| description | To analyze the influence of radial decoupling parameters on the blasting effect of limestone, finite element analysis was established using ANSYS/ls-dyna to analyze the effects of different radial decoupling coefficients and different media on blasting. Research has found that limestone has more cracks and more pronounced cracking when air is uncoupled. Under the condition of air decoupling, the stress waves in the rock mass are more concentrated and have higher energy, while under the condition of water decoupling, the stress waves in the rock mass diffuse faster, have a larger range of action, and have lower energy. Reasonably increasing the radial decoupling coefficient can effectively reduce damage around the borehole. For limestone formations, it is recommended to use an air decoupling method during construction, with a radial decoupling coefficient kd=2.0 for the borehole. |
