Deep-sea mining has significantly advanced over the past decade due to the discovery of valuable minerals across 360 million square kilometers of the ocean floor, predominantly below 200 m. This research addresses the unique challenges posed by deep-sea conditions by exploring soil-plate interaction dynamics in geotechnical engineering. The study aims to optimize geotechnical structures through in-depth analysis of sinkage behavior, shear testing, and the influence of grousers on soil displacement and failure patterns. Sinkage parameters kc, kΦ, and n were derived from tests across various soil types, showing that kc increases proportionally with soil strength. Experimental shear tests on soil with 30 kPa shear strength revealed an interface angle of 30°, while numerical simulations predicted angles between 33 and 35 degrees for different soil strengths. The results indicate that increasing pitch height from 20 to 40 mm leads to higher soil accumulation without affecting slip occurrence. For a plate aspect ratio (L/B) of 2, the optimal grouser configuration includes 4 grousers, 30 mm pitch height, and 20 mm spacing, minimizing slippage while enhancing traction and stability across diverse soil strengths. This research advances the understanding of soil-plate interaction and provides insights for designing reliable of mining machine track shoe in deep-sea environments.
