The temperature distribution of the rock surface was numerically analyzed after the rock was irradiated by laser,and near-infrared high power laser perforation of rock was experimentally studied under condition of different rock types,rock size,laser power,irradiation time and other factors.The experimental results indicate that the different types of rocks have different perforation effects due to its different components.When boundary effects are eliminated,rock size has no effect on perforation efficiency.For the same type of rock,there is a specific laser power during drilling,and it can make the rock perforation has the highest efficiency.The efficiency of laser perforation decreases with the increase of laser perforation irradiation time.Meanwhile,the environment will affect the rock laser perforation efficiency.
