| 中文摘要:龙山金锑矿是位于湖南湘中地区龙山穹窿核心部位最具代表性的金锑矿床之一。由于劈理发育,在以往施工的所有钻孔都存在严重的偏斜现象。在查阅以往钻孔施工资料及相关参考文献的基础上，对造成钻孔偏斜原因及规律进行了统计分析，发现龙山矿区钻孔偏斜距离与钻孔设计孔深、岩层劈理、施工工艺等因素有关。提出了可以采用移动孔位法、改变倾角法、扭转安装法和采用合理的施工工艺等预防措施，减少了钻孔偏斜强度，提高了施工效率，保证了钻孔质量。 |

| Abstract:Being located at the core area of Longshan dome, Longshan gold antimony deposit is one of the most representative gold antimony deposits in the central Hunan Province. All the boreholes in the previous construction are deviating seriously due to cleavage development. Based on the review of previous borehole data and related references, the statistical study and analysis on the reasons which caused borehole deviation and the deviation regularities are made, it is found that the borehole deviation distance is connected with borehole design depth, rock cleavage and construction technology. The prevention measures, such as hole location moving, inclination angle changing, vertical shaft azimuth adjusting and reasonable construction technology adopting, are put forward to reduce the borehole deviation, improve construction efficiency and ensure the borehole quality. |
