Drilling apparatus described in any one is crept into, and is specifically comprised the following steps:
Step 1: selected polar glacier target exploration region, obtains target exploration areal geology data, according to the geologic information
Pre-drilled cavity depth and drilling depth are preset, determines drilling well embodiment, pre-drilled cavity is completed and positions work；
Step 2: drilling machine is in place, start main winch, transfers ultrasonic heat rhinestone head；
Step 3: carrying out pre-drilled cavity drilling operation in ice and snow layer:
Start the first driving power, the ultrasonic frequency electric signal of the first driving power output is sent to the first pressure through armored cable

Step 7: the mixing water extraction in drilling is delivered to water tank via return pipe by immersible pump, then conveyed by suction pump
To heater, as the hot water raw material for continuing drilling；
Step 8: closing valve and the first driving power after drilling predetermined depth, control electric winch system withdraws ultrasonic heat
Rhinestone head and immersible pump；
Step 9: when tension sensor data show exception, closing valve during round trip, stopping ultrasonic heat water drilling
The supply of head hot water, starts the second driving power, and the ultrasonic frequency electric signal of the second driving power output is passed through armored cable
The second piezoelectric ceramics is passed, the ultrasonic frequency electric signal received is converted into mechanical oscillation and become through second by the second piezoelectric ceramics
The amplification of width bar, makes the ice-out positioned at ultrasonic heat rhinestone head top, while starting main winch pull-up ultrasonic heat rhinestone head, into
Row unfreezing closes the second driving power and recycles ultrasonic heat rhinestone head after unfreezing.
