矿山深孔钻探绳索取芯钻进技术的应用研究

Research on Application of Wire Coring Technology in Mine Deep Hole Drilling

众所周知,对于矿山开采将要面临的困难数不胜数,岩石、细砂等复杂地貌多见。随着矿山开采历史的发展,开采技术也在不断革新。新型工艺层出不穷,本文介绍的这种深孔钻探绳索取芯钻进技术,与往日使用开矿用的金刚石钻具不同,它属于液动冲击回转钻具,无论在工作效率还是精准度方面都比老式金刚钻式工具有明显提高,是一种现实可行的高效、优质且低消耗率的钻进工艺,此种技术的发展对于日后的矿山开采工程的顺利进行具有重要意义。

As we all know, there are numerous difficulties in mining, and complex landforms such as rocks and fine sand are common. With the development of mining history, mining technology is also constantly innovating. New technology emerges endlessly. The wire-line coring drilling technology introduced in this paper is different from diamond drilling tools used in mining. It belongs to hydraulic percussion rotary drilling tool. It has obvious improvement in working efficiency and accuracy compared with the old diamond drilling tool. It is a practical, high-efficiency, high-quality and low-consumption drilling technology. The development is of great significance to the smooth development of mining engineering in the future.
