| Abstract: | 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. |
