FIELD: mining; construction.
SUBSTANCE: method of horizontal radial drain hole constructing in hard rocks includes vertical shaft sinking and drilling from it horizontal radial drain hole and constructing from its bottom additional vertical shaft. Using both shafts along the full length of horizontal radial drain hole it is located string camouflet charge. After charge explosion there are formed horizontal radial drain hole with area of bund fracturing and then on one side of newly formed horizontal radial drain hole there is mounted surface casing with closer and draining, and on the other - choke. On drained territory there is installed at least one hydro-supervisory well.
EFFECT: reduction of drill footage; reducing of horizontal radial drain hole breakingin terms; rising of its interception ability and ability to make an attendance for dewatering drained territory.
