The overall orientation of the Laboratory:'Based in Guizhou, serving southwestern China, facing the whole country.”Strategically using its advantageous location in Guizhou (located in the karst hinterland of Southwestern China), the Laboratory has carried out fundamental, strategic, and applied research in the field of karst geological environment and karst geological hazards prevention and control to meet the national and regional development strategic needs. The Laboratory has established and improved the theory and technical method system of “karst geological environment and geological hazards”, and built an innovation platform that integrates production, study, and research in order to improve the laboratory’s decision-making counseling capability in view of karst resources, environment, and hazards issues. Having made important contributions to the economic construction and social development of Guizhou and Southwestern China, the Laboratory has become a well-known and internationally influential base for scientific research, personnel training, and academic exchange.
The Laboratory has two research directions:
Direction 1: Karst Geological Environment
Aiming at the environmental problems in the southwestern China (Guizhou Province) karst area, the Laboratory has carried out basic research on weathering biogeochemical processes and soil formation rate of carbonate rocks, evolution and response of karst groundwater systems, and agricultural geological background and crop quality.The Laboratory has also provided a theoretical basis for the protection of karst geological environment and groundwater and the development of characteristic agriculture. To tackle all sorts of environmental problems occurreed during the mining operations in the karst area, the Laboratory has also been doing research on the mechanism of mine environmental pollution process, watershed environmental pollution process, environmental impact and risk assessment, comprehensive utilization of solid waste, development of environmental impact friendly materials, and research and development of prevention and control technologies.
Direction 2: Karst Geological Disasters
Relying on the analysis of geological process mechanisms, the Laboratory has carried out research on disaster mechanism, destruction mode, stability evaluation, monitoring and early warning, prevention and control of geological hazards in karst mountainous regions, mechanism of mutual feedback between human engineering activities and geological environmental conditions in karst areas, as well as stability control and disaster prevention of rock and earth mass in the construction of large-scale projects in karst areas.
The Laboratory has set up open funds to sponsor all research and development projects related to karst environment and geological disaster prevention. 'The director fund' is used for the initiation and pre-research of major science and technology projects, and is mainly open to regular researchers and visiting researchers in key laboratories. To date, the Laboratory has offered 680,000 yuan to fund 14 projects.
At present, the Laboratory has fixed assets worth of 24,195,300 yuan , of which 1.545 million yuan is for professional software and the remaining 22,653,300 yuan is for testing equipment. Since 2012, with the support of the National 211 Promotion Program and the Western University Construction Project, it has made considerable progress in view of laboratory equipment, adding 12,535,200 yuan of new equipment. In 2014, under the impetus of the construction of a large-scale instrument and equipment sharing platform at Guizhou University, all large-scale equipment belonged to the Laboratory was included in the sharing platform. As a result, users can access all large-scale equipment of the Laboratory via online reservation.
The Laboratory has cooperated with Nanjing University, Chengdu University of Technology, China University of Geosciences (Wuhan), China University of Geosciences (Beijing), Institute of Geography of the Chinese Academy of Sciences, and the provincial research institutes and enterprises in collaborative scientific research projects and base construction work. It has been successively approved to co-build the Guizhou Province Karst Mountainous Region Geological Hazard Prevention Engineering Technology Research Center, Guizhou Province Geological Engineering Graduate Innovation Practice Base, Guizhou Province Graduate Workstation, Ministry of Land and Resources Chongqing Nantong Mine Geological Environment Field Observation Station, and field research bases of Fuyang Shuanghe Caves, Zhijin Cave, Zhengye Group, No. 114 team of Provincial Bureau of Geology and Minerals, and No. 104 team of Bureau of Nonferrous Metals.
