Conquest the world's problems!Shandong large -diameter mine quick drilling rescue test successful

During mine rescue, large -caliber -oriented fast drilling technology is a worldwide problem. Recently, the test of the "Large -caliber Direct Drilling Technology and Application Project" was successfully conquered by the "Large -caliber orientation fast drilling technology and application project" undertaken by the Shandong Mining Drilling Emergency Rescue Center, which exceeded this problem.

The test location of the project is located in the Jining Economic and Technological Development Zone. For the first time, it has been used to build a 711 mm large -caliber rescue test well in the domestic one -time hole -forming process. The depth reaches 402 meters and the shaft bottom shift is 0.45m. The full -hole pure drilling time is 14 days, of which the air -based anti -circulation process is only 192 hours.

"Previously, most of the mining rescue quickly drilled to the accident area through a small -caliber drill, and carried out life detection, communication establishment, and transportation and transportation through the hole, which is difficult to achieve the ideal rescue effect. The life capsule can be saved quickly. "Wang Xiaoqin, the Secretary of the Party Committee and Captain of the Second Exploration Team of the Shandong Coalfield Geological Bureau, introduced that the efficiency of the drilling of the project is two to three times that of normal drilling. In response to the ability of the province and the surrounding provinces, municipalities and mines, the province will be promoted to the provincial coalfield Geological Bureau in accordance with this drilling experience to promote the next time.
