和睦山铁矿减产期安全生产条件分析与安全技术措施优化

随着和睦山铁矿逐步开采至减产期，矿山开采带来的安全生产压力骤增。为了给和睦山铁矿下一阶段安全生产提供理论指导，通过收集、研究年度典型安全事故，总结了事故数类型和分布规律，分析了安全生产条件分析并进行了安全措施的优化，分析得出：①进路冒顶事故占全年总事故的72.97%，为2019年和睦山铁矿的主要安全事故；②三季度发生事故次数多达18次，多分布在靠近顶底柱位置（-215 m、-262.5 m分层均为10次），全年万吨事故发生率为0.36次/万t；③下一年度（2020年）安全形势更为严峻，必须采取更为严格的安全生产技术与管理措施，确保安全开采。

Analysis of Safe Production Conditions and Optimization of Safety Technical Measures in Hemushan Iron Mine

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.
