Abstract
The author characterizes ore production loss depending on time, properties and production technology. Typification of technologies aimed at improvement of ore-drawing quality using canopies is performed. Operating principle of canopies is theoretically generalized, and recommendations on using canopies are made. It is proved that separation of abandoned ore from overlying rocks under canopies during ore-drawing improves mineral production quality.
