Advantage and dis advantage of mineral resources
Answers
Answer:
The major disadvantages of UG Mining are
Dangerous in nature for the miners. Persons who work in UG mines will be under Continuous danger from Strata ( from collapse from side and roof), poisonous and toxic gases. There will be danger of explosion, fire and also inundation (flooding).
As the working area is limited, high mechanisation is limited. You can not put bigger machine like in surface Mining.
Long gestation period. It took very long time to develop an UG mine before it give full production.
Advantage s of UG Mining
1. Very less land acquisition and RR problem. The land above the mineral property is not disturbed, only small area is required for pit top, offices, workshop etc. Unlike in opencast Mining where all land above the mineral property has to be acquired. This land acquisition is very big task, whether it agriculture land or forest land.
2. The soil and agriculture land is destroyed in opencast Mining. Not in the case of UG Mining.
3. No destruction of Forest and ecosystem is not disturbed.
