Mine safety exemptions limit Code application, while notice duties and government override powers remain in place. The Code does not apply, except for specified safety-related provisions, to mines or parts of mines used only for prospecting excavation or for extracting specified minor minerals and materials, subject to limits on depth, persons employed, and, in some cases, a prohibition on explosives. An employer must electronically notify the Inspector-cum-Facilitator within seven days when an establishment becomes a mine. The Central Government may by written order direct that all provisions of the Code apply to any such mine or part thereof subject to specified conditions.
