摘要
为研究煤矿事故致因因素中的自然因素的特征,运用文献调研、系统分析的方法分析了煤矿事故中的自然因素,认为构成矿井自然因素归为瓦斯、煤尘、自然发火、水文地质条件、顶板条件、地质构造6大类。以《中国煤矿事故暨专家点评集》中1 500余个案例为基础,以煤矿事故起数、死亡人数为主要指标,从事故发生的频次、地域和时间3个角度探讨了6类自然因素的分布特征。分析结果显示,各类自然因素从不同程度上影响煤矿事故的发生,认为自然因素对煤矿事故有较大致灾作用,并随采深增加有加重趋势。
In order to study the characteristics of natural factors in coal mine accidents, the six categories of natural factors that includes gas, coal dust, spontaneous combustion, hydrogeology, roof and geological structure are described by researching literature and system analysis. Based on over 1500 accident events in ＂ Coal Mine Accidents in China and Expert Comments Set＂ , the distribution character- istics of six types of natural factors are obtained from the aspect of frequency, regional distribution and time distribution by using the number of accidents and death toll as assessing items. Analysis shows that the natural factors have impact on coal mine accident from different extent. The natural factors are useful for coal mine accident, and the influence becomes even more serious as the mining depth is increased.
