Abstract

A roof abscission layer monitoring device comprises an anchoring device (1), a steel wire winding-up and paying-off device (2), a recording device (3) and a steel wire (4). When the roof abscission layer monitoring device is in a working state, the steel wire (4) is led out from the steel wire winding-up and paying-off device (2), and penetrates the recording device (3) and is fixedly connected with the anchoring device (1), and the anchoring device (1) comprises an inner ring (11), an outer ring (12), a water-swelling material (13), a connecting rod (14), a top cover (15) and a bottom cover (16). The roof abscission layer monitoring device is suitable for monitoring a roof abscission layer during ground punching, thereby being more convenient and safer to operate and wider in monitoring range.

Description

technical field [0001] The invention relates to a roof separation layer monitoring device and method. Background technique [0002] In coal mine production, the change of roof movement directly affects the safety of coal mine production. Therefore, monitoring the roof movement is a necessary means to ensure the safety of coal mine production. Among them, one of the most important means is to monitor the roof delamination status. At present, there are mainly two types of roof delamination monitoring equipment widely used: (1) digital display roof delamination instrument; (2) online monitoring test roof delamination instrument. [0003] These two roof abscission monitors drill holes to a certain depth in the mining roadway in front of the working face to the roof, and then install the anchoring device in it, so they will affect the production on site to a certain extent, and can only monitor the work The situation of the roof separation in front of the face cannot be grasped...
