The present application relates to polar ice layer drilling technology field, disclose a kind of double-layer cutting hot melt chip removal large-diameter ice core coring drill. The drill includes cable suspension and electronic component system, melt chip pump suction system, anti-torque and driving system and coring system arranged coaxially in sequence;Melt chip pump suction system includes water tank, water suction pump, water suction pipe and melt chip resistance wire, melt chip resistance wire is arranged around the outside of drill bit body in coring system, melt chip resistance wire is electrified and heated during drilling, for cutting the solid ice chip generated in real time hot melt into liquid melt water, water suction pump is used to pump melt water at the bottom of borehole to the inside of water tank for storage by water suction pipe.The present application eliminates the sticking accident caused by the fact that the ice chip is not removed cleanly when obtaining large-diameter ice core from the root, reduces the space occupied by melting the ice chip into water, has the advantages of compact structure, good ice core quality, high drilling efficiency, etc., and is suitable for coring operation in polar, alpine glacier and other scenes.
