摘　　要：煤矿三维地质模型技术提高了煤矿可视化和透明化程度,加快了煤矿透明工作面和智能矿山建设在煤矿领域广泛应用。东易煤矿现阶段主要采用地质平面图和剖面图相结合的分析方法,无法直观展示地质体三维空间特征。针对这一问题,采用多源数据融合的三维地质建模技术对东易煤矿选定工作面进行三维建模分析。其结果表明:1)采用三维地质建模软件可有效刻画煤矿工作面的三维地质特征,完成了煤层、围岩、夹矸等模型建立,确定了研究区地质体三维空间形态,煤层整体呈现“西北高,东南低”单斜构造特征,煤层厚度呈现“东厚西薄”的特点;2)根据回采地质剖面信息,结合巷道测量等成果,采用三维建模手段可较好分析研究区内夹矸分布情况,其中G1、G2和G63层夹矸平均厚度>0.2 m,对后续开采可能影响最为集中;3)采用三维建模手段完成了多层夹矸的精细刻画,三维可视化表现了夹矸与煤层的三维空间形态特征,为煤矿透明工作面的建设提供数据支撑。The three-dimensional geological model technology of coal mines has improved the visualization and transparency of coal mines,accelerated the construction of transparent working faces and intelligent mines in the coal mining field.At present,Dongyi coal mine mainly adopts a combination of geological plan and profile analysis methods,which cannot intuitively display the three-dimensional spatial characteristics of geological bodies.In response to this issue,a three-dimen-sional geological modeling technique using multi-source data fusion was adopted to conduct three-dimensional modeling analysis on the selected working face of Dongyi coal mine.The results showed that:1)The use of three-dimensional geological modeling software can effectively depict the three-dimensional geological characteristics of the coal mine working face,complete the establishment of models for coal seams,surrounding rocks,and gangue,and determine the three-dimens-ional spatial form of the geological body in the study area.The coal seam as a whole presents a monoclinic structural feature of"high in the northwest and low in the southeast",and the coal seam thickness shows the characteristic of"thick in the east and thin in the west".2)Based on the geological profile information of the mining area and the results of tunnel measurement,three-dimensional modeling can be used to analyze the distribution of gangue in the study area.Among them,the average thickness of gangue in the G1,G2,and G6 layers is greater than 0.2 m,which may have the most concentrated impact on subsequent mining.3)The precise characterization of multi-layered coal seams was achieved using 3D modeling techniques,which visualized the three-dimensional spatial characteristics of coal seams and coal seams,providing data support for the construction of transparent working faces in coal mines.
