快速建井技术装备现状及发展方向

Present Status and the Development Orientation of Rapid Mine Construction Technology and Equipment

文章简要陈述近些年来我国在应对地质及水文地质条件复杂地区的矿井建设,发展起来的地层改性技术冻结法、地面注浆技术及取得的成就,在快速建井技术、工艺及装备方面,对冻、注、凿平行作业发展,新研究的钻注平行作业工艺,千米深井凿井技术及装备进行了论述说明,对于以机械破岩为核心,减少井下作业人员的"一扩成井"快速钻井法凿井新技术、大直径反井钻井凿井新工艺进行重点说明。文章还对建井技术发展进行展望,并介绍了目前正在进行的矿山竖井掘进机、斜井沿轴线冻结及非悬吊凿井装备配套研究项目。

The paper briefly states the mine construction technology in dealing with the complex geo-logical and hydrogeological conditions in recent years in china ,such as ,the developing ground-modifi-cation freezing method ,pre-grouting on the ground technology and their achievements .This paper dis-cusses the development of parallel working of freezing-grouting-shaft sinking ,new type drilling-grou-ting simultaneous operation technology and 1 000m deep mine shaft construction in the aspect of rapid shaft construction technology ,process and equipment.In addition ,it focuses on the new rapid drilling mine construction technology of “one borehole enlargement into one shaft”and the new crafts of large diameter raise boring upward excavation method based on mechanical breaking rocks and reducing un-derground workers.The paper also makes a outlook about the development of shaft construction tech-nology ,and introduces the present research project of mine full face shaft boring machine ,slope along the axis of freezing and non-suspension drilling equipment.
