Product Description

Coal Mine Gas Drainage Laser Monitoring System This is a coal mine-specific equipment based on the core technology of Tunable Diode Laser Absorption Spectroscopy (TDLAS), specially tailored for gas drainage monitoring scenarios in newly discovered and undeveloped coal mines.

Relying on high-precision laser spectroscopy detection technology, the system captures core data such as gas concentration and flow rate in real time during the drainage process. Through dynamic data analysis and accurate judgment, it scientifically defines the compliance nodes of coal mine gas drainage, providing an authoritative decision-making basis for determining whether a coal mine meets the conditions for excavation and production. Compared with traditional monitoring methods, this system effectively shortens the waiting period from post-drainage to excavation and production in new mines, drastically reducing the original six-month observation period after drainage. It significantly improves the development efficiency of new mines, and provides key technical support for coal mining enterprises to realize early capacity release and reduce project operation costs.

  • Independent research and development

  • Active monitoring

  • Maintenance-free

  • High sensitivity

  • No false positives

  • Zero false negatives

  • Strong anti-interference

    • Application Scenarios

    1. Full-Process Monitoring of Gas Drainage in Newly Discovered (Proven) Undeveloped Coal Mines: Real-time tracking of core parameters such as gas concentration and flow rate after the commissioning of the drainage system, covering the entire gas drainage process as required by the "pre-drainage before mining" principle .

    2. Compliance Determination Monitoring for New Mine Gas Drainage: Scientifically assess drainage effectiveness through dynamic data analysis, providing authoritative decision-making basis for determining mining start nodes and meeting the requirements of gas drainage compliance evaluation .

    3. Gas Control Efficiency Improvement in the Early Stage of New Mine Development: Replaces the traditional long-term observation mode, drastically shortens the waiting period from gas drainage to mining, and effectively optimizes the "extraction-excavation-mining balance" schedule .

    4. Specialized Drainage Monitoring for Newly Discovered High-Gas and Coal-Gas Outburst Mines: Adapts to precise gas management needs under complex geological conditions, supporting the implementation of the "four-in-one" comprehensive outburst prevention measures  and ensuring safe mining.

    The main function

    1. Self-developed Spectral Inversion Algorithm: It can rapidly extract gas absorption spectra from spectral signals, filter out background photoelectric noise, and features high sensitivity.

    2. Calibration-free Operation: Eliminating the need for frequent adjustments required by traditional monitoring equipment, it significantly reduces post-operation maintenance workload and operational costs.

    3. Strong Anti-interference Capability: Unlike traditional detectors that are susceptible to environmental factors and cross-gas interference, it adopts fingerprint-based detection to achieve true zero false alarms.

    4. Simplified System Structure: Facilitating easier installation and being able to meet more application requirements of customers.

    5. Ultra-long Whole-system Service Life: Greatly cutting down the equipment operation costs throughout its entire life cycle.
