COMPLEX FOR EXTRACTION OF ORE FROM SUPPORT TRENCH BLOCKS Russian patent published in 2005 - IPC

FIELD: mining industry.

SUBSTANCE: complex has mechanized support, combine with conveyer working tool, mounted on its boom, pump station, cable placing device and electric equipment. Support has supporting ceiling, mounted via hydraulic posts, protective ceiling, connected to base via hydraulic posts, hydraulic displacement jacks and extending top of supporting ceiling. Complex is provided with elastic shield, and mechanized support - by second base. Base and protective ceiling form a protective portion of mechanized support, and second base with supporting ceiling - its supporting portion. Base and second base are interconnected by displacement hydraulic jacks with possible forming of technological space for extraction of ore from supporting blocks of trench. Elastic shield above technological space is supported by extending top of supporting ceiling, protective ceiling is mounted under sharp angle to base for smooth setting of elastic shield. At the end of combine boom a carriage is moveably mounted, whereon second conveyer working tool is mounted. Both conveyer working tools are mounted at opposite ends of carriage with possible extraction of ore from support blocks on both sides of trench.

EFFECT: higher safety.
