PROCESS OF FILLING OF WORKED-OUT SPACE WHILE DEVELOPING KIMBERLITE PIPE BY POWERED MINING COMPLEX IN RISING STRATUM AND GEAR TO CONDUCT FILLING OPERATION Russian patent published in 2001 - IPC

FIELD: mining industry. SUBSTANCE: invention can be recommended for development of pipe-like ore bodies. Process deals with provision for uninterrupted operation of mining complex. Process of filling includes compaction of dry filling by static loads in layer of worked- out turn of pipe lying beneath. With this in mind pressure close to breaking effort for mass above support is formed under base of support prior to its advance, complex is fed with dry filling and freed space is filled with dry filling in the form of inclined strips, dry filling is compacted with static load of inclined plane with its translation in inclined layer and it is simultaneously consolidated with dynamic loads through same plane. Portion of bulk of dry filling can be injected with 3-10% of cement, cement can be added where enhanced strength is required. Gear to conduct filling operation includes powered mining complex, conveyer of dry filling with cylinder of its registration and source of dynamic loading. Wall with hydraulic cylinder of static loading is suspended from frame hinged to base of powered support and fitted with additional hydraulic cylinder of turn of frame and static loading of guarding wall. The latter uses striking units. Gear can have additional mixer to prepare dry filling with addition of cement and mechanism to re-load mixture on to filling conveyer. EFFECT: provision for uninterrupted operation of powered mining complex for underground development of pipe-like ore bodies. 4 cl, 6 dwg, 2 tbl
