Description

A kind of indoor ore drawing System and method for of multiple spot ore removal
Technical field
The invention belongs to simulate mine ore drawing technical field, the more particularly to indoor ore drawing system of a kind of multiple spot ore removal and side Method.
Background technology
In sublevel caving room in ore drawing experiment, to overcome influence of the model casing boundary to ore drawing experiment effect, lead to It can often select and be at least made of there are three the above ore caving interval three ore removal routes, every route three segmentations, often segmentation Experimental model carries out ore drawing experiment.After ore removal, according to the ore total amount loaded in advance, shoveled out ore total amount and it is mixed into Barren rock amount therein, to analyze the loss late of ore and barren rock incorporation rate under different ro om -character parameters, research influences ore damage The factor of mistake rate and barren rock incorporation rate, it is final to provide foundation for stope structure parameter optimization.
In traditional indoor ore drawing experiment, ore removal mainly relies on manual type, using various forms of scuppits from simulation Discharging tunnel in, constantly shovel out and be filled in the ore in sublevel caving model casing to realize in advance, it is such go out There is following aspect in mine mode:
(1) shoveling depth can not be held well, this can have an impact the flow behavior of ore in model casing and barren rock, And then influence the loss late of ore and the incorporation rate of barren rock;
(2) ore in model casing is all shoveled out by what an artificial shovel, one shoveled, heavy workload, and experimental period is long;
(3) ore removal change in location is big, especially when ore removal position height smaller (ore removal segmentation reduces), testing crew frequency It is numerous to bend over, it is easy that it is made to generate fatigue.If model casing is placed in higher position, the ore removal of upper segment is because going out mine mouth position It sets higher, and causes inconvenience.
