Abstract

:With the current state of affairs, open-pit mining continues to play a significant part in the mining industry and is occasionally brought back into use. The ownership of minerals inside open-pit mining is growing at a steady rate year after year. This is the result of developments in open pit machinery production that have occurred at a rapid pace. An boom in design has occurred in the realm of equipment, which has led to the creation of machines that were previously unimaginable in terms of their scale and output capability. To get the highest possible return on investment per unit, the primary focus of the initial capital expenditure in opencast mining is on equipment for excavation and transportation. This is done with the intention of maximizing the return on investment. Over the course of the past few years, mine management has realized that it is becoming increasingly challenging to recover operating time that has been wasted due to machine faults and idle period. It is possible for HEMMs to lower output, productivity, and expenditures, which ultimately leads to a loss of income when they are not employed correctly. Consequently, in order to achieve cost-effectiveness in transportation and excavation activities, it is required to do frequent evaluations of the performance of the equipment. The Gopinathpur mine in the Mugma area and the Jeenagora mine in the Lodna area are both owned and operated by Eastern Coalfield Limited. The objective of this study was to ascertain the percentage of shovels, dumpers, dozers, and other heavy earth moving machines (HEMMs) that are available and in operation at both mines. Bharat Coking Coalfield Limited, as well as to conduct research into the elements that contribute to the enhancement of the equipment's overall performance.
