Taking the existing excavation and cutting technology of Gucheng Coal Mine as an example,a design scheme of improved technology for rapid excavation of coal roadways was introduced.Various excavation and cutting schemes were designed based on the specific situation of the original excavation and cutting technology and combined with the level of excavation technology in the coal mine field.Then,finite element analysis software was used to simulate and analyze the application effects of each scheme in practice.By comparing the simulation analysis results,the final excavation and cutting scheme was determined.The application of the improved technology can not only improve the excavation speed of coal roadways,but also improve the safety of underground operations.It is confirmed that the improved technology is of certain application value.
