[0027] Specifically, based on historical data, a set of cutting decision rules is constructed for different geological conditions: In stable coal seam areas: maintain the conventional cutting path, prioritizing efficiency; For coal seams containing interbedded gangue: prioritize paths with lower hardness to avoid directly cutting through the gangue; Fault impact zone: Plan detour routes to ensure the integrity of the top and bottom slabs; Coal seam uplift / downlift zone: Adjust drum height according to boundary line fluctuations; The weights of various decision rules are dynamically adjusted based on the GCI index value in the coal seam characteristic model.
