Purpose of the development: A method for controlling the active heave soil unloading and subsequent strengthening ARPU rocks intended to eliminate frost heave workings when drifting or exploitation.

Recommended application field: In the capital and preparatory mountain developments for various purposes instead invert mounting and blasting of rocks soil, where it is expected intense heaving rocks.

Advantages over analogues: ARPU method allows to: - increase the stability of production as a whole and prevent frost heave; - reduce complexity, improve performance of work compared to conventional invert more than 3-4 times; - eliminate the cost of metal, concrete, increase the penetration rate in the rocks, puig, 1.5-2 times.

The development stage readiness: Ready for application

Technical and economic effect: Economic efficiency is 1.5-2 bln. UAH in year.

Description of the development:
()
A method of controlling soil heaving active unloading and subsequent strengthening ARPU rocks intended to eliminate frost heave workings when drifting or exploitation. He is an active intervention in the processes of destruction and displacement of rocks around a mine working. Unloading the soil from rocks voltage explosion kamufletnyh explosive charges, creating an explosion loosened rock zones and, finally, the further strengthening of exploded rocks bonding solution, creating the soil produce powerful porodobetonnoe reverse mixing high load-bearing capacity. ARPU ways technology is based on an active management method stressed state and strength of rocks.

Possibility of transfer abroad:
Combinated reduction to industrial level
