  • 摘要: 针对直接连接断层控制点所得断煤交线的主观性与不准确性,根据"V"字形法则原理,提出了采用断层面与煤层趋势延伸面布尔求交获取断煤交线的方法。以断层控制点及断层轨迹线数据为基础,构建了断层面模型;以二次多项式模型、指数模型、Gompertz模型为基础,将剖面煤层曲线在断层处趋势延伸,构建了煤层趋势延伸面模型。通过断层面模型与煤层趋势延伸面模型布尔运算求交,得到由断层面与煤层面共同约束的断煤交线,并与直接连接断层控制点所得断煤交线进行比较。结果表明:由断层面与煤层面共同约束的断煤交线,充分顾及到煤层在断层处的趋势,更真实地反应断煤交线的空间形态,对建立煤层实体模型和指导实际生产具有重要理论与实际意义。
