(CO) Mobile Passive Laser Detection System

1. Pre-excavation Detection for Tunnel Engineering
Suitable for the pre-construction phase of various tunnels such as highway, railway and water conservancy tunnels. It accurately detects carbon monoxide gas in the rock formations ahead of the tunnel face, avoiding explosion and poisoning risks caused by sudden gas leakage during excavation, and ensuring the safe progress of tunnel construction.

2. Pre-mining Detection for Underground Coal Seam Mining
Targeted at the gas inspection needs prior to mining in coal mine working faces and excavation faces. It detects hidden carbon monoxide-enriched areas in coal seams and surrounding rocks, provides data support for formulating mining plans, and prevents gas overflow from endangering the safety of operators during coal mining.

3. Emergency Detection for Underground Engineering
If abnormal gas warnings occur during tunnel or mine construction, the system can be quickly moved to suspected areas for supplementary detection. It accurately locates the source and concentration distribution of hazardous gases, providing real-time data support for emergency responses such as gas extraction and personnel evacuation.

4. Pre-recovery Detection for Old/abandoned Mine Roadways
Conducts environmental safety assessments before the re-mining of old mines and abandoned roadways. It detects accumulated hazardous gases such as carbon monoxide in rock and coal seams in long-term enclosed environments, identifies potential safety hazards during re-mining, and ensures the safe implementation of re-mining operations.

5. Pre-construction Detection for Underground Space Development Projects
Applicable to the pre-construction phase of underground space projects such as urban underground utility tunnels and underground complexes. It detects carbon monoxide gas in surrounding rock formations and original geological structures, avoiding gas leakage caused by construction disturbances and ensuring the safety of underground project construction.
