Outline
Based on the practical engineering background of separation of drilling and blasting operations in an iron mine, research was carried out on prominent problems induced by the separation of drilling and blasting operations, including difficulties in production organization and coordination, lagged inter-process information transmission, information silos in blasting operations, frequent operational risks, and high production costs. Using blasting accident case analysis and fault-tree-based risk assessment method for blasting operations, an intelligent management and control scheme for blasting operations in multiple working faces was established. Based on the Vue+Django framework, an intelligent blasting operation management and control system featuring real-time interaction, process task allocation, precise management of blasting materials, and multi-level personnel control was designed and developed. Results show that, under weak-signal conditions, the system maintains an information transmission delay of approximately 250 ms, a packet loss rate of 0.3%, and a reconnection time of less than 3 s. Under a concurrency level of 1 000 users, the system maintains an average response time of less than 1 s and a transaction success rate exceeding 98%. Following field application, the risk frequency of blasting operations is significantly reduced, considerable costs are saved, and blasting efficiency is improved, thereby effectively solving the coordination problems between drilling and blasting operations. The obtained results provide a feasible technical approach for the intelligent upgrading of mine blasting operations.
