Abstract: With the gradual mining of the Hemushan Iron Mine to the production reduction period,the safety production pressure brought by the mining of the mine suddenly increased.Provide theoretical guidance for the next stage of safety production in Hemushan Iron Mine.By collecting and studying the typical annual safety accidents,the number and distribution of accidents are summarized,the analysis of safety production conditions and the optimization of safety measures are analyzed.The analysis results are: ①The roof falling accident accounted for 72.97% of the total accidents of the year,which was the main safety accident of Hemushan Iron Mine in 2019(-215 m and -262.5 m stratification are 10 times).The annual accident rate of 10,000 tons is 0.36 times;③The next year (2020) the security situation is more severe,more strict safety production technology and Management measures to ensure safe mining.

Key words: production reduction period,iron mine accident,accident law,safety measures
