摘要
通过分析传统退锚中出现的弊端,提出了将前混合磨料射流技术应用于切割锚杆锚索。试验证明,该技术不仅满足矿井下的安全生产要求,而且切割的效果好、效率高,可节约大量人力及时间。
After analyzing the shortcomings of traditional bolt unloading operation, the paper proposed to apply pre-mixed abrasive water jet technology to the cutting of the bolt cable. The test showed that the technology could meet the requirements of safe production in underground mines with good cutting effects and high efficiency, thus labor and time decreased greatly.
