Panian mine in Semirara Island. Coal mining in the Philippines has a long history dating back to the 1800s during the Spanish colonization of the islands. The Philippines consumes more coal than it can produce and coal is the main source of electricity. 20% of the country's coal supply is used by the cement industry (in 2005).
By 1800, Britain boasted over 2,500 steam engines, most of them used in mines, cotton mills, and manufacturing factories. These engines fed on coal and, as a consequence of their success, coal mining boomed. Steam engines were also now being used in coal mines in other European countries, notably Belgium, France, Germany, and the Netherlands.
A mining accident is an accident that occurs during the process of mining minerals or metals. Thousands of miners die from mining accidents each year, especially from underground coal mining, although accidents also occur in hard rock mining is considered much more hazardous than hard rock mining due to flatlying rock strata, generally incompetent rock, the presence of methane gas ...

Sharp cutter picks attach to the head and extract coal from the coal seam, working within the machine's minimum and maximum cutting height. Some models have a dual gathering head system to increase development rates. Both single and double cutter head systems lift to reach their maximum cutting height.
Coal and coal gangue are petrogenic sources of polycyclic aromatic hydrocarbons (PAHs), which cause adverse impacts on the environment. Raw coal, cleaned coal, slime, slack gangue, and lump gangue from the Pingshuo No. 1 Coal Preparation Plant, China, were analyzed to determine the concentrations and compositions of 16 priority parent PAHs (16PAHs) and their alkylated derivatives (aPAHs).
