Last month, the state cabinet came out with a new mining policy, aimed to bring further transparency in the sand mining business.
In the new policy, which is aimed to generate revenue of Rs 400 crore, the cabinet had decided to enable the government to grant contracts by auction of mining blocks in strategically established clusters through progressive bidding instead of the earlier process of auction by individual mines.
The policy also mandated geo-tagging of all mines while conducting physical inspections, and boundaries of mines would be checked using coordinates recorded by GPS device.
