The mobile app Khanan Prahari, which allows citizens to report incidents of illegal coal mining through geo-tagged photographs and textual information, is a significant step taken by the Ministry of Coal towards curbing illegal coal mining activities. The corresponding web portal called as Coal Mine Surveillance & Management System (CMSMS) has been developed in association with the Bhaskaracharya Institute of Space Application & Geoinformatics, Gandhinagar, and CMPDI, Ranchi.
