受传统经验式安全管理的影响,煤矿安全管理者忽视了从隐患数据中挖掘其时空分布特征这一科学管理方法。分析了煤矿安全隐患的不同类型,基于对应分析方法研究不同类型安全隐患的时空分布规律。实证研究结果表明:四季度常见隐患主要为爆破类、顶板类和运输类,三季度常见隐患为机电类和其它类型,二季度常见隐患为水害和火灾,一季度主要发生瓦斯类隐患,但关联性不强;采煤工作面常见隐患主要为机电、火灾和其它类,掘进巷道常见隐患为顶板、爆破和水害,运输类隐患主要分布在盘区巷道和其它区域,而瓦斯类隐患分布特征不明显。
Affected by the traditional empirical safety management, coal mine safety managers ignore the scientific management method of mining the temporal and spatial distribution characteristics from hidden data. The different types of coal mine safety hazards are analyzed. Based on the corresponding analysis methods, the spatial and temporal distribution of different types of safety hazards is studied. The empirical results show that the common hidden troubles in the fourth quarter are mainly blasting, roofing and transportation. The common hidden troubles in the third quarter are electromechanical and other types. The common pitfalls in the second quarter are water hazards and fires. In the first quarter, gas hazards are mainly occurred but the correlations The hidden dangers of coal mining face are mainly mechanical, electrical, fire and other types. The common hidden danger of driving roadway is roof, blasting and water damage. The hidden danger of transportation is mainly distributed in the roadway and other areas, while the hidden features of gas hazard are not obvious.
