HYDRAULIC MONITOR INSTALLATION WITH PIPELINE OF VARIABLE LENGTH Russian patent published in 2012 - IPC E21C25/60 

FIELD: mining.

SUBSTANCE: hydraulic monitor installation with pipeline of variable length includes hydraulic monitor with body and frame with rigidly fixed branch for water supply to body, hydraulic water supply cylinders column with rod ends interconnected hydraulically and kinematically, and oil station, the hydraulic pressure line of which is hydraulically connected to rod ends of hydraulic water supply cylinders for their extension control. The installation is equipped with trailing truck, drilling-anchoring device for drilling and anchoring down-holes that is attached at hydraulic monitor frame and drilling device for drilling down-holes at trailing truck that is kinematically connected to the frame via additionally installed two feeding hydraulic cylinders with the possibility of forward extension of hydraulic monitor in relation to trailing truck during the extension of feeding hydraulic cylinders and pulling the feeding hydraulic cylinders to hydraulic monitor with these hydraulic cylinders compression, and the rod ends of hydraulic water supply cylinders are hydraulically connected to oil station drainage at extension of feeding hydraulic cylinders, moreover, the kinematic connection of the said column with branch on frame is done by means of water supply ball joint.

EFFECT: increase of productivity and reliability of development workings process on steep pitch seams during coal hydraulic mining.
