　　TType Top Plate Separation Instrument About Products

　　LBY-2/3 type roof delamination meter (vertical: measuring points 2 and 3)

　　The roof separation monitoring instrument, also known as the tray type roof separation indicator, is a specialized monitoring instrument for monitoring the movement of roof rock layers. It is mainly suitable for roadway roofs supported by anchor rods and working faces that require measurement of roof displacement. It provides scientific basis for coal mine engineering technicians and monitoring personnel to determine the length and tensile strength of anchor rods, and to understand the rationality and economy of the anchor rods used. Thus effectively preventing the occurrence of roof collapse accidents and ensuring coal mine production.

　　Top plate delamination meter, also known as multi-point displacement meter (balance type, straight rod type)

　　The roof separation instrument is a specialized monitoring device used to detect the movement of roof rock layers. It can display the delamination of the roof rock layer within the length range of the anchor rod and outside the same range of the anchor rod separately. To provide scientific basis for coal mine engineering technicians and monitoring staff to determine the length and tensile strength of anchor rods, understand the rationality and economy of the anchor rods used. Thus effectively preventing the occurrence of roof collapse accidents and ensuring coal mine production.

　　The roof separation indicator mainly consists of a base anchor head, a measuring rope, a sleeve, a waterproof plate, an inner measuring cylinder, and an outer measuring cylinder.

　　TRegulations for the Use of Type Top Plate Separation Instrument

　　Install an LBY-3 roof separation indicator every 5M-10M in the roadway; The installation position of the delamination indicator should not exceed 1.5m from the front, otherwise it cannot capture the entire process of roof delamination;

　　The steel rope should be coiled in advance and unfolded one by one when pushed into the anchor to prevent entanglement and knotting;

　　Shallow anchor points must be accurately positioned, and markings can be made on the installation rod in advance for this purpose;

　　After installation, both scale verniers should be in a freely expandable state without any jamming phenomenon;

　　The construction team should incorporate the setting, installation, and display of the roof separation indicator into the responsibility system for tunnel construction. For example, one LBY-3 roof separation indicator should be installed every 5M-10M in the roadway;

　　The tray is fixed to the surface of the tunnel by fixing anchor heads

　　In order to further grasp the dynamics of mining pressure and observe the changes in the roof, it has been decided to install roofs at various underground tunnels and tunnel intersections

　　The board separation instrument is used to regularly observe and grasp the situation of the top plate, and the "Regulations for the Management, Installation, Observation, and Use of the Top Plate Separation Instrument" are specially formulated

　　Fixed ":

　　TInstallation of Type Top Plate Separation Instrument

　　The roof separation instrument is installed by each construction team according to the actual situation of each tunnel, and each tunnel is connected

　　The top plate delamination meter is installed at all fork points, and the specific installation standards are as follows:

　　2. The installation of the top plate delamination meter shall be drilled with a hole depth of 7m. The installation of the tension line at deep points shall not be less than 7m, and at shallow points shall not be less than 2m (both tension lines shall be installed inside)

　　3. When installing, first install the deep tension wire, then install the shallow tension wire. After installing everything, fix the end of the tension wire with screws

　　4. The hole of the top plate delamination instrument is perpendicular to the top plate to ensure the natural sagging of the delamination instrument tension line
