基于上覆岩层结构理论的矿山三维地质模型修正方法

Revising the mining 3D geological model based on the theory of overlying rock structure

矿山三维地质建模是目前矿山地质学和测绘学科的一个研究热点,由于原始数据的松散性和不均匀性,滞后数据也不精确,导致模型的精确度较低。依据覆岩结构理论,结合相关力学模型,通过岩石应力反算出断裂处岩石的厚度,为矿山三维地质模型的修正提供一种新的方法。经实际应用与检验,能够提高模型的精确度,更接近客观实体。

Mine 3D geological modeling is a hot research topic of mine geology and mapping disciplines because the lag data is not accurate due to the loose and uneven raw data,resulting in lower accuracy of the model.Based on the theory of overlying rock structure and combined with related mechanical model,antirock stress formula is used to calculate the thickness of the rock breaks and provide a new method for the amendment of the mining 3D geological model.Practical application and test can improve the accuracy of the model closer to an objective entity.
