metals, their mining and extraction technology is very costly. The continuous miner technique, which is also known as room and pillar mining, uses equipment to cut a series of paths, or "rooms", leaving sections of uncut coal approximately 20 feet square to support the overhead structure (also known as "pillars").

8.4 Factors Contributing to Equipment Maintenance Cost in Mines Many factors contribute to the cost of mining equipment maintenance. The major ones are shown in Fig. 8.2 [1]. In the case of equipment design, it is important to note that certain makes and models of mining equipment are designed satisfactorily to facilitate maintenance
Surface mining is a mining operation that happens on ground level rather than in a cave.. Statistically, surface mining is more common and efficient than underground mining operations, though the two are vastly different processes. Surface mining operations uncover roughly 97% of all mined materials, primarily due to the …

underground mining equipment is specialized and expensive. A number of surface mines operate 24 hours/da y and almost 365 days/year in order to use open pit machinery for as many hours as possible, thereby reducing the number of machines required. In contrast, underground operations are often interrupted by the need

Mine safety training saves lives. In 1978, the year the Mine Safety and Health Admin-istration was established, 242 miners died in mining accidents. In 2012 the number of deaths had dropped to 36. Training the people who work in the mining industry – and retraining annually – helps reduce deaths, injuries and illnesses.
