Increasing the production rate and minimizing the related costs, while optimizing the safety measures, are nowadays’ most important tasks in the mining industry. To these ends, mechanization of mines could be applied, which can result in significant cost reductions and higher levels of profitability for underground mines. The potential of a coal mine mechanization depends on some important fact...

Present Federal regulations which specify maximum instantaneous circuit breaker settings for the short-circuit protection of coal mine trailing cables are discussed. Characteristics of mine power systems, which limit short-circuit current in dc trailing cables and minimum expected short-circuit currents for dc 300 and 600 V trailing cables, are analyzed. New maximum instantaneous circuit breake...

The Itai-Itai disease case is one of four major pollution-related lawsuits occurring in Japan after World War H. This paper, which is based on investigations of the pollution source, the Kamioka mine, considers (1) the history of the disturbances to the environment caused by the Kamioka mine; (2) the Itai-Itai disease suit; (3) the pollution nprevention measures and methods of the Kamioka mine ...

water has an important role in creating pollution problems in the mining regimes influencing the surrounding surface environment. the purpose of this study is to make an assessment of groundwater quality in an underground mine site in portugal with a view of determining the pollution potential of groundwater. in the corresponding surface area of this underground mine, intersections of fou...

At present, the frequent occurrence of coal mine accidents in China is a key concern field safety. Although accident rate decreasing due to progress technology and improvement management, there still lack comprehensive evaluation role various factors mine. Therefore, purpose this study establish game theory combination weight-TOPSIS model based on analysis affecting The combines weights obtaine...

This paper presents a comprehensive quantitative approach for managing safety in coal mines with multicriteria decision-making model by using fuzzy mathematics. We develop set of factors that affect the management mines, including ventilation, mine roof, and temperature. The also include dust, mining gas, water. Other are equipment reliability, explosive risk equipment, maintenance staff operat...

The United States National Institute for Occupational Safety and Health, through an informal partnership with industry, labor, and the United States Mine Safety and Health Administration, has developed and tested a new instrument known as the Personal Dust Monitor (PDM). The new dust monitor is an integral part of the cap lamp that coal miners normally carry to work and provides continuous info...

In recent years, the micro seismic monitoring technology have the widespread application in Chinese reservoir geological activity monitoring and mine safety monitoring. The effect of micro seismic monitoring technology is very good. However, in the study of micro earthquake, Chinese research started late relatively with foreign. This paper summarizes the current Development status and the appli...
