Machines and the Coal Miner's Work eHISTORY

Coal mines operated without electricity. Electricity began to be adopted in mining and manufacturing in the late 1880s and the 1890s. (Electricity was first introduced into Ohio's bituminous coal mines in 1889.) The introduction of electricity in coal mines greatly facilitated the

Determination of coal mine mechanization using fuzzy logic

Mar 01, 2009 For these reasons mining engineers are continuously looking for different ways to mechanize mining procedures, especially the mechanization of underground coal mines that provide a large potential for reduced costs, increased safety and improved profitability. Mechanization and automation are changing the way in which ore deposits are being mined.

Adaptability evaluation of fully mechanized coal mining

According to the characteristics of fully mechanized mining technique in thinner middle thick coal seam of Yuanzhuang coal mine, using the principle of fuzzy mathematics to build up the hierarchy analysis model of thinner middle thick coal seam mining technology of geological condition and comprehensive evaluation system.

Fuzzy risk assessment for mechanized underground coal

The proposed method is a more realistic evaluation of the risks which may be available in mechanized coal mines in Turkey. In this way, risky situations and operations in mechanized underground coal mines have been determined by expert knowledge and engineering judgement in linguistic forms.
