  • Gastric cancer in coal miners: an hypothesis of coal mine

    An hypothesis is proposed to explain the elevated incidence of gastric cancer among coal miners. Inhaled coal mine dust, especially the larger particles, is cleared from the lung and tracheobronchial tree by mucociliary function, swallowed, and introduced into the stomach. Organic and/or inorganic materials in the dust can undergo intra-gastric nitrosation and/or interaction with exogenous

  • Coal mining Wikipedia

    Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is called a 'pit

  • Effects of Coal Mining on Environment Term Paper

    Coal is the most important source of fuel. In the process of development, coal mining is one of the major industries, which is contributing towards the destruction of the environment. It causes dangerous damages on water, soil, animals, plants and other part of ecosystem. Coal mining affects the ground water by contaminating it. Contamination will happen when the amount of excess water that is used in mining

  • A new coal mine floor rating system and its application

    01/04/2020· Based on the hypothesis, the quality of the floor was considered to be one of the major parameters in the occurrence of floor heave. Coal mine strata generally consist of multiple units; thus, a rock mass classification appeared to be appropriate for developing simple and practical design methods. Thus, the CMRR was slightly modified to develop a new rock classification system for the coal mine
