The reflective color display of the parallel roof separation instrument truly understands the needs of underground workers! In the pitch-black tunnels, the red, yellow, and green reflective scales are strikingly vivid—no need for strong lighting to clearly see the values at a glance. Green indicates safety, yellow serves as a caution, and red directly signals a warning, almost like installing a "traffic light" for the roof. Upon closer inspection, the scales on the tray require careful attention: whether the pointer has moved or the value has exceeded the warning line must be recorded.

Main Performance Parameters:

(1)Measurement Method: Reflective Color Display

(2) Number of Measurement Points: 2 (or 3)

(3) Range: 200 mm

(4) Reading Accuracy: 1 mm

(5) Installation Anchor Hole Diameter: 28.42 mm

Based on the analysis of data observed from the roof separation instrument, various geological conditions and lithological changes can be identified. This helps summarize the extent of separation within the anchored mesh range in supported roadways and enables timely implementation of other effective support measures. The roof separation indicator primarily consists of a base point anchor, measuring rope, sleeve, dial, inner measuring cylinder, and outer measuring cylinder.

Installation Standards and Management Requirements

Location Selection: Install one unit every 50m in coal roadways and every 100m in rock roadways. In special areas such as fault zones, spacing should be reduced to 5-20m.

Data Recording: Record initial readings immediately after installation, noting the serial number, location, and date. Establish an observation log.

Maintenance Requirements: Ensure the measuring cylinder is not obstructed by mesh. Initial error must be controlled within 5mm. Manual adjustment of readings is strictly prohibited.

Don’t find it troublesome—check daily and record weekly. Data trends can predict the roof’s "minor moods" in advance. This seemingly simple observation adds a crucial layer of safety underground. No complex operations are needed; just keep an eye on the trend of the three values.
