Research on Advanced Detection Technology and Imaging Method of Mining Machine Source Based on Improved Cross-correlation Method
The development of advanced exploration technology in coal mine is great significance to the safe and efficient excavation of roadway.Based on the comparison of the source signal of the mining machine and the traditional source signal,an improved cross-correlation function processing method is proposed to transform the continuous source exploration problem into a single-shot source exploration problem.Through numerical simulation and field experimental data,the processing and research of the advanced detection data of the earthquake are completed.The results show that the improved cross-correlation function processing method can effectively pulse the source signal of the mining machine and complete the purpose of fine detection in front of the roadway to a certain extent,which has significant field feasibility and application value.
