事故树原理在分析煤层注水影响因素中的应用

Application of fault tree analysis in the analysis of effect factors of coal seam infusion

根据事故树的基本理论,建立煤层注水事故树模型,反映出影响煤层注水效果相关因素和各因素逻辑关系。按基本事件的性质将其划分为4种类型进行分析,讨论它们对煤层注水效果(顶上事件)的影响,并提出应从研究注水煤层自身性质;探求有效且应用性强的水处理方法;建立工作面条件和施工参数对应量化关系体系;探索有针对性的钻孔、封孔施工技术和选择、设计符合现场条件的施工设备等方面统筹考虑各因素的影响,提高煤层注水效果。

According to fault tree principle,the paper expanded the definition of fault tree.Based on generated fault tree,the article established the fault tree of coal seam infusion,analyzed the effect factors of coal seam infusion.The main factors are seam properties,water treatment method,workface condition,drilling and sealing technology,effective construction equipment,and so on.
