The Congo (DRC) Kamoa-Kakula copper mine is Zijin Mining's blockbuster project to achieve leapfrog growth. The construction project of the 3.8 million-ton ore processing plant in the second phase of the project is advancing rapidly, with about 93% expected to be completed by the end of January, and will enter the trial run stage with materials in April this year. The overall progress is significantly ahead of the original second quarter. Based on a 100 per cent equity, the planned 2022 target for the Kamoa-Kakula copper mine is to produce 29-340000 tonnes of copper metal.

Sandvik was founded during the great development of metallurgical industry. In 1862, Göran FredrikG ransson and his experienced engineers and employees successfully produced steel for the first time using the Bessemer steelmaking process. Swedish steel quickly became a hot commodity because of its high quality. Rock drills were the first tools to actually use this steel, and Sandvik began supplying it in the 1870 s. Today, Sandvik is proud to carry on this time-tested tradition, which has given the company a unique manufacturing capability-the self-production of rock drilling rigs.

In September 2021, the commander of the Guinean special forces, Colonel Mamady Dunbuya, staged a military coup, declaring that his forces had seized power in the country and seized President Alpha Conte. At the same time, the Guinean government was formally dissolved, the constitution was repealed, and the land and air borders were closed. This is the first time in 13 years that Guinea has again undergone a regime change in the form of a coup d'état. The coup leader, Dunbuya, was the first to appease investors from various countries, promising to abide by existing bilateral and multilateral agreements, lift curfews in mining areas and ensure the continued operation of mining enterprises. It is hoped that foreign-funded enterprises will not be affected by the changes in the situation in Guinea and will maintain normal production.

With the rapid development of China's economic construction, the exploration and development of mining resources has become one of the important industrial projects. The national "Eleventh Five-Year" development program clearly states that in the 21st century, my country's geological exploration engineering technology should be broadened to a wider field, and geological exploration equipment should be developed in the direction of high mechanization, lightness, automation, and international generalization. Geological exploration drilling tool is a product type of rock drilling tools. At present, various geological exploration drilling tools commonly used in China are shown in Figure 1.
