Sichuan Provincial Land and Mining Bureau 106 Geological Team Geotechnical Construction Company: "Pioneer" of geological drilling in the depths of the mountains

The back of the back is far from prosperous, just to find the mine collection; with heavy drilling equipment in the inaccessible plateau hinterland, thorns cliffs, and even yellow sand rolling Gobi, the cold, cool summer, war wind sand ... This is Sichuan Sichuan Provincial Land and Mineral Bureau 106 Geological Team Geotech Construction Corporation (hereinafter referred to as "Rock Land Construction Company") employees' true portrayal.

Since its establishment in 1995, all employees of the Geotechnical Construction Corporation have not been afraid of suffering, not afraid of tiredness, overcome all kinds of difficulties, and successively completed the exploration and development of important mineral resources such as vanadium titanium magnet and graphite ore. For more than ten years, the rock and soil construction company has completed a total of more than 350,000 meters in the total of solid rock core drilling. The construction quality has been better or more, and the high -quality drilling rate has reached more than 85%. The honorary titles such as the Pioneer "" China Vancanic Titanium Capital Exploration Pioneer "have been repeatedly rated as" advanced collective "and" advanced collective collective collective ". This year, the Rock and Land Construction Corporation also obtained the "National Workers Pioneer", which is the only collective for the "National Workers Pioneer" this year.

"We also have to roll up our sleeves and work hard, turn this glory into motivation, and continue to carry forward the spirit of the iron army." Facing the honor, the employees of the rock and soil construction company are proud of It will continue to forge ahead, strive to be the pioneer of the industry, and blow the "pioneer" of geological drilling.

Hard struggle shows the color of geological people

"Happiness is struggling, and the dream of geological people must be achieved by struggle." At the rock and soil construction company, whether it is leaders or ordinary employees, whether it is old employees with white hair or new employees who have just entered the company, they are in their hearts. Have a simple dream: contribute to the mining business.

In order to realize this dream, for many years, they have not forgotten their original intentions, they are not afraid of harsh environment and difficult conditions. , Strive on the front line.

"This is a critical juncture. Everyone focuses on attention." At the drilling construction site, the huge roar from the drill head was dug at the ground. Mask, wearing orange work clothes covered with mud and oil, leads several young employees for drilling operations ... Not far away is a simple tent built by several tent rods and canvas. This is also temporary during their construction operations. Where to rest. "The rig can not stop as soon as the drill is opened. We all have to work in three shifts."

In the Geotechnical Construction Corporation, it is normal for the "passing bands" form that is always standing in front of the team members and technical backbones to lead the team to overcome difficulties. "The working environment of geological exploration is difficult, and the situation is complicated. There are us 'old people' with them, and everyone is not panicked." In Li Long's view, this "passing band" makes the "three glory" of the geographical survey people " Live in spiritual salary.

In October 2019, at the survey of the Sichuan -Tibet railway construction company, the rock and soil construction company should conduct drilling construction at the Kazila Mountain at 4,600 meters above sea level. At that time, the Sichuan -Tibet Plateau sealed mountains, and the temperature was as low as minus 26 ° C. In order to ensure the smooth progress of the Sichuan -Tibet Railway survey, the technical backbone of the Geotechnical Construction Corporation led the construction personnel to continue to build operations in low temperature and low oxygen environments. Because drilling operations needed a lot of water, the temperature at that time was so low that the water could make the water instantly ice. The construction workers go to the water source to break the ice and remove the water every morning, and use resistance wire heating and wrapping insulation cotton to ensure the normal water supply of water pipes. Due to long -term outdoor low -temperature operations, the hands of the construction staff were cracked to varying degrees, but none of them complained. "Choosing persistence is the importance and urgency of the current task. This is also the spiritual inheritance of our local survey." Construction staff said. With everyone's efforts, the drilling construction tasks are completed as scheduled.

Geological drills can't be a little bit sloppy

"Geological drilling is a geological engineering for reliable evaluation for geological and mineral resource parameters. It cannot be sloppy." Peng Xiayang, manager of the geotechnical construction company, said. In September 2018, the Rock and Land Construction Corporation began to explorate the largest graphite mine in the southwest, the largest graphite mine in the southwest, Panzhihua City. During the exploration, due to the severe leakage of the drilling strata in the mining area, the risk of production accidents in the process of drilling in and internal pipeline delivery during the drilling process increased sharply. To this end, Li Long led the technical team to work in the wild for several months. During the day, they collected relevant data at the exploration site, returned to the station to sort out the information at night, and comprehensively analyzed the principles and facing problems of the internal management of the device. At the same time, actively ask relevant experts to find the cause, and improve the internal management and delivery device. After continuous efforts, the problem was finally solved smoothly.

During the construction period, the units of the geotechnical construction company continued to explore and innovate the construction technology of a portable hydraulic drilling rig to improve the exploration efficiency. 103 drills were completed within 6 months. Raise to 1038.5 meters per month. After exploration, the reserves of Grapemite ore in Zhongba Mine in Renhe District were nearly 250 million tons, and the minerals were nearly 15 million tons, which was tens of billions of billions. The project was selected as the list of outstanding achievements of the Ministry of Natural Resources to find the excellent achievement of the strategic operation of the Ministry of Natural Resources and became the iconic project of the construction of a portable hydraulic drilling machine to fully launch a portable hydraulic drilling machine construction and improve the construction efficiency. This is only one of the many projects for geotech construction companies. Since 2010, geotechnical construction companies have focused on important mineral resources such as vanadium titanium magnetite and graphite mine. While refining the Panxi area, they have carried out geological mining work in Tibet, Qinghai, Xinjiang and other places. Leaning and improving the level of drilling technology

"Geological drilling work is also a science and technology work." In Peng Xiayang's view, under the new environment and new requirements, drilling technology, methods, and craftsmanship must keep up with the pace of the times. "The technology set by the drilling construction process has been well used in the process of drilling construction for many years. Energy consumption, create a green construction site. "

In recent years, the geographical survey industry has actively implemented the development concept of "green water and green mountains is the golden mountains and silver mountains", and the green survey work has been launched. The portable full -hydraulic rock drilling rig has gradually been promoted in the drilling construction due to its modularity, the small area of ​​the machine, and the small excavation area. However, in practice, the technicians of the geotechnical company found that the portable full -hydraulic rock rig drilling machine cannot normally use circulating drilling fluids like traditional vertical shaft rigs due to structural restrictions. Simple precipitation or "disposable drilling liquid" is usually used at the scene. However, the "disposable drilling solution" has a large amount of emissions, the comprehensive cost is high, and the risk of polluting water sources and easy to eat livestock.

To solve this problem, in early 2021, the technical personnel of the geotechnical construction company began to develop a portable full -hydraulic rock core drilling rig drilling system- "mud will not fall" circular system. The development and development of the system can improve the solid -phase treatment effect of drilling liquid within a limited space range, improve the performance of the flushing solution, reduce the consumption of the rinse solution by 36%, increase the liquid repetition rate of 32%, reduce the discharge of waste pulp by 42% , Efficiently used water resources. At the same time, the drilling efficiency has also improved by 18%, and the service life of equipment and drills has been improved. At present, the "mud does not fall" circular system has been used in the census project of Tongde Grying Mine in Renhe District, Panzhihua City. Essence

In addition to promoting the improvement of green survey technology, the rock and soil construction company also reduces the risk of production accidents during drilling construction through innovative drilling technology. In the geological core drilling, the mainstream water stops used in the current pressure water test are in the application application of deep or ultra -deep -hole pressure water tests. Diamonds have increased the risk of production accidents. To this end, the innovation of the geotechnical construction company adopts double -gas (water) water -stop capsules as a water stop device for deep and ultra -deep pore pressure water tests, and the first -hole experimental dual -stop water capsules The test process of the well mouth greatly reduces the next number of drill rods.

"We must also continue to strengthen our cohesion and combat effectiveness, continue to fight in the north and south of the motherland to find mines and serve the geology." Peng Xiayang said that all employees of the Rock and Land Construction Corporation will continue to carry forward The excellent tradition and style of self -confidence, self -improvement, and Yongchuang, and strive to become a high -quality team that is superb, strong, united, and dedicated to the economic construction of social development.
