Design And Implementation Of Drilling Well In In-situ Leaching Mine Design System Based On WebGL

The drilling well in in-situ leaching mine design is important part of the in-situ leaching mine minning process,in order to reduce the drilling well in the in-situ leaching mine design work for the in-situ leaching mining personnel,and improve the drilling well in the in-situ leaching mine quality,the drilling well in in-situ leaching mine design system was designed in this article.This article analyzed the main development techniques of this system,and studied this system's requirement analysis.Determined the BeeGo framework to build the system,used Go language as the back-end development language,used MongoDB database to store data,adopted WebGL,HTML5,JavaScript and so on to achieve interface display,two-dimensional graphics rendering and 3D model construction.The system was mainly divided into drilling well layout module,drilling well design module,drilling well three-dimensional display module,data management and query statistics module.In order to realize the automatic drilling well layout,this article firstly constructed the ore body boundary and calculated the initial coordinates of the plan drilling well,then deeply analyzed the three-dimensional coordinate rotation transformation algorithm,and determined to use the quaternion method to rotate the initial coordinates to obtain the actual coordinates of the plan drilling well.Next,deeply analyzed the three-dimensional space ray-triangle intersection algorithm,and determined to the use of fast space ray-triangle intersection algorithm to calculate the intersection of the surface model and the plan drilling well,the intersection of the ore body model and plan drilling well,thereby obtained the orifice coordinates and the hole bottom coordinates of the plan drilling well,finally realized the drilling well layout on the ore body model.In order to construct the drilling well design plane,this article used the point-to-arbit projection method in 3D space to construct the XZ coordinate plane in the right-hand coordinate system for exploration line design,and then constructed the plane perpendicular to the XZ coordinate plane in the right-hand coordinate system and contained an exploration line for drilling well design.In order to implement the drilling well design,this article described the drilling well drawing information by defining the center line change point and the drilling well change point,analyzed the combination of the drilling well information and the sample information to calculate the coordinates of the center line change point,then combined the drilling well information and the coordinates of the center line change points to calculate the coordinates of the drilling well change points to realize the drilling drawing.This system basically implemented all the function,it was on trial in mine production,had been recognized by users and meeted the users' need.This system is friendly,stable and reliable,assists in-situ leaching mining personnel to design drilling well and improves work efficiency for the in-situ leaching mining personnel.
