KJ751 Coal mine methane drainage (mining) pipe network monitoring system

KJ751 Coal mine methane drainage (mining) pipe network monitoring system

Product introduction

Based on our self-developed network equipment of sensing equipment, control equipment, substation equipment, data exchanging and interface, as well as equipment of the 3rd party sensing & control and ground host device from external purchase or being available for users, this system has realized real-time monitoring of parameters such as concentration, flow, temperature, pressure of methane and CO sampled from the measuring points in the methane drainage pipe network, such as drainage filed, branch pipe, main pipe and pump station, assorted with various kinds of sensor developed by our own, abnormal measuring point, pipeline section with leakage or block, dangerous areas can be totally detected timely, then the optimal reference and suggestion on suitable disposal solution aiming at the abnormal situations will be raised to provide evidence for methane drainage effect evaluation.

The system adopts system diagram, topological graph and electronic drawing to implement real-time monitoring and inspection, which could effectively manage the hierarchy relationship of the equipment, physical connection relationship and incident relationship between location and business. Monitoring and inspection of methane drainage pipe network and online business analyzing can be carried on intuitively and professional.

The 3rd party software data service interface provided by the system can completely integrate seamless data and business with the 3rd party monitoring and inspection system, the superior monitoring and inspection, and automatic management platform.



Performance characteristics

The system achieves online monitoring of parameters such as concentration, flow, temperature, pressure of methane and CO in the underground methane drainage pipeline, and timely analysis of possible leakage or collapse in pipe network according to monitoring parameters to provide evidence for methane drainage effect evaluation.

Point monitoring can timely detect the abnormal phenomenon of leakage and collapse. Pipe segment monitoring can timely detect the dangerous pipe section in the explosion environment. Working face monitoring provides reference for methane drainage standard analysis

High measuring accuracy of methane concentration and flow, strong anti-pollution ability, no easy to drift and obtaining of innovation patent.

A variety of sensors can be selected and configured according to the user’s environment and needs, in line with the national and industrial standards.

With stable performances, all underground assemblies adopt the reliable design of water-proof, dust-free and high shock-proof.

Combination and decomposition is very convenient.

This system is equipped with a wealth of automatic control function, also can independently carry on discrimination and power-off control with automatic alarm function.

This system is equipped with functions of self-diagnosis as well as monitoring of system operation and fault status. It can also realize dual-server hot backup ensuring the safety of monitoring data.

Technical parameters

By definition of methane drainage measuring point parameters and the related properties, multi parameter monitoring curve, different parameters curve of the same measuring point and the related parameters curve of the related measuring point realize the analysis and diagnosis of abnormal measuring point and dangerous pipe segment.

The provided flow analysis tool based on the correlation of the measuring point offers corresponding reference for drainage standard evaluation. The provided the correlation analysis of drainage abnormal offers reference for the optimization of the drainage resource.

The provided definition of drainage measuring point on parameter monitoring and switch volume monitoring based on 4 parameters supports association mapping of measuring point such as liner, convergence and branch. The system fully supports the business requirement of No.163 File.

A variety of ways to visualize the point of deployment and real-time monitoring, intuitive reflect the monitoring system of the equipment level relationship, physical connection relationship, location relationship, business relationship, equipment operation status, real-time monitoring parameters.

Complete text, systematic diagram, topology map, electrical drawing and curve monitoring business association and business analysis association of equipment anomaly and alarm

Support curve associated anomaly remind business integration, support multi-axis real-time curve monitoring and historical curve analysis, providing of a wealth of business statements based on parameters, measuring points, hourly accumulation, daily accumulation and monthly accumulation of coal mine.
