| Abstract: | Using ANSYS/LS-DANA program,a numerical simulation of the steep crack extending area of sandstone water-bearing zone under the action of blasting with cylindric water-coupled charge in large-diameter super-deep hole is carried out, The technique of blasting grouting forward is put for the reinforcement of surrounding rock and used in the air pit of Liuzhuang Mine of Huainan Xinji Diggings,some good effects are gained. |
