Drainage project

(1)In 2015, "Research on Karst Groundwater System and Prevention Water of Laohudong Phosphate Mine in Weng'an County, Guizhou Province" won the first prize of engineering survey results in non-ferrous metal construction industry. The mine has large reserves and high grade, but the problem of water inrush and flooding seriously restricts mine development. The company provides technical support for mine mining through the mode of "survey + design + water prevention research", and the mine has entered the construction stage at present. ⑵ "Evaluation of Hydrogeological Conditions of Duancun-Leigou Bauxite Mine and Research on Water Prevention and Control Technology in Production Stage" completed in 2017 won the second prize of Excellent Engineering Consulting Achievements of China Nonferrous Metals Construction Association. Through the research on the change law of groundwater flow field in recent years, the project team has constructed a groundwater numerical model with higher simulation degree, and simulated the characteristics of groundwater flow field in different mining conditions and periods, which is of great significance for guiding the water prevention and control work in various production stages of mines.

Sampling design project of ore processing performance test of copper polymetallic ore in the middle reaches of Laling Zaohuo

Sampling design project of ore processing performance test of copper polymetallic ore in the middle reaches of Laling Zaohuo

In the sampling design project of ore processing performance test of copper polymetallic ore in the middle reaches of Laling Zaohuo, according to the division of component interval, frequency and frequency statistics of mineralization zone in mining area, the designed sampling points and grades are selected in low, medium and high schools, and the proportion of sampling points basically conforms to the frequency distribution. Considering the representativeness of the main components Cu, Mo and Au, 19 sampling points were arranged, of which 17 were taken in the borehole core during the general survey and detailed investigation, and 2 were taken in the mining pit CK1. The sampling points are distributed in different exploration lines and different depth positions, which can well meet the representativeness of spatial distribution of ore samples. Compared with the average grade of mineralized zone, the average grade of Cu and Mo decreased by 8.86% and 6.46% respectively. According to experience, the permissible relative error of general nonferrous metal deposits is-15% ~ +15%, and the effect of-15% ~ 0 is the best. Both Cu and Mo are within the optimum range of sample grade fluctuation. After the sampling design was implemented, representative test samples were provided for the ore processing performance test of copper polymetallic ore in the middle reaches of Laling Zaohuo, which met the test needs.

Demonstration of industrial indicators of Chating copper deposit in Anhui Province

Demonstration of industrial indicators of Chating copper deposit in Anhui Province

Chating copper deposit in Anhui Province is a concealed large porphyry copper-gold deposit. The natural type of ore is veinlet disseminated gold-bearing copper ore, and the industrial type of ore is primary sulfide gold-bearing copper ore. The general survey of the mining area lasted from 2009 to 2018, with a cumulative drilling footage of more than 46,100 meters. In order to determine a reasonable industrial index and provide a target area for detailed investigation, the company carried out the demonstration of industrial index of copper deposit in Chating mining area. According to the mineral resources and external construction conditions of the mining area, the mining scheme and beneficiation scheme are demonstrated, and the technical and economic analysis and evaluation are carried out. The recommended industrial indexes are in line with the actual situation of the mining area, which provides a basis for delineating copper polymetallic ore bodies and estimating resources in the mining area. The project won the third prize of excellent engineering consulting.

The due diligence project of resources in Bofa bauxite area, Guinea

The due diligence project of resources in Bofa bauxite area in Guinea undertaken by our company, Through field investigation, engineering verification, dissolution test and three-dimensional geological modeling, the metallogenic conditions, reliability of exploration data, dissolution performance of ore and resource amount of the mining area are systematically evaluated, which provides a crucial decision-making basis for the development and feasibility study of the project. The project won the third prize of excellent engineering consulting.

Geological prospecting research of Zara gold mine in Eritrea

Geological prospecting research of Zara gold mine in Eritrea

Zara gold deposit in Eritrea is a part of Zara-Bisha metallogenic belt, one of the two main metallogenic belts in Eritrea. On the basis of judging the previous geological data, the company has carried out remote sensing geochemical interpretation, field investigation and anomaly verification, anatomy of typical ore deposits, etc., summarized the mineralization characteristics, ore-controlling factors and genesis of gold deposits in the mining area, and delineated a number of target areas with prospecting value.

Infrastructure exploration of Guinean Boffa bauxite mine

Infrastructure exploration of Guinean Boffa bauxite mine

The design scale of Guinean Boffa bauxite mine is 12 million tons/year. Under various harsh conditions such as rampant overseas epidemic and local election turmoil, the project team of the company strictly guards against death and organizes scientifically. The accumulated drilling footage is more than 30,000 meters, and the amount of bauxite ore transported abroad is about 52 million tons, which provides reliable resource reserves for the sustainable development of the mine. The project adopts spiral waterless drilling technology, which significantly improves the exploration efficiency on the premise of ensuring the drilling quality. At the same time, the three-dimensional geological model of the deposit is established by using three-dimensional software, which greatly facilitates the production management and stope ore matching of the construction unit, and shows the rich overseas construction experience and first-class laterite bauxite exploration technology level of the company.

Bauxite exploration in Xiaolongmiao mining area, Mianchi County, Henan Province

Bauxite exploration in Xiaolongmiao mining area, Mianchi County, Henan Province

Bauxite exploration in Xiaolongmiao mining area, Mianchi County, Henan Province is one of the large-scale bauxite exploration projects completed by our company. The lithology of strata in mining area is complex, and there are many mined-out areas. In the process of exploration and construction, the company took the lead in adopting hydraulic thin-walled drilling tool rope coring technology in China, which has small construction area, convenient relocation and high core recovery rate. Combined with drilling work, transient electromagnetic method (TEM) is used to comprehensively explore mined-out areas, which can intuitively and accurately reflect the distribution of underground mined-out areas and provide more accurate guidance for future mining work. This project won the third prize of non-ferrous metal geological prospecting achievements of China Nonferrous Metals Industry Association in 2020.
