Abstract: In view of the existed common problem of "static compliance and dynamic landslide" in the standardization construction of coal mine safety production, taking Longquan Coal Mine in Sichuan Province as the research object, a dynamic management system for safety production standardization based on PDCA cycle is systematically constructed. Through the Plan stage, quantitative goals are clarified, full staff training and on-site demonstration are promoted through the Do stage, multi-dimensional inspection and evaluation are implemented through the Check stage, successful experience is solidified and a new cycle is initiated through the Act stage, a closed-loop management mechanism of "goal-execution-verification-optimization" is formed. Taking the 1115-2 fully mechanized mining face of the mine as an example, by optimizing the positioning accuracy of hydraulic supports and pipeline layout, the equipment failure rate is decreased by 18.8% and the maintenance efficiency is significantly improved. A dual dimensional management paradigm of "static compliance+dynamic maintenance" is studied and constructed, which means that one-time compliance and acceptance is achieved through institutionalized solidified standards, and continuously improves are conducted through PDCA cycle spiral iteration, avoiding management landslides. Ultimately, standardization requirements are integrated into daily management to achieve normalization, providing replicable practical references for the standardization construction of safety production in small and medium-sized coal mines.
