Design and Key Technology Research of Coal Mine Safety Comprehensive Monitoring System based on AHP Analysis Method

Abstract

With the continuous deepening of coal mining activities, the importance of coal mine safety has become increasingly prominent and has become a widely concerned focus of society. In order to improve the efficiency and accuracy of coal mine safety management, we adopted the Analytic Hierarchy Process (AHP) to design and implement a comprehensive monitoring system for coal mine safety. This system not only combines the actual situation of coal mining, but also fully utilizes modern technological means to ensure the safety and stability of coal mining operations. Firstly, we conducted an in-depth analysis and statistical analysis of the causes of 45 coal mine gas explosion accidents that have occurred in the past 5 years. Through detailed accident investigation and data analysis, we identified the key factors leading to gas explosions and constructed a dishonesty model for gas explosion accidents based on the Analytic Hierarchy Process. Based on the current situation of coal mine safety monitoring system and the development trend of wireless sensor network technology, a design scheme of coal mine comprehensive monitoring system based on wireless sensor network is proposed. Based on the CC2430/CC2431 node design, a security monitoring system in wireless sensor networks has been implemented. This system adopts advanced wireless communication technology to ensure stable data transmission and real-time processing. At the same time, we also conducted strict testing on the system to ensure its reliability and stability in practical applications. The test results in a simulated mine show that when the distance between wireless nodes is 10m, the system can meet communication requirements, achieve accurate data transmission and real-time monitoring.
