Analysis on earth penetration performance of magnetic induction-based through-the-earth wireless initiation system using large circular transmitting antennas
摘要
Abstract
In order to realize large-scale through-the-earth(TTE)wireless initiation in blasting operation scenes such as open pit mines,a TTE wireless initiation system based on magnetic induction(MI)with large circular transmitting antenna coils at the ground transmitting end is studied.The equivalent circuit of transmitting antenna coils and receiving antenna coils in MI TTE wireless initiation system is established.Based on the equivalent circuit,the MI intensity model of TTE wireless initiation with large circular antennas at the transmitting end is established,and the MI intensity threshold of TTE wireless initiation is calculated.The influence of penetration depth,turns and radius of transmitting antennas and transmitting power on TTE MI intensity is simulated and analyzed.The results show that the TTE wireless initiation system can detonate the detonators at the depth of 7.52 m underground,and the initiation depth of the TTE wireless initiation system can be improved by increasing the number of turns of the transmitting coils,appropriately reducing the radius of the transmitting coils and increasing the transmitting power.The research conclusions provide a theoretical basis for the parameter selection of the MI TTE wireless initiation system based on the large circular transmitting antenna coils.关键词
