| Abstract: | When the strength of the rock in the raodway is greater than 100 MPa above,it is very difficult to drive.The application of EBZ-300 digging machine using in water warehouse roadway in Huipodi mine was introduced.And the properties,the application process,use efficiency,the existing problems and benefit of digging machine were analyzed.Field application showed that the digging technology with EBZ-300 machine could increased 71% driving speed than the blasting driving,and the average driving speed in water storehouse reached 85 m a month.The driving efficiency was greatly improved and the driving cost reduced,which provided important reference value for fast driving in hard rock roadway. |
