Problems solved by technology

[0006] Prior art 1 realizes the control of mine grade through the guidance of the excavator operation. Mining is only a link in mine production operations, but ore blending is a comprehensive process flow. Prior art 1 does not consider the amount of ore, grade, and equipment Due to constraints such as production capacity and spatial location, this method is not yet suitable for complex and autonomous transportation scenarios such as unmanned transportation in open-pit mines.
[0007] Prior art 2 is aimed at the scene of underground ore mining, and operates in the form of rail locomotives, which requires the participation of operators at the ore loading point or on the electric locomotive. Prior art 2 does not clearly describe the ore distribution model, and the ore loading point during scheduling The ore grade is known (the preset ore grade ore blending scheduling parameters include the marshalling train number, the wagon serial number corresponding to the train number, the ore loading point number, and the ore grade and ore capacity tracking curve corresponding to the ore loading point), Therefore, the existing technology 2 cannot meet the open-pit mine scene and the ore blending demand in the case of unmanned transportation in the open-pit mine
[0008] Prior Art 3 The dynamic ore blending model of mining ore is aimed at specific ores, and the ore specifically refers to hematite, magnetite and iron carbonate, and the ore blending model is also aimed at the ratio of these three kinds of ores. Not limited to one or a fixed type of ore, the existing technology 3 has certain limitations and cannot be integrated into the unmanned transportation scene of open pit mines

Embodiment 1

[0078] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0079] (1) Mathematical model of ore blending

[0080] The construction of the mathematical model of ore distribution is explained here.

[0081] For example, in the generation of bauxite, assuming that there are 2 explosive piles that can be produced, the composition of the explosive ore is as follows:

[0082]

[0083] Among them, the grade of aluminum (A1) in explosion pile 1=mass of aluminum element / M1, and the grade of silicon (Si)=mass of silicon element / M1.

[0084] Requirements: The Al grade of the ore in the crushing station (discharge port) is controlled at A±5%, and the Si grade is controlled at S±2%. (where A and S are the grade values ​​that need to be controlled, which are known quantities; ±5% and 2% a...

Embodiment 2

[0157] (1) The technical solution of the present invention has constructed a kind of ore blending scheme of the unmanned transportation system of open-pit mines. First, construct constraint functions respectively according to the explosion pile parameters, unloading point parameters and ore blending grade indicators. According to the aforementioned three constraint functions and the minimum deviation between the mixed ore grade and the target grade at the unloading point to construct a mathematical model of ore blending; then, according to the ore blending production target, the preset ore output ratio threshold and the above three constraint functions to solve the ore blending mathematical model, each The ore output ratio of each explosive stack, and generate an ore allocation plan including the daily average ore output of each explosive stack according to the ore allocation ratio; moreover, convert the ore allocation plan into the ratio of the number of ore loading vehicles, b...

Abstract

The invention discloses an ore blending scheduling method of a strip mine unmanned transportation system. The ore blending scheduling method comprises the following steps: acquiring muck pile information, unloading point information and ore blending target information participating in ore blending; based on the muck pile information, the unloading point information and the ore blending target information, solving a pre-constructed ore blending mathematical model to obtain an ore blending scheme; according to the ore blending scheme, determining the number proportion of muck-pile ore loading cars; and pairing unmanned mine cards of the strip mine unmanned transportation system according to the proportion of the number of the muck pile loading mine cars and the preset information of the shoveling equipment at the muck pile, and generating an ore blending scheduling plan. According to the ore blending scheduling method of the strip mine unmanned transportation system provided by the invention, the ore blending scheduling method which is friendly in interaction, simple and convenient to operate and short in ore blending calculation time consumption, is tightly combined with the unmanned transportation system and supports flexible adjustment and dynamic proportioning is provided.

Description

technical field [0001] The invention relates to an ore blending scheduling method for an unmanned transportation system in an open-pit mine, and belongs to the technical field of mining or quarrying scheduling. Background technique [0002] During the process of deposit formation and ore body regeneration, the distribution and concentration of useful components in the ore body are naturally variable and unstable. As the process of deep mining of rich ore becomes more complicated, lean ore and refractory ore in open-pit mines are gradually mined. In order to ensure that the mined ore can meet the quality standards required by the utilization department, it is necessary to mix ores of different grades, and the ore blending work has become the top priority. [0003] The so-called ore blending is also called ore quality neutralization / equilibrium. It is planned and purposeful to mix ore with different grades in proportion to make it as uniform as possible. It aims to reduce the...
