Geological Disaster Prevention Countermeasures Division Of Wuan

Many types of geological disasters, the high frequency of occurrence, wide geographical distribution, the western provinces of Yunnan, Sichuan, Chongqing, Guizhou, southern Shaanxi are distributed. According to statistics, in 2012,there were 14,322 geological disasters in the country, 888 from landslides, 2088 from collapse, 922 from mudslides, 347 from ground subsidence; a total of 375 people were killed and missing, direct economic losses of 5.28 billion yuan. How to effectively prevent the occurrence of geological disasters has become a matter of national economic development and people’s lives and safety of the event, and therefore more and more attention. The party’s 18 report also made it clear that "increase the natural ecosystems and environmental protection, and strengthen disaster prevention system, improve meteorology, geology, earthquake disaster prevention capability." Wuan is located in Hebei Taihang Mountain, Surrounded by mountains, hills and downs, the overall trend of terrain is tilted from west to east.The place is a rich mineral resources, complex geological structure, more human engineering activities especially intense mining development activities in the region. it due to the number of decades of mining, so mine ecological environment has been severely damaged, buildings and roads were destroyed, land has been abandoned. Especially many area mining dregs is not standardized, resulting in a large number of mining waste piling up at random,provides a rich source of material is formed into a debris flow disaster; In addition, in the northwest of the mountain, there is also the development of geological disasters in landslides and unstable slopes, threatening the safety of the local population ’s life and property.Wuan Geohazards project to commence the study, analyzed the distribution and formation conditions for the Wuan geological disasters, disaster- environmental geological disasters, Summarizing the development features of geological disasters in Wuan city, and the formation of major geological disasters Wuan mechanism was discussed. Using prone index method in MAPGIS based on the susceptibility and prevention partition, and finally put forward the countermeasure of prevention and control of geological disasters, it provides the scientific basis and methods for the prevention and control of geological disasters in Wuan City, also provides positive reference for geological disaster prevention in Taihang Mountain area.
