Abstract

The invention discloses a large-scale three-dimensional (3D) ore drawing simulation model. The ore drawing model comprises a box, and the box is divided into an upper part and a lower part which are connected with each other, wherein, a base is arranged at the bottom of the lower part, the lower part comprises a plurality of layers, each layer is equipped with an admission passage, an admission passage port is arranged at an end part of the admission passage, a plurality of ore wall insertion slits are arranged on side walls at two ends of the lower part, and ore wall simulation boards are inserted into the ore wall insertion slits; and the box further comprises height-joined ore wall boards with sharp angles, and the height-joined ore wall boards are arranged in the ore wall insertion slits of the upper part. The large-scale 3D ore drawing simulation model integrates all functions of a two-dimensional (2D) ore drawing model; and by adopting the model, large-scale 3D ore drawing simulation test is realized, and the similarity of ore drawing simulation effect indexes in a stope is improved.

Description

technical field [0001] The invention relates to the technical field of mining engineering, in particular to a large-scale three-dimensional analog ore drawing model. Background technique [0002] Pillarless segmental caving mining method is a mining method with high efficiency, high mechanization, simple structure, safe production and low cost, which has been gradually developed since the 1950s with the emergence of new mining technology and large-scale underground mining equipment. method. [0003] The ore-drawing research methods of the above-mentioned mining methods mainly include laboratory physical simulation experiment method, field industrial test method, and computer numerical simulation analysis method. The physical simulation experiment method is to use the physical model of ore drawing to reproduce the ore drawing prototype. Physical simulation Drawing ore drawing test is carried out with a reduced physical model similar to the field conditions. Among them, the...
