'mining-related' originates from Modern English as a compound of two elements: 'mining' (the gerund of the verb 'mine') and 'related' (the past participle of 'relate'). 'mining' is formed from 'mine' + '-ing', and 'related' ultimately derives from Latin via Old French.

'mining' developed from the verb 'mine' used in Middle English (formed from earlier Germanic and Romance influences) and then formed the gerund 'mining'; 'related' comes from Latin 'relatus' (past participle of 'referre') via Old French 'relater' and Middle English 'relaten', giving the past participle 'related'. These elements combined in Modern English to create the compound adjective 'mining-related'.

Individually, 'mine' originally denoted a place or act of extracting minerals and 'relate' meant 'to bring back' or 'tell' in Latin-derived senses; over time the compound adopted the straightforward modern sense of 'having a connection with mining activities'.
