Guangxi Zhuang Autonomous Region Department of Land and Resources

First, strengthen team building and improve the emergency response capability of geological disasters.

Guangxi is located in the subtropical monsoon climate zone, which is hot, humid and rainy with abundant rainfall. Affected by typhoons, there are often heavy rains, heavy rains or continuous days of heavy rainfall in flood season. According to relevant statistics, most geological disasters such as landslides, collapses and mudslides that occur in Guangxi every year are related to rainfall, especially heavy rain, heavy rain or continuous heavy rainfall for many days. Every flood season is a period of frequent geological disasters in Guangxi. Under the influence of rainfall, especially heavy rainfall, sudden and mass geological disasters such as collapse, landslide and debris flow occur from time to time, causing casualties and people's lives and property losses, threatening people's lives and property safety. Once a sudden geological disaster occurs, the relevant departments of the local government must start the emergency plan for geological disasters, carry out emergency rescue and disaster relief, and carry out a series of emergency work such as geological disaster investigation and post-disaster disposal. Because of the strong professionalism in the cause analysis, occurrence and development trend, distribution characteristics and stability evaluation of geological disasters, it is necessary to have a professional team of geological disasters to assist in the investigation and technical guidance, provide technical services, and provide a basis for local governments to prevent and reduce disasters.

The Department of Land and Resources of the Autonomous Region attaches great importance to the construction of emergency teams for geological disasters, and regards Guangxi Geological Environment Monitoring Station as the main technical support unit for the prevention and protection of geological disasters in the whole region. The station was established in 198 1. After the institutional reform in 2000, it is a public welfare institution directly under the Department of Land and Resources of the Autonomous Region and fully funded by the government. Before 2008, the main station was approved by the editorial board of the autonomous region to set up six municipal substations, 1 town station. In 2008, the editorial board of the autonomous region approved the establishment of municipal geological environment monitoring stations in Wuzhou, Baise, Guigang, Laibin, Hezhou and Chongzuo. At present, except Fangchenggang and Qinzhou (Beibu Gulf Geological Environment Monitoring Station is responsible for monitoring the geological environment of Beihai, Fangchenggang and Qinzhou), all districts and cities in the region have set up geological environment monitoring stations. In order to straighten out the management relationship, 20 1 1 and the department of land and resources of the autonomous region set up geological environment monitoring stations in Fangchenggang and Qinzhou respectively. In the past three years, the finance of the autonomous region has increased the cost of geological disaster investigation and emergency equipment purchase at the main station, and purchased advanced equipment such as V8 multifunctional electrical prospecting instrument, geological radar and 3D laser scanner. In recent years, the main station has played an important role in the investigation of sudden geological disasters, the monitoring and forecasting of geological disasters, the knowledge training and technical guidance of group monitoring and prevention of geological disasters, and has investigated more than 200 sudden geological disasters every year. In case of sudden geological disasters, after receiving the information, they can rush to the scene in time to carry out emergency investigation and provide technical guidance for government departments to rescue geological disasters. 20 10 major sudden geological disasters in Yulin, Wuzhou and Laibin in the autonomous region, and the emergency work of landslide in Guangkengcao quarry, Luojiang Village, Xianshui Town, quanzhou county 20 1 1 main station has been well received by the local government and the masses for its rapid response and excellent technology.

In order to ensure timely and effective emergency response in case of sudden geological disasters; Organize on-site emergency investigation in time, prepare emergency investigation report and report it in time. When a sudden geological disaster occurs, all emergency detachments of Guangxi Geological Environment Monitoring Station act immediately in line with the purpose of serving the people and solving problems for the government, and rush to the scene of geological disaster in time together with relevant local departments to find out the geological environment conditions, causes and development trends of geological disasters, and put forward preventive measures and suggestions. Actively cooperate with and assist the local government to organize emergency rescue and disaster relief, provide technical services and consultation, evacuate people in dangerous areas in time, and avoid the recurrence of hidden dangers of geological disasters. It fully embodies the responsibility of the main station as the technical support of the department of land and resources of the autonomous region, and also reflects the rapid response ability of each emergency detachment.

Typical examples are as follows:

1.2010 "6.2" sudden geological disaster and "6. 15" sudden geological disaster emergency work.

On June 2, 2065438+ 00, under the influence of heavy rainfall on June 15, thousands of geological disasters such as collapses, landslides and mudslides occurred in Rongxian Town, Du Nan Town, Ma Lu Town and Shatou Town of Cangwu County, and the hillsides were riddled with holes and devastation (Figure 65438+). At that time, many media reported these two incidents to varying degrees, which had a great social impact.

Guangxi Geological Environment Monitoring Station dispatched immediately after receiving the news. On the way to the disaster site, it took nearly five hours to reach the geological disaster site because all the roads were blocked by mudslides on the hillside. At that time, it was near evening, and the emergency personnel of the station forgot to rest and eat, and immediately threw themselves into the investigation work, fighting all night, climbing the hillside which was still quite dangerous for inspection and conducting geological disaster investigation (Figures 3 and 4). Find out the cause, distribution range and location of geological disasters, discover some new hidden dangers in time, determine the stability of geological disasters, stabilize the mood of victims, and eliminate the victims' worries about whether the same geological disasters will occur in resettlement sites, and sleep in the farmhouse with local victims that night. Through the investigation of wharf technicians, it is determined to provide safe temporary resettlement places for local victims in time, guide the disaster relief work of finding missing persons, provide timely technical guidance for local emergency rescue and disaster relief, provide technical services for emergency rescue and disaster relief, solve problems for local governments, stabilize the mood of victims, and make emergency rescue and disaster relief and post-disaster disposal timely and orderly. The local government is very satisfied with the work of the members of the terminal emergency team and fully affirms it.

2.20 1 1 Quanzhou "5 9" geological disaster emergency work

20 1 1 May 9, 2008 13: 00 to 13: 30, a landslide occurred in Guangkengcao Mountain, Luojiang Village Committee, Xianshui Town, quanzhou county, Guangxi, causing 22 people missing (all of them were found in the later rescue and died). After the disaster, Xiao Jiangang, director of the Department of Land and Resources of the Autonomous Region, called Zhang Wenjun, deputy director, requesting to immediately lead experts to the scene to guide the disaster relief work. After receiving the geological disaster information at 14: 35, Guangxi Geological Environment Monitoring Station quickly launched the emergency plan for geological disaster investigation. Appointed by the Ministry, Director Huang Huimin led the geological experts to dispatch urgently and rushed to the site for emergency investigation on the afternoon of 16 (Figures 5 and 6). After the emergency personnel of the main station arrived at the geological disaster site, they did not rest and immediately put themselves into the investigation. They climbed the steep hillside with hidden dangers of landslides and collapses, inspected and conducted geological disaster investigation. They found out that the main causes of geological disasters are particularly developed rock fractures, steep terrain slopes and landslides caused by heavy rainfall. In addition, it is a high landslide, which has formed a strong impact force during the sliding process. The distribution range and hidden dangers of geological disasters are found out, and the stability of geological disasters is determined. Guide the search for missing persons and provide technical guidance for local emergency rescue and disaster relief in time. Emergency technicians from the main station and local emergency rescue and relief headquarters spent nine days fighting day and night at the disaster relief site to provide professional technical services for geological disasters. Due to the availability of technical services, no secondary disasters occurred in the whole rescue process (Figures 7 and 8). In particular, the investigation results of the causes of geological disasters provided a strong scientific basis for the local government to define and identify the responsibility of this incident, provided a basis for emergency rescue and resettlement work, stabilized the mood of the affected residents, solved problems for the government, and made emergency rescue and post-disaster disposal work orderly, and finally successfully ended the emergency rescue and relief work of geological disasters. The local government was very satisfied with the technical support and emergency work of the central station and gave full affirmation and evaluation.

The second is to give full play to professional advantages and make new contributions to finding water and drilling wells in Dashishan area.

1. Looking for water and drilling wells for emergency drought relief

From August to May 20, 200910, the rainfall in Guangxi was seriously less, and the objective conditions of high temperature and little rainfall, combined with the drought and water shortage of karst surface in Dashi Mountain area, led to a once-in-a-century drought, of which the drought in western Guangxi was the most serious. As of March, 20 10, there were 12 cities in Guangxi, with 7,844,500 mu of crops affected by drought, including 4,644,300 mu of light drought, 2,945,000 mu of heavy drought, 255,200 mu of dry land and 4,069,400 mu of water shortage. Due to drought, 6.5438+0.7646 million people and 870,900 large livestock have difficulty drinking water, including 6.065438+0.8 million people in Hechi City and 862,900 people in Baise City. The number of people who need water supply to solve the drinking water problem is 6.5438+0.877 million, including 6.5438+0.297 million in Hechi City and 58,000 in Baise City. The population with difficulty in drinking water is increasing by 200,000 per week. On the afternoon of March 17, Guangxi launched the second-level emergency response of the drought early warning emergency plan.

The disaster affects the hearts of workers in Guangxi land and resources system, and drought resistance is the order! On March 18, the Department of Land and Resources of the Autonomous Region urgently deployed relevant drought relief work. Eight professional teams including Guangxi Hydrogeological Engineering Geological Team, Guangxi No.4 Geological Team, Guangxi Geophysical Survey Institute, Guangxi Guilin Hydrogeological Engineering Geological Survey Institute, Guangxi Beihai Hydrogeological Engineering Mineral Geological Survey Institute, Guangxi Geological Survey Institute, Guangxi 272 Geological Team and Guangxi Geology and Mineral Construction Engineering Co., Ltd. have also sent teams to fight drought.

By May 3 1 2065438, it took more than 70 days to complete the hydrogeologic survey of 873 villages in severe drought areas and the water prospecting and geophysical exploration work of 290 villages. 234 rigs were put into operation, 255 boreholes were drilled, and the footage was 2 135 1.3m, and 65438 wells were completed. The total water inflow is 662 12.7 m3/ day, which can solve the drinking water problem of 1324254 people or 2204893 livestock (Figure 9 to Figure 15).
