Embodiment 1

[0033] An indoor ore-drawing system for multi-point mining, such as Figure 1~2 As shown, it includes the mining machine 1, the lifting platform 2 of the mining machine, the up and down movement mechanism, the front and rear movement mechanism and the left and right movement mechanism;

[0034] Wherein, the described up and down moving mechanism is connected with the lifting platform 2 of the mining machine; the described up and down moving mechanism is made up of four worm gear (leading screw) elevators, and the described worm gear (leading screw) elevator consists of screw rod (leading screw) 31, Lifting nut 32 and worm gear 33 are composed, and described worm gear 33 is installed on the ground, and described screw (leading screw) 31 is inserted in the worm gear 33, and described lifting nut 32 is sleeved on described screw (leading screw) 31 On; described screw rod (leading screw) 31 rotates under the drive of worm gear machine 33, drives the lifting nut 32 on the screw rod...

Embodiment 2

[0046] An indoor ore-drawing system for realizing multi-point ore extraction, the structure is the same as that of Embodiment 1, the difference is that the up and down moving mechanism is replaced by four hydraulic lifts, and the four hydraulic lifts are powered by one hydraulic power source, and the ore extraction machine goes up and down The four corners of the platform are respectively fixedly connected with the tops of the hydraulic lifts, so as to ensure the synchronization of the lifting heights of the four hydraulic lifts.

Abstract

The purpose of the present invention is to solve the problems existing in the existing indoor ore-drawing experiment with a small shovel to shovel out ore, and propose an indoor ore-drawing system and method for multi-point ore-drawing, which belongs to the technical field of ore-drawing simulation. The indoor ore-drawing system for multi-point mining includes a mining device, a lifting platform for a mining machine, an up-and-down moving mechanism, a front-and-back movement mechanism, and a left-right movement mechanism; The mining device is connected with the forward and backward movement mechanism, the left and right movement mechanism is connected with the front and rear movement mechanism, and the up and down movement mechanism is connected with the lifting platform of the mining machine. The system builds a mining machine lifting platform, installs the mining machine on the platform, controls the lifting platform to perform three-dimensional movement through different power sources, and realizes multiple sections of the indoor ore-drawing device, multiple ore-discharging roadways or a single Multi-point mining at different positions in the mining tunnel.

Description

technical field [0001] The invention belongs to the technical field of ore-drawing simulated mines, in particular to an indoor ore-drawing system and method for multi-point ore extraction. Background technique [0002] In the indoor ore-drawing experiment of the segmented caving mining method, in order to overcome the influence of the boundary of the model box on the effect of the ore-drawing experiment, at least three segments are usually selected, each segment has three ore-out routes, and each route has three The experimental model composed of the above ore-breaking steps is used for ore-drawing experiments. After the mine is finished, according to the total amount of pre-filled ore, the total amount of ore shoveled out, and the amount of waste rock mixed in, the ore loss rate and waste rock mixing rate under different mining structure parameters are analyzed, and the impact on the ore loss rate is studied. The factor of mixing rate with waste rock finally provides a bas...
