In a strategic move to combat rampant illegal mining in Ballari and other districts of Karnataka, Mines and Geology Minister SS Mallikarjun recently convened discussions with officials and scientists to implement a cutting-edge geo-fencing project. The initiative aims to meticulously monitor and regulate quarrying activities across various minerals, including iron ore, limestone, manganese, bauxite, gold, and sand, preventing substantial financial losses to the state exchequer.
With an estimated 2,000 illegal quarries in Karnataka, the geo-fencing project is set to commence as a pilot initiative in Ballari, Raichur, Chitradruga, and Davangere regions. Collaborating with the Union government, Karnataka seeks to leverage the success seen in Uttar Pradesh and Tamil Nadu through similar endeavors.
Geo-fencing operates as a virtual perimeter for mining areas, relying on satellite-generated images, remote sensing, and lidar technologies. Google Maps plays a pivotal role in accessing mapping data, ensuring effective monitoring and control of permitted mining sites and the transportation of mining products across district or state borders.
Implementing GPS within a 500-meter radius around permitted mining boundaries, the technology relies on the latest Cartosat images from ISRO-operated optical earth observation satellites. If mining activities occur beyond the permitted boundary, the system assesses soil color to identify potential violations.
The Union government’s Mining Surveillance System (MSS App) acts as a key tool in curbing illegal mining, utilizing satellite-generated visuals to update district headquarters. A comprehensive approach includes attaching a Vehicle Tracking System (VTS) to mining product-carrying vehicles, connecting to the geo-fencing command center for tracking and preventing unauthorized mineral transport.
The integration of Google Maps and drones in the geo-fencing project enhances its capabilities. Plans to incorporate 3D drone surveys for illegal mining detection and revenue enhancement are underway, with the Karnataka State Remote Sensing Applications Center identifying ten districts for pilot projects.
Besides preventing environmental damage by defining specific zones for legal extraction, geo-fencing allows real-time data sharing and alerts for coordinated responses and investigations. Community participation is encouraged, as residents can report suspicious activities through a dedicated platform, complementing geofencing alerts. However, challenges such as technology misuse and false alarms must be addressed, and law enforcement remains critical for a comprehensive and effective strategy against illegal mining in Ballari and across Karnataka.
