The high-quality development of engineering blasting lies in promoting the application research with refinement, innovation of process, equipment and apparatus.Aiming at the demand of precision blasting, the theoretical research process control, safety management and intelligent construction should be deepened.Precision represents the times characteristics of science and technology, and it is a reflection of cognition and practice.Meanwhile, Precision includes all aspects.However, its core should reflect the overall planning of precision and process control.The overall planning of precision should highlight the combination of demand and process control of length, capacity and weight etc.The process control should focus on the rationality of the fineness of the key links.In this paper, the concept of precision and fineness is expounded that precision based on overall accuracy is the key to scientific digitization and intelligentization, so as to realize the specialization, time-domain and systematization of data in a fast, good and economical way, and lay the application logic foundation for data manage data management.Based on overall planning of key processes, refinement is to establish a reasonable matching control logic of people, materials and things.Furthermore, with a complete process means of loop connection and closed-loop control, process elements would be accumulated for intelligentization.Precision, digitalization and intelligentization connects the past with the future, mutual cause and effect, unity of opposites.
