Mathematical Modelling

Manual loading is one of the primary activities and consumes a good amount of time in the Coal mine. With formulation of the mathematical model, improvements in the present method of manual loading which can conserve human energy besides increasing the productivity and reducing the time required. Some of the variables used to formulate this model are (1) Environment of working area such as illumination, ambient temperature and air circulation facility around the manual loading coal mine work station, (2) Anthropometric data which include the ergonomic aspects and (3) Tools used by miner for manual loading operation which include geometric dimensions of tool, based on the data collected of these variables, a mathematical model is formulated.
