Abstract
Coal seam floor, fault are important geological interfaces to be focused in the process of coal exploration and mining. This paper analyzes in detail the characteristics of complex coal seam floor and fault and proposes corresponding effective 3D reconstruction method for them respectively. For complex coal seam floor surface, this paper proposes blocking partition 3D reconstruction method in which complex coal seam floor surface is decomposed by boundary lines into modeling blocks with single internal structure. These modeling blocks are reconstructed in 3D form separately. Meanwhile, this paper puts forward a new method which adopts multi-source, multi- category geological data to collaboratively reconstruct 3D fault model in the exploration area. It makes full use of the advantages of each type of fault data and makes up disadvantages. The methods mentioned above have good effect of 3D geological modeling in Sanlutian exploration area of Muli area, Qinghai province. So these methods will have wide application prospect.
