阳泉矿区地质灾害易发区域划分

Geological Disaster Prone Area Division in Yangquan Mining Area

通过长时间实地调查并收集资料得出阳泉矿区地质灾害的分布规律及各地质灾害的具体数据,并总结阳泉地质灾害的诱发因素。在地质灾害发生的背景成因等基础资料的分析上,将单独矿区作为评价单元,以地质灾害灾害的种类、数量、稳定性、危害特征、降雨及人类工程活动为评价指标体系,并建立评价指标的分级划分标准,最后运用GIS模糊综合评判技术进行信息量分析,评估阳泉矿区地质灾害发育度。通过计算地质灾害发育程度高的矿区有6个,低区有7个,大多数矿区的地质灾害发育度中等。

Due to the unreasonable and unplanned exploitation of coal resources,mining areas inevitably will cause different degrees of geological disasters.In this paper,the distribution of geological hazards in Yangquan mining area and the specific data of each Geological hazard are obtained through long time field investigation and data collection.The inducing factors of geological hazards in Yangquan are summarized.In the analysis of the basic data,such as the background and causes of geological disasters,we think,the individual mining areas are used as evaluation units.The types,including numbers,stability,hazard characteristics,rainfall,and human engineering activities of geological disasters,are used as evaluation indicators.The classification criteria of the evaluation index are established.Finally,GIS fuzzy comprehensive evaluation theory is used to analyze the amount of information and calculate the degree of geological disaster development in Yangquan mining area.We are calculating the high degree of geological disaster development of 6 mining areas,7 low areas,most of the mine Geological disaster development of medium.
