Abstract
Способ возведения искусственных тумбообразных целиков в россыпных шахтах криолитозоны, включающий укладку в зимний период промороженной щебенисто-галечной смеси, подаваемой с поверхности через специально пробуренную скважину в предварительно сооруженную под землей опалубку, отличающийся тем, что уложенную в опалубку щебенисто-галечную смесь уплотняют, а затем разогревают и увлажняют перегретым паром, подаваемым в количестве не менее 10 м3 на 1 м3 смеси, промораживают атмосферным воздухом. A method of erecting artificial pillar-like pillars in alluvial mines of the permafrost zone, including laying in winter a frozen frozen gravel-pebble mixture supplied from the surface through a specially drilled well into a formwork previously built underground, characterized in that the gravel-pebble mixture laid in the formwork is compacted, and then they are heated and moistened with superheated steam, supplied in an amount of at least 10 m3 per 1 m3 of the mixture, frozen with atmospheric air.
