The dual-arm tunneling drill rig has a maximum effective drilling cross-sectional area of 112 square meters.

The Boomer 104 is a four-wheel drive single-arm drilling rig, suitable for drilling in narrow spaces. It is mainly used for tunnel engineering and underground mining excavation operations, effectively drilling cross-sectional areas of 12 to 30 square meters.

According to a report from Mining.com, preliminary statistics released by the U.S. Geological Survey (USGS) indicate that global lithium production from mines in 2021 was 100,000 tons (excluding the United States), an increase of 21% compared to 82,500 tons in the previous year.

In Hubei, there is a mine, which is the first large open-pit iron mine in modern China to be mined using machinery; there is a mine that was once the "granary of steel" for New China, the only iron mine that Chairman Mao Zedong inspected, a place he said he would visit even if he had to ride a donkey; there is a mine that, from its reconstruction in 1958 to 2012, produced enough iron ore to be equivalent to the steel needed for 220 sections of the Beijing-Kowloon Railway, the copper extracted could be made into wires long enough to stretch from the Earth to the Moon, and the gold extracted could be made into 1.5 million necklaces weighing 10 grams each... providing valuable wealth for the country's industrial revival and economic development.

In September 2021, Colonel Mamady Doumbouya, commander of the Guinea special forces, launched a military coup, announcing that his troops had seized control of the country and detained President Alpha Condé. At the same time, the Guinean government was officially dissolved, the constitution was abolished, and land and air borders were closed. This marked the second change of power in Guinea through a coup after 13 years. The coup leader Doumbouya immediately reassured investors from various countries, promising to adhere to existing bilateral and multilateral agreements, lift the curfew in mining areas, and ensure that mining companies could continue operations. He hoped that foreign enterprises would not be affected by the changes in the situation in Guinea and would maintain normal production.

The trenching machine is a large construction machinery used for quickly excavating trenches for pipeline installation in soft soil and loose strata.
