Abstract:

Data reliability is essential for accurate identification of coal mine disaster risks. To accurately evaluate the data reliability of coal mine disaster monitoring and early warning systems, relevant policies, regulations, standards and literatures including the One Regulation and Four Detailed Rules were systematically reviewed, and a reliability evaluation method for coal mine disaster monitoring systems was proposed by integrating big data and GIS spatial analysis technology. The method was verified via field practice in disaster prevention and control at a coal mine in Shanxi Province. Results indicate that extracting the characteristics of imprecision, heterogeneity and conflict from multi-source monitoring information is the core to accurately identify unreliable data, including over-limit values, equipment failures, missing information, positional errors and abnormal frequencies. A reliability evaluation index system covering 3 primary categories (legitimacy, compliance and rationality) and 437 subcategories is constructed, which can fully restore multi-source associated information of the monitoring system throughout its full life cycle. During normal production in February 2025 at the test mine, 56 753 pieces of unreliable information were identified by this method, with a 100% accuracy rate verified by manual inspection. Furthermore, this method can dynamically assess whether existing mine monitoring systems meet disaster early warning requirements during the data preprocessing stage, and timely prompt mine maintenance and system upgrading.
