Sone of decent private engineering colleges under Btech Mining engineering are listed below.

Malla Reddy College of engineering
Vidya vikas institute of technology
BIAET hyderabad
JNTU Hyderabad.

However all above colleges have very mediocre placements.

You should rathergo for BIT Mesra and ISM Dhanbad which are highly recommended for Mining and Metallurgy Engineering.
