| 摘 要： | 充填采矿法是现代矿山广为采用的高效无废采矿法,充填钻孔是充填系统的＂咽喉＂。充填钻孔的使用寿命因素除了输送介质的物理特性、系统的力学特性、管道材料特性外,钻孔偏斜等施工质量成为决定性因素。充填倍线指标是充填钻孔设计的主要依据。充填钻孔施工方法与工序质量控制是保证充填孔质量的关键。在分析了影响充填钻孔使用寿命因素和充填钻孔施工难点的基础上,总结和介绍了充填钻孔的施工方法和质量控制措施。

| Abstract: | Backfill drilling is a widely adopted high efficiency mining method in modern mine,borehole backfilling is the key in backfilling system.Beside the physical property of medium transported,the mechanical property of the system and the material property of pipeline,the construction quality such as borehole deviation and some others are the decisive factors to service life of the backfilling borehole.The filling times line is main basis for design of backfill drilling hole,the construction method and process quality control are the key to ensure the quality.Based on the analysis on the factors affected on service life of backfill drilling hole and the construction difficulties,the paper summed up and introduced the construction method of backfill drilling hole and the measures for quality control. |
