90年代的第一个春天里,第三届全国采矿学术会议在长沙市召开了。本刊编辑部谨向参加会议的全体代表致以衷心的祝贺！向全国数百万矿业大军致以热烈的问候和崇高的敬意！ 1990年我国矿业界还将负责举办第十四届世界采矿学术会议,我们借此机会预祝会议取得圆满成功,为推动我国矿业技术进步,加速国际矿业技术交流作出应有的贡献! 回顾过去四年来我国矿业方面取得的进步和成就,我们感到由衷的高兴。1989年国家决定在治理整顿中对能源、交通、原材料等部门实行适度倾斜政策,这为矿业部门的顺利发展提供了良好的条件。 In the first spring of the 90s, the 3rd National Conference on Mining was held in Changsha. Our editorial department would like to extend our heartiest congratulations to all the delegates attending the meeting! Give warm greetings and high tribute to millions of Chinese mining troops! In 1990, China’s mining industry will also be responsible for hosting the 14th World Conference on Mining, and we would like to take this opportunity to wish the conference a complete success and make due contributions to the promotion of China’s mining technology and the acceleration of international mining technology exchange. We are sincerely happy to see the progress and achievements made in the mining industry in our country in recent years. In 1989, the state decided to moderately favor energy, transportation and raw materials departments in the course of rectification and rectification, which provided favorable conditions for the smooth development of the mining sector.
