Exploitation of the Polymetallic Antonio Ore Body, From Băița Plai Mine

Abstract The Antonio polymetallic ore body is part of the Baița Plai ore deposit. Below the XVIII horizon, it has a medium slope, a height of approx. 81 m, an average extension of 200 m and a thickness varying from 4 to 36 m. Above this horizon, the orebody was mined in horizontal slices with integral backfill and the first 9 m high sublevel with rooms and pillars. In depth, below this sublevel, 6 more sublevels with a height of 12 m are mined with sublevel caving mining method. The design of the opening, preparation and exploitation of the deposit was carried out for a production capacity of 100 k tonne/year.
