Development Status of Large-Diameter Drilling at Home and Abroad
Abstract: Large-diameter drilling (also known as shaft sinking by drilling method) originated in Western Europe. After technological iterations in various countries, it has been widely applied and relevant equipment developed in the United States, the Soviet Union, Germany and other countries. China conducted trials in 1958 and drilled its first mine shaft in 1969, gradually achieving independent development and expanding its applications to national defense, high-rise buildings, sewage treatment and other fields.
