Abstract
In order to clarify the adaptability of the application of shaped charge blasting technology in the roof cutting and pressure relief of deep buried thin bedrock mines,the key technical parameters of shaped charge blasting are designed,and the construction process and hole sealing process of shaped charge blasting are optimized based on the research background of the 16061 upper channel of Zhaogu No.1 Mine.The research results indicate that using a mining hole sealing device combined with a grouting pump to complete the hole sealing can effectively improve the efficiency of powder charging and hole sealing,and the pre-splitting blasting joint-cutting effect of blasting hole parameters is good,which can meet the current requirements for roof cutting and pressure relief.关键词
