Abstract: For development of large equipment，such as drill jumbos，digitalization and intelligence are the trends in future. In order to clarify the research direction of the self-developed drill jumbo，combined with the current status of the drill jumbos applied in China's underground mine，where the drilling and blasting method is used，the technical advantages and problems of drilling accuracy，drilling efficiency，safety of personnel and environmental protection indexes of the drilling platform used on site are quantitatively evaluated.Investigations results show that using drill jumbo，the drilling time for a single hole is 2~3 minutes，which drilling efficiency is 2~4 times of the one by pneumatic rock drill under the same conditions； with reasonable blasting methods，it can increase the advance per month by 50%~70%. When using the drill jumbos on-site，some problems are often existed，such as the mechanical performance do not match the drilling and blasting process， the actual over-excavation is often larger than that of pneumatic drilling，and the personnel training is fall behind its real needs.Besides that，the intelligent development progress of drill jumbos at this stage is summarized.The Research shows that through compensation，the average positioning accuracy of some cases is below 5 cm，which can meet the requirements of construction；with the help of advanced technologies such as visual aided positioning and navigation methods，5G technology and the internet of things technology，it can achieve the goal of fewer people and unmanned operations. At last，the insufficient and challenges about develop and promote the self-developed drill jumbos in future is analyzed，and the development route of self-developed drill jumbo is summarized and prospected.
