摘要
从高压水射流的理论基础和煤岩的失效机理 2个方面 ,对高压水射流扩孔的机理进行了研究。介绍了高压水射流扩孔技术的装备和工艺。对研究开发的高压水射流扩孔技术和装备进行了现场试验研究 ,取得了好的效果。
The paper has a research on the bore hole enlarging mechanism with high water jet based on the theoretical foundation of high water jet and the failure mechanism of coal and rock. The paper detailedly introduced the equipment and technique of the bore hole high water jet enlarging technology. The technology and equipment of the bore hole enlarging with high water jet had a site test and research with excellent results. The bore hole enlarging technology with high water jet is a new economic feasible technology to improve bore hole drilling and gas drainage results.
