“…In the literature reviewed, annual costs for ventilation and cooling systems start from 20% of the annual energy usage [9], 23% of the operating costs [10], and 25% of the mine's electricity costs [11]. It is thus a significant expense for any mine operation.…”

Abstract. BACKGROUND: Ever deeper mining is exposing workers to increasing heat and humidity, which can threaten their health and safety. OBJECTIVE: The objective of this research is to create a matrix of criteria that will eventually be used to design a personal cooling vest that will meet the needs and wants of miners. METHODS: A literature review was done to identify the constraints and requirements of miners in ultra-deep mining conditions; a field study was conducted in which information was acquired by measurement (temperature, humidity), observation (work rate) and semi-directed interviews of a convenience sample, 20 volunteer participants (age, weight, height, shirt size, personal protective equipment currently worn and opinion about a cooling vest). The data was then structured, compiled and interpreted to create a matrix. RESULTS: Participants were found to be in the > 50% percentile of the population regarding weight and height. All reacted positively to the idea of a cooling vest to help in their work. A matrix containing nine users and seven design-related criteria was created. CONCLUSIONS:The matrix must still be tested as to its validity. Its usage could then be extended to other fields of work in which heat is a health and safety concern for workers.

“…This charge is only applicable if the reactive energy during a 30-minute period is more than 30 per cent of the active energy, which implies a power factor below 0.96 [3]. Reactive energy can be reduced by installing power factor correction systems (capacitor banks).…”

“…Energy is expensive around the world; and in South Africa, electricity prices have increased dramatically in the last decade [1][2][3][4]. This has placed considerable pressure on industries to monitor their electricity consumption and implement initiatives to reduce their electricity costs [4][5][6].…”

The ever-increasing cost of energy puts industries under pressure. Industries are forced to monitor their energy consumption and to manage energy more efficiently and responsibly. Some industrial companies have multiple operations spread out over a wide area, making it logistically difficult to get a holistic view of the company's energy performance. Valuable information is freely available in the form of electricity bills. However, to benefit from the information in the bills, the data should be extracted and analysed, which is a time-consuming process. In this paper, a need for an automated centralised system that extracts and analyses electricity data from bills was identified. The methodology for extracting, organising, and presenting the electricity bill information is explained in detail. The system is implemented for a gold mining company, and the results are interpreted and discussed. It was found that the system is beneficial for companies with many operations. As the number of operations increases, the value of automated bill analysis increases. OPSOMMINGDie kostes verbonde aan elektrisiteit in Suid-Afrika neem vinnig toe en die befondsingshekkie vir energiebesparinginsentiewe verminder. Daarom, met die toenemende internasionale mededinging en operasionele kostes, moet marginale industrieë fokus op energiebestuurstrategieë waar groot besparings met klein kapitaalbestedings verwesenlik kan word. ŉ Behoefte aan ŉ omvattende energiebestuur informasiestelsel word uiteengesit in hierdie artikel. Energiebestuur slaggate word uitgelig en energiebesparinginsentiewe word bespreek. Nuwe fokuspunte wat kliëntbewustheid verbeter en gevolglik die volhoubaarheid van energiebestuuringrypings verhoog word ook uitgelig. Om voordeel te trek uit energiebesparings word egter meer ingewikkeld en gevolglik ly baie kliënte daaronder, behalwe as hulle industriekenners betrek. Hierdie industriekenners vereis egter groot hoeveelhede data om ŉ kliënt se energie effektief te bestuur. Daarin lê die noodsaak vir ŉ omvattende energiebestuur informasiestelsel. So ŉ energiebestuur informasiestelsel is ontwikkel en geïmplementeer vir verskeie industrieë in Suid-Afrika. Data is outomaties ingesamel, geprosesseer, analiseer en voorgehou op ŉ daaglikse basis. ŉ Gevallestudie ondersoek die enorme hoeveelheid data en verslae wat outomaties bestuur word. Dit beklemtoon die behoefte aan ŉ omvattende energiebestuur informasiestelsel.
