| Description |
India is the leading producer of sheet mica and a
major part of this is exported. Nellore mica belt is the
largest mica-producing area covering part of Nellore
district in Andhra Pradesh, India. As most of the
mines are old and privately operated, they are developed
and operated purely based on local experiences.
In this article, we highlight the problems associated
with the present mica-mining practices in the Nellore
mica belt, and scientific approaches that have been
adopted for fixing different parameters associated
with mica extraction. Based on detailed field study,
geo-mechanical data and tested rock properties,
extensive numerical modelling is done to suggest the
best possible method of mining for safe and sustainable
mica extraction from the area.
