Abstract: An advanced BZXJ drill was developed and named after key Chinese characters which mean an electro-mechanical ice core drill. Its main advantages are: light weight, low power consumption and convenient installation. The drill has the merits of both an electro-mechanical Japanese ice core drill and an American SIPRE/CRREL 3 inch auger. Its major characteristics are: 160cm length, 11kg of weight, about 50 rpm core barrel rotation speed, about 35cm length core section extracted during one run, 0.3kW power consumption, 150m depth capabilities. The total weight of drilling system is 127kg. The drill can be set up and operated by two specialists. A few glaciers have been drilled to bedrock in China by BZXJ. Also about 700m total length of ice core have been obtained from the Collins Ice Cap, King George Island, Antarctica. Where the maximum depth of 80m borehole have been drilled. It was shown on high mountain glaciers that the BZXJ is suitable for firn and ice coring.
