摘要
为厘清煤与瓦斯突出事故的发生规律,从时间和空间 2 个维度,对1950-2022 年中国煤与瓦斯突出事故进行统计分析并提出防突措施与建议.研究结果表明:1950-2022 年中国煤与瓦斯突出事故的时间分布特征可划分为大幅上升时期(1950-1980 年)、持续好转时期(1981-2000 年)和稳定下降时期(2001-2022 年).空间分布特征为范围广、较集中、南多北少、南重北轻.煤与瓦斯突出事故发生次数随时间逐渐减少,死亡人数与煤矿事故总死亡人数之比随时间波动上涨.煤与瓦斯突出矿井的空间分布总体呈南多北少的特点.研究结果为中国煤与瓦斯突出事故防治提供参考.
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.
