| 中文摘要: |
| 胶东金青顶石英脉型金矿是我国矿体延深大于延长的代表性的特大型金矿床,矿体侧伏延深已控制1320 m,属于典型的构造控矿类型。目前矿区开拓深度达900 m,采矿深度达805 m,由于地压随采矿深度的增加而加大,脉外巷道出现大面积的挤压裂缝或局部塌落,严重影响了矿山的正常生产。研究矿区深部地压形成机理,改进现存的采矿工艺,以适应深部特有的地压活动规律,从而维持矿山正常持续生产。 |
| 英文摘要: |
| The Jinqingding gold deposit located in Jiaodong, Shandong Province, is a super-large sized quartz vein type gold deposit controlled by the fault, it is well-known for the dipping extension of the orebody larger than its strike length. Currently, the controlled dipping depth reaches 1320 meter below. The mining development depth is up to 900 m, and the mining operation has reached to 685 m deep. With the mining depth increased, the ground pressure was increased too and a serious extrusion cracks and local collapses happened in the tunnels outside of the veins, which has severely affect the normal mining operation. It is vital to study the mechanism of ground pressure formation in the underground mining operation, and thus propose to adapt the existing mining technology to the rules of underground ground pressure, and to ensure the sustainable mining operation. |
