Embodiment 1

[0064] The first embodiment is the basic mining process of this application.

[0065] A. Built-in mine measurement data in the fine mining location server. The mine measurement data includes the surface digital elevation model (DEM) of the entire mining area and the mining bioprospecting data. The mining bioprospecting data includes the ore grade and ore distance distributed under each location of the mining area. Information on the depth of the surface and the thickness of the ore body;

[0066] B. Open the fine mining terminal and connect with the GNSS differential base station and the fine mining location server. The fine mining terminal receives the differential correction data of the GNSS differential base station and calculates the position by itself, and sends the precise bucket position to the fine mining location server;

[0067] C. The fine-mining location server receives the bucket position and sends the bio-exploration data of the current location to the fine-mining termi...

Embodiment 2

[0070] The second embodiment is the mining process that reminds the boundary information.

[0071] A. Built-in mine measurement data in the fine mining location server. The mine measurement data includes the surface digital elevation model (DEM) of the entire mining area, the mining area bioprospecting data and the boundary information agreed by the mineral rights. The mining area bioprospecting data includes each location of the mining area Information on the grade of the ore distributed below, the depth of the ore from the surface, and the thickness of the ore body itself;

[0072] B. Open the fine mining terminal and connect with the GNSS differential base station and the fine mining location server. The fine mining terminal receives the differential correction data of the GNSS differential base station and calculates the position by itself, and sends the precise bucket position to the fine mining location server;

[0073] C. The fine-mining location server receives the bucket pos...

Embodiment 3

[0079] The third embodiment is the mining process in which the fine mining location server updates the biological prospecting data in real time.

[0080] A. Built-in mine measurement data in the fine mining location server. The mine measurement data includes the surface digital elevation model (DEM) of the entire mining area and the mining bioprospecting data. The mining bioprospecting data includes the ore grade and ore distance distributed under each location of the mining area. Information on the depth of the surface and the thickness of the ore body;

[0081] B. Open the fine mining terminal A and connect to the GNSS differential base station and the fine mining location server. The fine mining terminal A receives the differential correction data of the GNSS differential base station and calculates the position by itself, and sends the precise bucket A position to the fine mining location server ;

[0082] C. The fine-mining location server receives the position of bucket A and ...

Abstract

The invention provides a surface mine fine mining system adopting a GNSS (Global Navigation Satellite System) technology and a surface mine fine mining method. The surface mine fine mining system comprises at least one GNSS difference base station, a fine mining position server and a plurality of fine mining terminals, wherein the fine mining position server is internally provided with mine measurement data; and the fine mining terminals are used for calculating to obtain current positions of fine mining terminal scraper pans according to difference correction data provided by the GNSS difference base station and feeding back scraper pan position information to the fine mining position server. By utilizing the surface mine fine mining system, intuitive ore body thickness / depth / quality information is provided, accurate guidance is provided for mining operation of a digging operator, ore body condition is updated in real time, and the surface mine fine mining system also has the effect of early warning cross-border mining behaviors.

Description

Technical field [0001] The present invention relates to the technical field of mineral collection, in particular, to a fine mining system and a mining method for open-pit mines using GNSS (Global Navigation Satellite System) technology. Background technique [0002] The main mining tool in open-pit mines is a mining backhoe. The current mining model is that the Ministry of Mines formulates mining tasks based on existing prospecting data and measurement data, and delimits mining areas and mining targets every day. Each mining excavator arrives at the mining site to carry out excavation operations according to the agreed target in advance. [0003] There are two problems with this mode: First, it is impossible to judge how deep the dig should be each time, which can easily lead to missed mining and waste of mineral resources, or excessive mining leads to a decline in ore grade. Because the excavator's excavation site continues to advance as the excavation work progresses, it is imp...
