| 摘要 |
The present invention relates to a bedrock cracking apparatus using an ice bomb in the shape of a powder keg and, more specifically, to a bedrock cracking apparatus using an ice bomb in the shape of a powder keg, for making a perforated hole in bedrock using a perforating apparatus and for injecting, into the perforated hole, a sealed tube having water filled therein and liquid nitrogen by using an injection apparatus so as to cause cracks in the bedrock using the principle that water expands in volume when frozen and thus to crush the bedrock more easily. The present invention is characterized by comprising: a packer fixedly inserted into the entry of a perforated hole formed in bedrock; an inner tube which is provided in the packer and has water accommodated therein; an injection apparatus connected to the packer; a nitrogen injection nozzle which is installed in the injection apparatus and passes through the packer; and a supply unit connected to the injection apparatus so as to supply liquid nitrogen. |
