[Abstract]:Fine blasting, guided by the theory of sustainable development, scientific development and low-carbon economy, is an important application and embodiment in the field of engineering blasting, in order to realize safety and reliability and advanced technology.Green environmental protection and reasonable blasting operation is the goal.The existing technical and equipment conditions of Bayan Obo West Mine have provided necessary conditions for the implementation of fine blasting technology. The concept of "fine blasting" is used to guide the daily production blasting of the mine and give play to the advantages of the existing technology and equipment.To accelerate the digitization and information construction of mine engineering blasting, to improve the efficiency of mine blasting, to improve the blasting effect and to reduce the blasting harm.In this paper, the practical application of fine blasting in Baiyunebo West Mine is systematically discussed in combination with the actual engineering geological conditions and technical equipment conditions, and the fine blasting system suitable for the west mine is established and perfected with the analysis and verification of the field production test data.The geological data of West Bayan Obo Mine and the system analysis of the existing mining, loading and transportation equipment are investigated. All the conditions of the mine have reached the technical conditions of implementing fine blasting, and the technical system of fine blasting in the west mine has been constructed.Further excavating the potential of the technical equipment in the west mine, such as accurately reflecting the location of the equipment and the production facilities by means of positioning, making the computer aided design system and the mining equipment organically combined.To improve the rate of information exchange in mine production, to strengthen dynamic supervision, to realize visual scheduling of production, and to improve the overall efficiency of blasting work.The radial basis function neural network (RBF) is used to analyze the blasting data, to set up a feasible and accurate blasting effect prediction model, to optimize the blasting design scheme and blasting parameters, and to improve the blasting design efficiency.The mine digitization construction of Bayan Obo West Mine is perfected step by step, the 3D model of blasting area is established by using Surpac software, and the 3D visual blasting design is carried out, the blasting scheme is displayed vividly, and the blasting result is estimated.The workload of blasting designers is reduced and the blasting design progress is accelerated.Based on the analysis of bench blasting process in Bayan Obo West Coal Mine, some suggestions for the management of blasting work flow, refinement, coordination and economy are given, which provide a reference for improving the level of blasting management in enterprises.Based on the field data of blasting vibration, BP neural network prediction model based on MATLAB is constructed to accurately predict blasting vibration and reduce the harm of blasting vibration to engineering equipment, building and rock slope.The causes of blasting flying stone are analyzed, and the measures to reduce blasting vibration and control the occurrence of flying stone are given.
