2. The former Enforcement Decree of the Coal Industry Act (amended by Presidential Decree No. 16380, Jun. 8, 1999; hereinafter “former Enforcement Decree of the Coal Industry Act”) does not limit the period of accident in cases where the disability grade is not determined as of the closing date of the mine. Thus, even if an occupational accident as of the closing date did not occur, it is subject to accident compensation benefits.
