Abstract This study investigates crosstalk in shearer cables used in underground environments, affecting their electromagnetic stability. Unique underground conditions necessitate specific research for these cables, unlike those for vehicle, aircraft, and railway cables. This paper uses a finite-difference time-domain (FDTD) modeling method with EMA3D to accurately simulate these conditions and explores integrating steel wire ropes within control cores to enhance electromagnetic stability.Simulation experiments show that embedding steel wire ropes significantly improves electromagnetic stability. Optimal shielding occurs when the steel wire rope diameter matches the twisted diameter of other cable cores, enhancing stability by over 20% compared to cables without steel wire ropes. Under bent conditions, larger steel wire rope diameters improve effectiveness by more than 10%. The study also examines the impact of the diameter difference between steel wire ropes and twisted cable cores, finding that a larger difference has a more significant impact.These findings suggest that the relationship between the diameters of steel wire ropes and cable cores should be carefully considered in cable design to optimize electromagnetic stability. This study provides an effective solution to crosstalk in shearer cables and offers insights for improving electromagnetic stability in various applications.
