**2. Top Plate Separation Tester Installation Procedure:**
(1) Drilling the hole: Use an alloy steel drill bit with a diameter of Φ27 mm or Φ28 mm, along with a hollow hexagonal drill. Before drilling, tap the top of the rock to assess its condition, identify loose or dangerous rocks, and confirm the area is safe before proceeding. The hole must be precisely positioned, ensuring the roof naturally droops. The drilling depth should be 1 meter deeper than the anchoring depth of the nearby anchor cable.
(2) Installing the anchors: Insert the deep base anchor into the hole using the anchor cable until it reaches the designated position (same length as the anchor cable). After removing the cable, pull the wire rope to check if the anchor is securely fixed. Then install the shallow base anchor in the same manner. Finally, push the white PVC sleeve of the separator into the hole and ensure it is tightly fixed near the roof.
(3) Aligning the scales: Place the red sleeve over the two measuring points and secure the rope, cutting off any excess wire.
(4) Record initial readings: After installation, note down the initial values for both the depth and base point scales.
(5) Installation by trained personnel: All roof separation indicators must be installed by qualified technicians on-site.
(6) Management and maintenance: Each indicator should be numbered and managed systematically. The display must be neat, clear, and accurate. It should be placed in a visible location, facing the sidewalk for easy observation. The construction team must keep the device and its records clean and functional.
(7) Prevent debris interference: Ensure that the measuring tubes in both the deep and shallow sections are not blocked by mesh or other debris, which could affect the monitoring process.
(8) Observation record: The construction team must maintain an observation log for the roof separation indicators. This log should be filled out by on-duty inspectors and checked daily for at least five consecutive days. The duty team is responsible for daily monitoring, while the mine pressure group will periodically review the data and inspect the installation quality.

1. **Responsible Person**: The team technician is in charge of monitoring and recording the roof separation meter in the working tunnel, filling out the roof separation management board, and summarizing the data. Other teams must also observe the indicators regularly to detect anomalies promptly and ensure safety.
2. **Monitoring Frequency**: Newly installed separators must be observed for at least seven consecutive days. In special areas where readings change rapidly, daily monitoring is required. In safe zones, weekly inspections are sufficient.
3. **Monitoring Method**: The reading from the deep and shallow scales equals the movement amount minus the initial value. If the roof sinks within the bolt support range, the scales for the deep and shallow base points will differ. If the roof sinks within the anchor cable support range but not in the bolt support area, only the deep scale will change. If both areas sink simultaneously, both scales will show changes, with the deep scale reflecting the total sinking amount.
**Third, New Products: ACLY-2 Roof Separation Indicator, CDY-3 Roof Separation Tester, WBT-10 Roof Separation Observation Instrument**
The construction team’s technicians analyze the day's monitoring data. Any abnormalities are reported to the production geological department immediately. Data is reviewed with technical staff, and the findings are submitted to the chief geologist. Based on the analysis, corrective actions are proposed and implemented. The direct supervisor reviews the roof separation data monthly and issues rectification notices when necessary. The team must address all issues according to the standards outlined in the notice.
