摘　　要：为了表达和再现煤矿三维地质体,显示地质体内部细节,揭示地质体在煤矿井田内的空间分布规律,需研究如何构建煤矿地质体三维模型以及怎样对其进行剖切.在研究GTP三维数据模型的基础上,设计了GTP三维数据结构,构建了煤矿地质体的三维模型,并且对GTP的各种剖切情况进行了研究,设计了煤矿地质体的剖切算法、剖切求解和剖切流程,最后实现了煤矿地质体的剖切.In order to describe and reappear three-dimensional coal geological body, and display the inner detail, reveal the spatial distributional rule of geological body in the coal mine, how to realize the three-dimensional modeling of geological body and how to cut it must be studied. The GTP three-dimensional data structure was designed after studying the GTP three-dimensional data model, the three-dimensional model of geological body was realized. All kinds of GTP cutting were studied, and designed the cutting method, cutting points calculation, cutting process, in the end, the coal geological body was cut.

关 键 词：GTP 煤矿地质体 三维建模 剖切
