Advantage and disadvantage of underground (U\G) mines.

A) Advantage of Underground (U\G) mining method.

 

 ·       The land above u\g mines is not disturbed and only small area required at pit-top for office, workshop, winding room etc.

·       The agriculture and forest land not disturbed with u\g mining.

·       There is not much environmental problem such as air pollution, noise pollution.

·       No need to excavate over burden to reach ore body.

·       In u\g mining method does not affected on work by weather.

 

B)  Disadvantage of Underground (U\G) mining method.

 ·       There is roof fall problem hence we require roof supporting material which are costly.

·       Additional material (stowing material) required to fill excavated area.

·       There is problem and danger of gas exposition, inundation and roof fall.

·       In this method required artificial lighting and proper ventilation.

·       High mechanized is not possible.

·       This is costly mining method as compare to open cast mining.

·       Full extraction is not possible mineral is blocked in shaft, pillar, barrier, support of main roadway etc.
