidence in the Hongling Lead-Zinc Mine. Hongling Lead-Zinc Mine is located in Inner Mongolia, China, about 240 km away from the border between China and Mongolia. There is a batch of outcrops of the near-surface thick steep-dip metamorphic orebody. The large-scale surface subsidence induced by underground excavation has brought some impact on the safety of herdsmen and their daily husbandry activities nearby. The requirements of reclamation for subsidence areas in the relevant laws and regulations, raise enormous pressure and risk on safe and economic operation. In this paper, a 3D numerical model of this mine was built by 3DMine and FLAC3D to analyse the excavation procedure and mechanism. The results of the simulation were in good agreement with the field subsidence data collected by satellites and unmanned aerial vehicles from 2009 to 2019. The analysis showed that the current mining method—an integrated underground method of stoping and caving—accelerated the surface subsidence, and some measures of monitoring, controlling and management were expected to take in order to improve economic and ecological benefits.

This paper addresses the fields of social and service design in development contexts, practice-based and constructive design research. A framework for social design for services will be explored through the survey of existing literature, specifically by drawing on eight doctoral theses that were produced by the World Design research group. The work of World Design researcher-designers was guided by a strong ethos of social and service design for development in marginalised communities. The paper also draws on a case study in Namibia and South Africa titled ‘My Dream World’. This case study presents a good example of how the social design for services framework functions in practice during experimentation and research in the field. The social design for services framework transfers the World Design group’s research results into practical action, providing a tool for the facilitation of design and research processes for sustainable development in marginal contexts.
