Civil Building Survey of Jinxing Jiayuan Geotechnical Engineering Survey Project

Civil Building Survey of Jinxing Jiayuan Geotechnical Engineering Survey Project

The "Jinxing Jiayuan Geotechnical Engineering Survey" project completed in 2018 includes five high-rise buildings. The survey work is carried out by combining drilling, in-situ test and indoor test, and the survey report with reliable data is provided. After completion, the buildings are in good service condition.

Curtain works

Curtain works

The project of "Section IV of Reservoir Protection Project of Datengxia Water Control Project" undertaken by the Company, Anti-seepage curtain (divided into east and west curtains) is the longest mine curtain under construction in China with the largest investment. Since 2016, the Company has provided a complete set of services including survey and design, grouting test and technical consultation. At present, the east curtain has been successfully implemented and the water shutoff effect is remarkable.

Mining under pressure

Mining under pressure

In 2008, "Research on Water Prevention and Control in Underground Mining of Lindai Bauxite Mine in Guizhou" won the third prize of science and technology in China's nonferrous metal industry. Many accidents of water inrush, mud inrush and well flooding occurred in the production process of the mine, which caused the mine depth extension to stagnate. After carrying out supplementary hydrological investigation, our company put forward the scheme of "surface + underground joint prevention and control", which successfully solved the hydrogeological problems affecting the development of deep resources. At present, the mine project has been successfully developed to the lowest production elevation.

Drainage project

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, 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.
