[Abstract]:Through a two-year exploration of coal resources in and around the Shitorogei coal field, the ninth geological brigade of the Xinjiang Geology and Mining Bureau has found out that the coal field is an extra large integrated coal field with a predicted reserve of 81 billion tons. The development and construction of this super large coal field can not only promote the development of local coal power and coal chemical industry, but also strongly support the fifth coal base in Xinjiang (Karamay-Hefeng), which will bring far-reaching influence to the economic and social development of the western area of Junggar Basin. In order to speed up the development and utilization of coal resources in the Shitorogei coal field, the autonomous region requires that the hydrogeological exploration work of the Shitorogei coal field be carried out in time, which provides water resources guarantee for the large-scale development of the coal field. With the rapid development of information technology, remote sensing technology and various theoretical analysis methods have been paid more and more attention by hydrogeological researchers in the exploration and evaluation of groundwater resources. Since the 1960s, more and more researchers have used aerial photographs, satellite imagery interpretation and remote sensing techniques to study regional groundwater formation, storage, movement characteristics, and changes in water quality and quantity. And combined with various mathematical analysis methods to improve the objectivity and reliability of the results. This technique can not only save unnecessary manpower and material resources, but also provide hydrogeological basis for the planning, development and rational utilization of groundwater resources. This paper will combine the characteristics of wide remote sensing field of vision, large amount of information, spatial analysis function of GIS technology and field investigation, and use remote sensing data in the area of Shitologei coal field, through identification, Extracting and synthetically analyzing the lithology, geological structure, geomorphology and so on reflected by remote sensing image information, to identify and analyze the hydrogeological characteristics of the survey area, to explore and establish a scientific and feasible prediction model, Efficient delineation of the study area of the rich water scenic area, for the hydrogeological survey of the field work direction. In this study, by comparing the advantages and disadvantages of various mathematical analysis methods, it is determined that the fuzzy analytic hierarchy process (AHP) is used to distribute the weight of groundwater storage and migration according to each factor (evaluation index). Based on the analysis of the hydrogeological data collected in the early stage of the study area and the related documents, the evaluation indexes of the groundwater potential area are established, including the lithologic distribution, topography, geomorphology, tectonic development, land use, etc. Rainfall and river networks; By using fuzzy analytic hierarchy process (FAHP) to analyze and study the above evaluation indexes, the distribution map of groundwater rich water scenic spots in the study area is obtained, and the later drilling works are verified in the four rich water scenic spots delineated in the study area. This study provides several reliable rich water scenic spots for the future investigation of water source in the study area, and also provides effective reference and guidance for the hydrogeological survey work in the areas with similar hydrogeological conditions.
