Introduction to Mine Fire Bundle Monitoring System

The mining fire monitoring system is specialized in predicting and preventing various types of coal mine fires. 24-hour continuous monitoring of gas contents such as CO, CH4, C2H4, C2H6, C2H2, CO2, O2, N2, etc. at any location underground, to determine the degree of spontaneous combustion based on the trend of gas changes, providing scientific basis for comprehensive prevention and control of coal mine spontaneous combustion fires to ensure safe production. The system sets up a monitoring and analysis center on the ground, and uses microcomputer control to pump the gas from the underground working face, sealed area, and goaf through a bundle tube to the ground monitoring room for monitoring and analysis. Can guide the air distribution, gas drainage, pressure regulation, grouting and other work in goaf; By laying bundle tubes, it is also convenient to analyze the concentration of gas components such as gas in blind alleys that are inaccessible to workers or pose a high risk.

Composition of Mine Fire Bundle Monitoring System

The mine fire monitoring system mainly consists of dust filters, single tubes, bundle tubes, branch boxes, suction pumps, gas sampling control cabinets, monitoring microcomputers, bundle tube dedicated chromatographs, printing output equipment, system software, etc. The system is controlled by a microcomputer, and the underground gas is sent into the chromatograph by a ground pump. After the chromatograph detects the results, the computer analyzes them. The entire process is carried out under microcomputer control, with a high degree of automation. It can achieve 24-hour continuous online detection and analysis, and all analysis data can be retained. In order for the staff to reuse the data.

Characteristics of Mine Fire Bundle Tube Monitoring System

1. Bundle tube negative pressure sampling and chromatographic analysis, without the need for any electrochemical sensors;

2. The self ignition fire prevention function timely and accurately predicts the degree of self ignition through trend analysis of detection data.

3. The system automatically controls 24-hour online monitoring to achieve unmanned operation;

4. Complete output functions: generate 11 types of charts including normal analysis, beam tube analysis, trend analysis reports, and trend charts;

5. Equipped with automatic alarm function for gas content exceeding the limit;

6. There is no limit to the number of database records, and historical data can be analyzed and compared;
