Digital Geological Platform Building Of Zhang Cun Mine

This paper tightly around the use of borehole data and contour of the get a village coal mine3D geological data to build coal mine platform on the subject, through the analysis of get a village coal mine drilling data, will get a village coal mine geological body can be divided into surface layer, and the earth surface of base plate, the no.3coal seam roof, coal seam no.3floor300meters and the no.3coal seam underlying strata five geological interface and then use area topographic map, the no.3coal seam in coal mine floor contour and drilling data, based on the thickness of the inverse distance weighted interpolation method respectively to extract the ground surface, the loose bed floor, roof of coal seam no.3, no.3, no.3coal seam coal floor of the five underlying strata interface point set, then the D-TIN (di Rodney triangulation) respectively to build the five interface of irregular triangle net, and then adopts\"incision suture\" algorithm using the boundary of the adjacent interface ring build geological layer on the side of the TIN, finally all triangles in triangle mesh is used to simulate get mine3D geological model. Although model established in this paper can realize cutting model, but is not easy for the other spatial analysis, so this paper adopts GTP-TEN made in ore reserves calculation (generalized tri-prism plus rectangular pyramid) of the division of geological body way to calculate geological body by projection, spatial interpolation method, could be divided into three geological prism and a collection of rectangular pyramid, by calculating the volume of these collections coal reserves are obtained.Zhang cun mine as an example, this paper is to get a get a village coal mine is established, the three-dimensional geological visualization system, realized the deposit layer model and random Angle, according to realize the arbitrary surface model of ore deposit cutting and drilling show, attribute query, coal mine coal reserves calculation and real-time updating of ore deposit model, to get a production design, and management of the village coal mine has guiding significance.
