Research on construction method and information system of double prevention mechanism in iron mine

Abstract

At present, there are many problems in the construction process of the double prevention mechanism in iron mine, such as unclear construction steps, disconnection of construction process, and deviation of construction priorities, et al. Based on the PDCA cycle mode and the improved risk assessment method for working conditions, the construction method of double prevention mechanism in iron mine is analyzed and studied. The yaahp meta-decision software (Analytic Hierarchy Process software) is used to determine the weight of hazardous factors and their corresponding control measures.The concept of “failure frequency” is put forward and the calculation method of accident probability (L) is modified to realize the accurate hierarchical control of accident risk; At the same time, the failure of control measures is defined as “hidden danger”, and then the transmission mechanism of hidden danger investigation and management and risk grading management and control is established.The “Information management system of double prevention mechanism in iron mine” is developed by adopting the B/S structure to realize the informatization of the double prevention mechanism construction. According to the above methods and steps, the double prevention system of iron mine can be reasonably established to effectively identify risks and control hidden dangers and provide favorable guarantee for the safe production of iron ore.
