METHOD OF DEVELOPMENT OF SOLID MINERAL FIELDS USING EXCAVATING MILLING MACHINE AND SCRAPERS Russian patent published in 2015 - IPC E21C41/26 E02F3/60 

FIELD: mining.

SUBSTANCE: method of development of solid mineral fields using the excavating milling machine and scrapers comprises the use of the excavating milling machine for rock loosening with placement of milled rock mass into the dug-out trench from which it is taken by the scraper which follows the excavating milling machine continuously without stopping. The scraper scoops the rock mass to the ladle by means of the loading tray which fills the front part of the ladle with rock mass and then moves using a rake wall, and the released front part of the ladle is filled with rock mass again. Hydraulic cylinders of the tray control mechanism lift the loading tray with rock mass for final filling of the ladle front part. The ladle is unloaded through the formed slot between the ladle bottom and the loading tray lifted in guides by means of the back wall which moves to the front part of the ladle with the rake wall.

EFFECT: method improves the operational reliability and productivity when performing stripping and mining works on the fields formed by dense and hard rocks using excavating milling machines and scrapers.
