DEVICE AND METHOD FOR MONITORING ROOF SEPARATION LAYER ON BASIS OF FIBER GRID IN MINING Russian patent published in 2017 - IPC E21C39/00 E21F17/18 

FIELD: mining engineering.

SUBSTANCE: device for monitoring roof separation layer on the basis of fiber grid consists of a perpendicular measuring barrel (1) installed in hole drilled in the roof, and an layout case of equipment layout (19) connected from below to the perpendicular measuring barrel (1). Mounting brackets (6) of guide roller and mounting brackets (7) of roller with steel tape are symmetrically mounted on the upper part of layout case (19), and socle beams (15) of constant strength are symmetrically mounted on the lower part. Tension springs (16) are installed on opposite ends of socle beams (15) of constant strength. The other ends of two tension springs (16) are connected to steel wire rope (3). Steel wire rope (3) passes through rollers (17) with steel tape and guide rollers (18), and extends outward from fair-lead (2) of steel wire rope at the top of perpendicular measuring barrel (1). End head of steel wire rope (3) is connected to anchor head (5). Fiber grids A (8) and fiber grid B (9) are symmetrically mounted on the left sides and right sides of the socle beams (15) of constant strength. Fiber grids A (8) and fiber grids B (9) exit outwardly from fiber fair-lead (10) through the same fiber (12) and are connected to the fiber connector (14). Also, method for monitoring roof separation layer on basis of fiber grid in mining operations using a device for monitoring roofing separation layer on basis of fiber grid in mining operations.

EFFECT: increasing safety due to higher monitoring efficiency and measurement accuracy.
