METHOD TO CONSTRUCT MINES AND PITS AT NONTERRESTRIAL OBJECTS Russian patent published in 2011 - IPC E21C51/00 E21D1/00 

FIELD: mining.

SUBSTANCE: method includes erection of the main and auxiliary shafts with a drilling rig from a shelter building, installation of sealing and heat-insulating ramps in shaft collars. One of the auxiliary shafts is erected in the form of a microscope, drilled from an exploratory well by means of its expansion from an inner mine tunnel until reaching the surface of an nonterrestrial object and used as a saving shaft, which on the surface via a gate chamber contacts with a landing complex of a spacecraft. In the saving shaft in the area of its connection with the inner mine tunnel there is a sealing heat-insulation ramp installed, drilled solids are distributed into a crater of the nonterrestrial object.

EFFECT: invention makes it possible to carry out salvage operations and to ensure the necessary ventilation in mines and pits, and also to establish a connection between the shafts on the nonterrestrial object surface.
