玲珑金矿东山塌陷区的锚注联合治理

The Combination Harnessing of Anchoring and Grouting to The Subsidence Area of East Mountain of Linglong Gold Mine

对于覆盖碎石性杂填土的采空区地表塌陷问题,在地质雷达探测研究的基础上,文章提出了以锚固为主的锚注联合治理方法,解决了在碎石性杂填土中依靠简单的设备工艺打孔、护孔、注浆、穿锚等技术难题,对于急倾斜中厚以下矿体采空区冒落引起的地表塌陷治理具有重要意义。

For the surface subsidence problem of the mined-out area covered with crushed rocks bankette, based on the exploration and research of geologic radar, this paper put forward the combination harnessing method of anchoring and grouting in which the anchoring is primary. This method resolved technology problems, such as boring, protecting hole, grouting and anchoring in the crushed rocks bankette by simple equipment and technology. It also has important significance to the harnessing of surface subsidence caused by the mined-out area falling of heavy-inclined and deep ore body.
