1950-2022年中国煤与瓦斯突出事故的时空分布规律
Spatial and temporal distribution of coal and gas outburst accidents in China from 1950 to 2022
摘要
Abstract
To clarify the occurrence patterns of coal and gas outburst accidents,statistical analysis was conducted on coal and gas outburst accidents in China from 1950 to 2022 from the spatial and temporal dimension,and preventive measures and suggestions were proposed.The research results indicate that the temporal distribution pattern of coal and gas outburst accidents in China from 1950 to 2022 can be divided into three periods:a period of significant increase(1950-1980),a period of continuous improvement(1981-2000),and a period of stable decline(2001-2022).The spatial distribution pattern is wide range,relatively concentrated,more in the south and less in the north,and serious in the south and slight in the north.The number of coal and gas outburst accidents gradually decreases over time,and the ratio of the number of deaths to the total number of deaths in coal mine accidents fluctuates and increases over time.The spatial distribution of coal and gas outburst mines is generally characterized by more in the south and less in the north.The research results provide a basis for the prevention and control of coal and gas outburst accidents in China.关键词
