## BUILDING AND APPLICATION OF A MULTILAYER DIGITAL ELEVATION MODEL BASED ON THE BOREHOLE DATA

• 摘要: 根据某矿区的地质钻孔资料，划分了不同层面并对地层的交叉与缺失做了处理. 利用不同层面的高程值建立不同层面的等高线，再由Kriging插值法得到矿区的三维地层模型. 从所建模型中抽取剖面图并与矿区实际勘探线剖面图进行比较，验证了模型的可靠性. 最后从建立的多层DEM模型中抽取剖面数据进行有限元数值模拟，并与实际勘探和采掘过程中揭露的断层位置比较，两者结果非常吻合，为该矿区采掘设计和构造预测提供了一定的参考.

Abstract: Multilayer digital elevation model is simple andeffective in building a three-dimensional stratigraphic model. Based onthe borehole data of a coal field, different geological layers areidentified. The method for gathering and processing the data of the cross-layerand absent-layer is proposed. The elevation contours of the different layersare obtained with the processed elevation data. The Kriging interpolationmethod is used to get the data of the strata for the three-dimensionalstratigraphic model of the mining area. The profile diagrams are drawn fromthe built three-dimensional stratigraphic model and compared with that ofthe same sections by manual drawing. The results show that the former modelis more reliable than the latter. Finally, the numerical simulation withfinite element method is carried out by drawing data from the builtthree-dimensional stratigraphic model. The simulating results also show thatthey agree fairly well with the results obtained by geological survey andthose gathered in coal mining process and can be used incoal mining design and tectonic prediction.
