STARTING DRILLING SITE FOR DIRECTED DRILLING AND PREPARATION OF ROCKS, MINERAL PRODUCT FOR REMOVAL Russian patent published in 2011 - IPC E21B3/00 E21B7/00 

FIELD: mining.

SUBSTANCE: starting drilling site includes anchor post with device of attachment and turn at any angle to horizon with special guide with stay, monoblock supply assembly of drilling rods with slots connected to holes of spindle, which is brought into rotation from reduction gear with electric motor or hydraulic motor, distributor with oil station, vacuum pump, capacity for collection of sludge with gas outlet branch pipes, and structure for remote control and automatic rod addition. Special guide on end part is tubular and has holes for spacer assemblies (stay) and has spring-loaded shell with flexible edges, which contacts the surface around the well with exceedance of diameter by not less than two times. Middle part of the guide has semicylindrical section, longitudinally moved assembly connected to it and spindle arranged in it with circular slots (oval) matched with their holes and holes on longitudinally moved assembly with reduction gear with electric motor or hydraulic motor, which is fixed on it. Additional fixed semicylindrical section is provided with channel for collection of large fractions, core to the capacity. Spindle for output of small fractions, sludge, fluid and gas has reduced central hole with outlet towards the hose, which is connected to end movable special guide and capacity for collection of these destruction products, which has a partition with bypass holes of small fractions, fluid, sludge from collection capacity of large fractions, core. Channel is not provided in fixed part of special guide, and spindle is equipped with central hole equal to diameter of core protruding from drilling rod.

EFFECT: enlarging functional capabilities and application area.
