One of the major benefits to open pit mining is the increase in efficiency over deep-shaft mining techniques. Because mining occurs at the surface, no space restrictions from narrow tunnels and shafts affect the rate at which ore can be extracted.
The planning of an open pit mine is, therefore, basically an exercise in economics, constrained by certain geologic and mining engineering aspects. A bench may be defined as a ledge that forms a single level of operation above which mineral or waste materials are mined back to a bench face.

Underground or “deep” mining consist mostly of two methodsroom-and-pillar and longwall mining. In room-and-pillar, coal deposits are mined by cutting a network of “rooms” into the coal seam and leaving behind “pillars” of coal to support the roof of the mine.
advantages of cast mine Surface mines offer advantages and disadvantages when compared to underground mining. Amongst the advantages are that it is cheaper, can recover more of the resource (usually up to% within the mining excavation), is safer and can use larger-scale mining equipment offering higher production rates.

Advantages Underground mining (as compared to open pit exploitation) allows a mine operation to be largely 'hidden' having only adits or headframes protruding above the surface. This enables the land above the zone of mining to be reclaimed for other uses, after the mining has ceased, so much easier than in the case of an open pit.
pillar mine, several stages of mining occur simultaneously in different rooms. A final phase of mining termed “retreat mining” may be performed to recover additional coal by extracting pillars and allowing the roof to fall.
