中国大陆深孔地质钻探科研规划（草案）讨论会于1989年8月25日在京召开。会议由地矿部勘查技术司司长李常茂主持，刘广志教授级高工作了《科学深钻规划（草案）说明》和学术报告，出席会议的共15人，认真讨论了规划修正草案。科学深钻系人类登月壮举后的又一重大科学成就，引起世界各国的重视：美国于1960年相继成立联合海洋地球深层取样机构（JOIDES）和深海钻探计划（DSDP）。已在海上钻孔1092个，最大水深6247m，水下进尺1412m，钻入洋底玄武岩深达583m。1974年在俄克拉荷马钻成世界第一口9583m的科学深井。
China deep hole geological drilling scientific research (draft) seminar was held in Beijing on August 25, 1989. The meeting was chaired by Li Changmao, Director of the Exploration and Technology Division of the Ministry of Geology and Mineral Resources. Prof. Liu Guangzhi worked for “Science Depth Planning (Draft) Description” and academic report. A total of 15 people attended the meeting and seriously discussed the draft plan revision. Scientific Deep Drilling Department Another major scientific achievement after the human being went to the moon has aroused the attention of all countries in the world. In 1960, the United States established JOIDES and Deep Sea Drilling Program (DSDP) in succession. 1092 holes have been drilled at sea, with a maximum water depth of 6247m and an underwater footage of 1412m. Drilling into the ocean floor basalts is as deep as 583m. Drilling into the scientific deep well of 9583m in the world in Oklahoma in 1974.
