【摘要】：新疆地矿局第九地质大队通过在和什托洛盖煤田一带展开的为期两年的煤炭资源勘查,查明该煤田为预测储量达810亿吨级的特大型整装煤田。该特大型煤田的开发建设不仅可带动当地煤电、煤化工产业发展,还将强力支撑新疆第五大煤炭基地(克拉玛依-和丰),对准噶尔盆地西部地区经济社会发展带来深远影响。为了加快和什托洛盖煤田煤炭资源的开发利用,自治区要求及时开展和什托洛盖煤田水文地质勘查工作,为煤田规模化开发提供了水资源保障。随着信息技术的飞速发展,遥感技术以及各种理论分析方法在地下水资源勘查评价中日益受到水文地质研究工作人员的重视。六十年代以来,越来越多的研究人员利用航空相片、卫星图像的解译和遥感手段,研究区域地下水形成、贮存、运动特征,以及水质、水量的变化规律,并结合各种数学分析方法以提高成果的客观性及可靠性。该技术不仅可节省部分野外勘查中耗费的不必要的人力、物力,也可以为地下水资源的规划、开发和合理利用提供水文地质依据。本文将结合遥感视野宽阔、信息量大的特点、GIS技术的空间分析功能及野外实地调查,利用和什托洛盖煤田一带遥感数据,通过识别、提取及综合分析遥感图像信息反映的岩性、地质构造、地貌等,来识别、分析调查区的水文地质特征,探索建立一种科学可行的预测模型,更加快捷、高效地圈定研究区的富水远景区,为该区的水文地质调查野外工作指明方向。本研究中通过对多种数学分析方法优缺点的对比,最终确定选用模糊层次分析法根据各因素(评价指标)对地下水贮存与运移的的影响程度进行权重分配;经过对研究区前期收集的水文地质资料以及相关文献的分析研究,确立了本次地下水富水潜力区评估指标,包括该地区的岩性分布、地形、地貌、构造发育情况、土地利用、降雨量以及河网水系;通过利用模糊层次分析法对上述评价指标进行分析研究最终得到了研究区地下水富水远景区分布图,在研究区内圈定的四个富水远景区得到了后期钻探工程的验证。本次研究为研究区以后的水源地勘察提供了几个较可靠的富水远景区,同时也为相似水文地质条件地区的水文地质勘察工作提供有效的参考与指导。
[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.
