Abstract

It is important to assess mining productivity to ensure optimal mining production performance. Mining productivity is achieved through proper management, monitoring and evaluation of invested resources and operations to increase production efficiency. This paper assesses the production efficiency of an underground coal mine called Tatama Mine (TM) by identifying and evaluating the factors that influence production levels using statistical methods. The parameters used include equipment availability, equipment engineering availability, equipment mean time to repair (MTTR) and mean time between failure (MTBF), equipment engineering availability (ENA) and equipment availability (EQA). The results show that the EQA for the continuous miners and MTTR for shuttle cars influenced the production outputs by 77.00% and 96.36% respectively. The MTTR for continuous miners (CMs) influenced production performance by 59.68% while the ENA and MTBF for CMs and EQA, ENA and MTBF for shuttle cars affected production output by < 50%. It is recommended that technological advances should be adopted and integrated into the production system to respond immediately to problems with production units and improve the entire production system. Also, CMs and shuttle cars should be frequently examined within their equipment reliability periods (using their current MTTR values) to maximise their equipment uptimes (MTBF values).
