摘要
煤炭生产过程中,锚杆的应用十分广泛,但是在退锚时有时会比较困难,而常用的退锚方法在退锚时出现很多弊端。针对这个问题,提出将前混合磨料射流技术应用于退锚技术研究,并通过切割锚杆实验,用正交实验法确定主要几何参数对切割产生的影响,优选退锚切割参数。
Anchor bolt is widely used in coal production, but it is uneasy to unload the anchor bolt sometime while the common cutting methods have lots of inferiors. The paper proposes the application of pre mixed abrasive water jet abrasive water jet technology to the cutting of anchor bolt for this problem. According to the experiment of cutting anchor bolt, studying the selected parameters＇ cutting impact by orthogonal experiment, the cutting parameters are optimized.
