1. Tangshan Dafanghuizhong Instrument | The "Transparent Mining Pipeline Monitoring System" has been launched, bidding farewell to the era of "blind pipe"

Tangshan Dafanghui Instrument proposed a solution for the underground water supply management problem in a coal mine in Shanxi Province, which is a transparent pipeline monitoring system for the mine. The solution uses digital technology to achieve full chain control of the water supply pipeline. The specific measures are as follows:

1. Digital twin construction of "underground pipeline 3D visualization model" function implementation: restore the underground water supply pipeline network in a 1:1 ratio, and visually display the pipeline layout, equipment position, and operating status through a visualization platform, transforming blind pipes that are accustomed to being "invisible" into transparent and traceable digital models.

. Effect: Management personnel can have global control over the dynamics of the pipeline network, quickly identify waste nodes and fault risk areas, and provide intuitive basis for decision-making. Figure: 3D Visualization Model Interface

2. Construction of Underground Monitoring Network for Mining Flowmeters Equipment Selection: Mining Explosion proof and Intrinsic Safety Electromagnetic Flowmeters: Suitable for high humidity and strong corrosive environments, accurately measuring water flow velocity and total amount. Mining explosion-proof and intrinsic safety digital ultrasonic flowmeter: non-contact measurement, reduces pipeline pressure loss, and adapts to complex pipe diameters. Mining intrinsically safe substation: integrates data acquisition and transmission functions, supports multi-sensor collaborative work.

Mining intrinsic safety temperature and pressure sensor: Real time monitoring of pipeline temperature and pressure changes, liquid nucleation, and warning of abnormal working conditions. Mining sealing and intrinsic safety DC stabilized power supply: provides stable power for equipment to ensure long-term reliable operation. Technical advantages: All equipment is independently developed and has explosion-proof, dustproof, and anti-interference capabilities, suitable for high temperature, high humidity, and strong vibration environments underground.

III. Implementation of intelligent leakage diagnosis instead of manual inspection function: Real time monitoring: Continuous collection of flow, pressure, temperature and other data through sensor network, dynamic analysis of pipe network operation status. Fault prediction: Using algorithm models to identify leakage points, abnormal serial equipment, and instrument faults, and issue early warnings. Quick positioning: Combining 3D models with data correlation analysis to accurately locate the fault location and shorten the repair time. Effect: Reduce the frequency of manual inspections, lower labor intensity and safety risks. Reducing water waste rate, according to case data, can save tens of thousands of tons of water annually. Extend the service life of the pipeline network and reduce maintenance costs by about 30%.

Fourth, the overall value of the system solves industry pain points: eliminating water resource waste: achieving transparent management of water use through precise measurement and leakage diagnosis.

. Enhance emergency response capability: The time for loca
