- Abstract
Aiming at the problems of low precision of rock drilling, poor traditional blasting effect and high accident rate for traditional blasting operations, combined with the characteristics of mine blasting operations, the concept of 3P (Precise, Punctilious and Perfect) blasting is introduced into mine blasting. This paper first briefly introduced the definition and development status of 3P blasting, and then discussed it from three aspects: refined design, refined construction, and refined management, followed by the application situation was further elaborated, combined with 3P blasting technology in Heiyugou open pit mine and Shandong Tangkou coal mine. The results indicated that compared with traditional blasting, the use of 3P blasting technology has obvious advantages in construction efficiency, blasting effect, safety and environmental protection. Finally, a brief introduction to the development of China's future 3P fine blasting technology was given.
