摘要
由于技术手段的限制,勘探中获得的各种原始地质信息及经过处理的探测成果等,均存在一定的局限性或人为性。为了降低构造解释的人为性,提高构造解释的科学性,提出了数字曲面模拟技术。该技术是利用地质勘探获取的离散数据,通过曲面模拟来构建矿层底面的形态。分析了适合煤层底面曲面模拟的数学模型。通过对宁夏冯记沟南部B区四煤的研究表明,数字曲面模拟技术能够有效地分析和研究煤田构造,为煤田构造研究提供了新的途径。
Restricted by technique and means, there are some artificiality and localization in various original geological information and worked result gained from the exploration. Digital curved surface fitting is a new structural examination technique, it can construct ore basal shape by utilizing discrete data which gained from exploration, in order to improve the scientific factor in structural examination. By anglicizing mathematical model which fits surface fitting in floor of coal seam, researching No.4 coal bed of B section in south of Fengjigou, Ningxia municipality, the authors indicate that digital surface fitting can analyse and research coalfield structures effectively, and it offers a new way for studying coalfield structures.
