Coal seam inclinations) of more than 8 – 20º have in many cases lead to failures of waste dumps (usually coinciding with heavy rains, poor drainage and clay material in the bottom of the waste dump) and therefore modified terrace or even open pit mining methods have to be applied – although these methods are often not financially viable with a low unitcost high volume product such as coal.

Modern equipment and techniques allow opencut mining to around 200m. Many underground coal mines in Australia use longwall mining methods, which enable extraction of most of the coal from a seam using mechanical shearers. The mining 'face' can be up to 250m long.

Coal mining near the surface can disrupt and pollute streams. Underground mining can cause acidic water to leak into streams. If the mine collapses, it can also cause the ground to sink or shift. Safety These plants are quite safe for operators. Coal mining is dangerous for the miners. However, coalmining related deaths have gone down over time.

LONGWALL ADVANCE MINING. An alternative method of mining is advance longwall mining. In longwall advancing, the longwall face is set up a short distance from the main development headings. The gate entries of the longwall face are formed as the coal is mined. The gate roadways are thus formed adjacent to the goaf.

A. Abutment In coal mining, (1) the weight of the rocks above a narrow roadway is transferred to the solid coal along the sides, which act as abutments of the arch of strata spanning the roadway; and (2) the weight of the rocks over a longwall face is transferred to the front abutment, that is, the solid coal ahead of the face and the back abutment, that is, the settled packs behind the face.

Open pit mines can be used in coal mining, and they are used extensively in "hard rock" mining for ores such as metal ores, copper, gold, iron, aluminum, and many minerals. In a open pit coal mine, the pit bottom would be the bottom mined coal seam elevation, since it is usually feasible to extract multiple seams when surface mining coal.
