[0009] 2) Mixed loading: The concentrator plans the proportion of ore to be mined according to the situation of the stope and the mining personnel, and assigns a special person every day to distinguish the ore to be mined according to the geological data and the actual ore color appearance of the stope; It is difficult to actually track the ore blending process
Whether the mining plan is strictly implemented in the mining process is related to the condition of the equipment, the sense of responsibility of the personnel, and the geological changes; due to the ineffective connection of shovel loading, truck transportation and iron transportation, the concentrator cannot judge whether the proportion of ore mix meets the requirements , especially whether the proportion of refractory minerals is normal, which seriously restricts the normal production of the dressing plant;

Embodiment Construction

[0040] An embodiment of the present invention will be further described below in conjunction with the accompanying drawings.

[0041] like figure 1 and figure 2 As shown, the mining intelligent ore dynamic ore blending optimization method in the embodiment of the present invention includes splitting, splitting, mining, weighing, and adopting the method of establishing a dynamic planning ore blending model to obtain the optimal ore blending plan that meets the target ore ratio, Ore drawing, transportation and ore blending grade forecast, the overall detailed flow chart of the method is as follows image 3As shown, the details are as follows:

[0042] Separate piercing and separate blasting: Through geological survey, different types of ores are perforated and blasted separately. According to the analysis of blast hole test data, different types of explosive piles are formed, hematite, magnetite and iron carbonate, among which iron carbonate belongs to For refractory ore, ac...

Abstract

The invention discloses a dynamic ore matching optimization method for a mined ore, and belongs to the technical field of ore matching between mining and ore dressing. According to the method, from the production practice, ore matching is carried out according to the practical situations of a concentration plant and a stope; an ore matching plan is released through the ore matching ratio; and dynamic tracking on the grade, the ore property and the magnitude of a refractory ore is achieved in an ore matching process, so that the details of the ore matching process can be seen in the concentration plant in real time. By ore matching software, an actual process of dynamic curing production and dynamic grade calculation, connection of automobile transportation and railway transportation and connection of a mining link and an ore matching link are achieved; the actual ore grade is calculated through a neutral ore matching model; validation whether ore matching is carried out on the mined ore or not according to the ore matching proportion requirements by the concentration plant is facilitated; stable and normal production of ore dressing is ensured; the property, the grade and the magnitude of the ore in each process of the ore dressing link and the ore matching link are ensured; and the requirements on basically stable grade and washability of the ore iron in the concentration plant are met.

Description

technical field [0001] The invention belongs to the technical field of ore blending between mining and mineral dressing, and in particular relates to a dynamic ore blending optimization method for mining ores. Background technique [0002] The so-called ore blending, also known as ore quality neutralization, is to meet the requirements of ore quality indicators. For ores with different grades or different ore properties, they are matched with each other in proportion to make them evenly mixed. Reasonable ore blending has always been a process for dressing plants The urgent requirements of the stope; [0003] In recent years, the cost pressure of mines has been high. From the strategic height of sustainable development, it is necessary to consider the geological grade of the ore, the grade of the mining, the grade of the selection, the grade of the concentrate, and the grade of the furnace; Production should strive to achieve the goal of dynamic optimization of ore blending;...
