Outline
To effectively study the characteristics of potential dangers in non-coal mines in Sichuan Province and strengthen safety management, statistical analysis on potential danger data from 188 non-coal mines was conducted. The results show that the proportion of general potential dangers and major potential dangers is 91.2% and 8.8%, respectively and the largest proportion of major potential dangers is in underground mines(49.0%). The number of major hazards in on-site management is about 1.3 times that of major hazards in basic management. The major potential dangers are concentrated in five aspects of drawing management, organizational construction, slope management, electromechanical transportation, and flood drainage systems. It is recommended that mining enterprises should increase investment in safety funds, standardize data management, strengthen on-site high-risk point control, and allocate professional personnel. At the same time, it is suggested that safety supervision and management departments should focus on key points, innovate regulatory models, rely on technology and expert support, and enhance regulatory efficiency.
