Abstract: Intelligent blasting is an important direction for the transformation and upgrading of the blasting industry. However,the traditional wired network blasting with manual operation is complex and has a low level of intelligence,which seriously restricts the efficiency of on-site blasting operations. Therefore,developing a reliable and applicable intelligent wireless blasting equipment is of great significance. By comprehensively adopting modern widely used information communication technologies and combining them with open-pit mine blasting construction,an intelligent wireless blasting module,an intelligent blasting controller,and a relay device carried by unmanned aircraft have been developed to achieve two-way wireless communication, ensuring normal communication and reliable blasting in the complex electromagnetic environment of the blasting operation site, and solving the problems of the limitation of the number of electronic detonators that can be detonated by a single blasting machine at one time and the restricted setting of the blasting station location in complex geographical environments. The field test in the Dapai Project in Zhaoqing City,Guangdong Province shows that the experimental effect of adopting the intelligent wireless blasting mode in multiple bench blasting scenarios is good. The research results can help expand the scale of blasting operations,reduce the labor intensity of blasting operation personnel,significantly improve the operation efficiency, and provide strong support for the high-quality development of intelligent mines.
