[Abstract]:With the application of digital mine technology, the level of mining design has been raised to a new level, and the parametric design of optimal boundary has been realized in the design of open-pit mines. The mining design of underground mines is still based on experience in two-dimensional plane. Based on the 3D digital ore deposit model, this paper presents the algorithm principle and operation steps of mining unit design for Changan gold mine, and develops the computer program for dividing the middle section and ore block according to the condition of complex and variable ore body in Changan Gold Mine. With the help of 3D mining engineering software, the program can realize the automation and visualization of the subdivision of the middle segment of the underground ore deposit model and the partition of the ore block. The core of this paper is to design the algorithm for dividing complex ore bodies in vertical and horizontal space. The orebodies are divided into two steps: the middle section and the ore block. The algorithm principle of the middle division is the sequential combination balance algorithm of the minimum computing unit and the ore quantity balance principle. That is to say, the orebody is divided into minimum calculation units according to a certain height, and then the minimum calculation units are combined sequentially according to the principle of ore volume balance. Spatial segment unit partition algorithm and minimum length principle. That is to say, for a certain middle section, the division of the continuous region of the middle section is carried out first, then the space section of the orebody of a continuous region is divided, and finally the division of the ore block is completed. According to the actual geological data of Changan gold mine, the underground mining unit is divided into six middle sections by using the developed program, and the elevation, height and ore quantity of each middle section are output respectively. The results of metal content in the middle segment and the amount of ore contained in each minimum calculation unit are used to divide the ore blocks into 16 ore blocks according to the 1470 middle section of the middle segment, which is divided into 16 ore blocks. The results of strike azimuth, strike length, dip range, average dip angle, average thickness and average grade of each ore block are outputted respectively.
