The coal mining industry is a major contributor to the Indian gross domestic product and employment. Unfortunately, in recent past the productivity of Indian coal mining industry was not satisfactory. In India, productivity movement has made its impact on both manufacturing and service sectors, but the key area, i.e. coal mining industry has been overlooked right through the past two decades. This paper is based on a case study on productivity measurement; conducted at an opencast coalmine located in Jharia coalfield. The mine is using shovel-dumper combination for wining coal. The study covers the computation of partial productivities as well as total productivity of the mine. The total productivity highlights the productivity status of the mine at an aggregate level whereas partial productivities highlight the efficiency in the use of various resources. A statistical analysis among the different productivity indices has been carried out to identify the criticality of different input factors. Accordingly appropriate strategies can be devised for improving productivity of the mine.
