PROCEDURE FOR SOIL EXPOSURE AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2011 - IPC B65G5/00 F42B3/00 

FIELD: gas-and-oil producing industry.

SUBSTANCE: invention refers to oil, gas and mining industry and can be implemented for expedient remote exposure of dormant or spent mines used as storages closed with soil, and for oil, gas and hydro-geological boreholes. The procedure for soil exposure consists in placement of a casing in form of a truncated cone or truncated pyramid with its bigger end to surface of soil over a chute of a container for a device equipped with a source of high pressure gases (HPGS). The casing is furnished with anti-adhesion coating on internal surface and is secured with its smaller end to the chute in an upper part of the container and axially - to the chute. The HPGS is positioned under the casing. Lengthwise axis of the casing and chute axis are arranged at acute angle to vertical. When the casing is filled with soil a flat easy destructed partition is mounted on the big end of the casing; the partition is made in form of a circle with diametre bigger, than diametre of the bigger end of the casing. The partition is covered with anti-adhesion coating at least on one of its surfaces. Soil is placed on the partition, thus forming a masking layer over the casing, and the HPGS is actuated.

EFFECT: reduced material input to structure of container and increased reliability of soil exposure.
