The control of blasting rockfall is the crucial guarantee for safety production in the blasting process of mining exploitation.A comprehensive method of theoretical analysis and model research is used to study the control of blasting rockfall in Changjiu Shenshan Limestone Mine.The mechanism of rockfall in the blasting process is summarized.A simplified kinematic model is established,and the distance of rock movement is calculated and the influence range is predicted.The results show that without any control measures,the maximum movement distance of the rockfall can reach more than 150m,and the influence scope covers the surrounding houses,fields and highways.According to the engineering practices and production demands of Changjiu Shenshan Limestone Mine,millisecond loose blasting method with preserved dike,holding rockfall net and ditch safety system are proposed from the source and the process respectively to control the hazards of blasting rockfall movement.In the meantime,measures relocating out of precautionary areas within 300m of the mine right line are taken.The technology provides reference for rockfall protection engineering and blasting projects in other complex environments.
