摘要
充填体质量的好坏决定井下回采环境的好坏,而充填体质量检测必须要进行充填体取样。针对传统充填体取样方法存在的损伤充填体现象,提出了充填体金刚石钻机取样法,并详细介绍了该方法的取样步骤及测试方法。该方法在金源矿业公司的工程应用表明:充填体金刚石钻机取样法不仅简单高效,而且基本实现了对样本无损伤取样,可在同类型矿山推广应用。
The quality of filling bodies directly decides the quality of underground mining environment.Sampling from filling bodies is necessary for quality inspection of filling body.But conventional sampling of filling bodies will cause filling body damage.So the paper proposed sampling from filling bodies with diamond drilling machine and described the steps and testing of the method.The industrial application of this method shows that sampling from filling bodies with diamond drilling machine is not only simple and efficient,but also can realize sampling without damaging the sample.The method can be promoted in similar mines.
