Legal process to file case a against illegal mining in personal land

The Indian railway gave the contract to some contractor to pour the mud near the railway line. So a contractor started mining illegally in my land through JCB machine. To complaint for the same I approached the district magistrate (DM) and gave him a legal notice by mentioning all the activities of illegal mining but the DM was silent on the matter. After that I sent the RTI to the DM and Mining officer for the same. In the RTI, the officer mentioned that the mining is illegal so now I want to know how can I get the compensation in this matter. The land is in the district Etawah, U.P.
