Abstract
According to the Livingston blasting funnel theory, a series of single-hole blasting funnel tests were performed at the May Fourth Square Station. The relationship curve between blasting funnel volume and drug embedding depth was plotted, and the variation curves of blasting funnel depth, vibration speed and noise with burial depth were obtained. The MATLAB software was used to perform four-term regression on the test data, and the parameters such as the optimal burial depth, critical burial depth, and optimal explosive consumption of the blasting funnel were calculated.
