Project Background
Industry Pain Points and Safety Challenges
Underground coal mining features complex and enclosed operating environments with limited ventilation conditions. Multiple toxic, harmful, flammable and explosive gases including methane, carbon monoxide, hydrogen sulfide and sulfur dioxide are continuously generated during mining, tunneling and transportation processes. The accumulation and over-limit concentration of underground gases are the main causes of mine explosions, poisoning and suffocation accidents, which remain the core difficulties in mine safety management.

Project Construction Requirements
To comply with national coal mine safety production regulations, eliminate potential risks such as gas explosions and personnel poisoning, and realize visualized, digital and intelligent management of underground environmental parameters, coal mining enterprises urgently need a full-coverage underground gas monitoring system with high precision and high stability. The system must adapt to harsh underground working conditions, achieve all-weather accurate detection of gas concentrations, support real-time data upload and automatic over-limit alarm, and build a closed-loop safety monitoring system with complete software and hardware support.
Solution Introduction
Overall Solution Architecture
Targeting complex underground mining scenarios, Henan DUTESI Electronic Technology has developed a customized integrated intelligent underground gas monitoring solution. Based on self-developed high-precision gas sensors, precision detection instruments and intelligent monitoring controllers, combined with cloud data transmission technology, the solution builds a full-chain monitoring system of “front-end collection, mid-end transmission and back-end management”. It covers all high-risk underground areas and realizes uninterrupted 24-hour monitoring of underground gas concentrations and environmental parameters.
Core Applied Products
The project adopts full sets of self-developed and self-produced DUTESI core equipment, including electrochemical, infrared and laser gas sensors, special underground gas detectors and intelligent monitoring controllers. The products can accurately detect common underground hazardous gases such as methane, carbon monoxide, hydrogen sulfide, nitrogen dioxide, sulfur dioxide and acetaldehyde. All products have obtained ATEX explosion-proof certification, CE safety certification and ISO9001 quality management system certification. Fully adapted to underground explosion-proof, dust-proof and moisture-proof working requirements, the equipment delivers superior stability and safety compared with ordinary industrial products.
Core Functional Advantages
Project Implementation
On-site Deployment Plan
According to the underground roadway layout, operating area distribution and high-risk point distribution of the coal mine, the project adopts a hybrid deployment mode of “fixed installation + intensive layout”. Monitoring devices are densely arranged in core operating areas such as mining and tunneling working faces, and fixed monitoring terminals are installed at roadway entrances, ventilation nodes and surrounding goafs. Equipped with professional transmission lines to ensure stable signal transmission, the solution realizes three-dimensional full-coverage underground monitoring.
