To study the space fault network theory and the area risk of open-pit mining area, the theory and method of space fault network are applied to the study of the disaster evolution process in open-pit mining area. The open-pit mine is close to a city and has complex hydrogeological conditions. The characteristics of disasters occurring in different areas are quite different, which lead to the diversity of the disaster evolution processes. It makes disaster analysis, prevention and management more difficult. Space fault network is a theory to study the evolution process of system faults. The evolution process can be studied from the perspective of macro-evolution process and micro-event relationship. The area characteristics of the open-pit mining area are studied and the area division is carried out. Based on the existing data, the space fault networks of disaster evolution processes in different areas are established. Space fault network is transformed into space fault tree, and disaster evolution models in different areas are simplified. Three indicators, structure importance, structure complexity and structure accessibility, are proposed to measure the possibility that the edge event will lead to the target event. The characteristics and relationships of these indicators are described. Finally, taking the evolution process of south wall disaster as an example, the above three indicators are calculated, and the edge events are sorted and the significance of sort is explained. This is the beginning of the application of space fault network to the study of disaster evolution process of open-pit mine.

基于空间故障网络的露天矿区灾害演化过程研究

为了研究空间断层网络理论和露天矿区的区域风险,将空间断层网络的理论和方法用于研究露天矿区的灾害演化过程。露天矿靠近城市,水文地质条件复杂。不同地区发生的灾害的特征差异很大,这导致灾害演变过程的多样性。这使灾难分析,预防和管理更加困难。空间故障网络是研究系统故障演化过程的理论。可以从宏观演化过程和微观事件关系的角度研究演化过程。研究了露天矿区的区域特征,并进行了区域划分。根据现有数据,建立了不同地区灾害演化过程的空间断层网络。将空间故障网络转化为空间故障树,简化了不同地区的灾害演化模型。提出了三个指标,即结构重要性,结构复杂性和结构可访问性,以衡量边缘事件导致目标事件的可能性。描述了这些指标的特征和关系。最后以南墙灾害的演变过程为例,计算了以上三个指标,对边缘事件进行了分类,并说明了分类的意义。这是将空间断层网络应用于露天矿灾害演变过程研究的开端。将空间故障网络转化为空间故障树,简化了不同地区的灾害演化模型。提出了三个指标,即结构重要性,结构复杂性和结构可及性,以衡量边缘事件导致目标事件的可能性。描述了这些指标的特征和关系。最后以南墙灾害的演变过程为例,计算了以上三个指标,对边缘事件进行了分类,并说明了分类的意义。这是将空间断层网络应用于露天矿灾害演变过程研究的开端。将空间故障网络转化为空间故障树,简化了不同地区的灾害演化模型。提出了三个指标,即结构重要性,结构复杂性和结构可及性,以衡量边缘事件导致目标事件的可能性。描述了这些指标的特征和关系。最后以南墙灾害的演变过程为例,计算了以上三个指标,对边缘事件进行了分类,并说明了分类的意义。这是将空间断层网络应用于露天矿灾害演变过程研究的开端。提出了结构复杂性和结构可访问性的方法,以测量边缘事件将导致目标事件的可能性。描述了这些指标的特征和关系。最后以南墙灾害的演变过程为例,计算了以上三个指标,对边缘事件进行了分类,并说明了分类的意义。这是将空间断层网络应用于露天矿灾害演变过程研究的开端。提出了结构复杂性和结构可访问性的方法,以测量边缘事件将导致目标事件的可能性。描述了这些指标的特征和关系。最后以南墙灾害的演变过程为例,计算了以上三个指标,对边缘事件进行了分类,并说明了分类的意义。这是将空间断层网络应用于露天矿灾害演变过程研究的开端。计算上述三个指标,对边缘事件进行排序,并说明排序的意义。这是将空间断层网络应用于露天矿灾害演变过程研究的开端。计算上述三个指标,对边缘事件进行排序,并说明排序的意义。这是将空间断层网络应用于露天矿灾害演变过程研究的开端。
