Description

When blasting for the use of minerals is applied, the work process is characterized by the following stages of the work itself: first the drillers drill holes, then all the tools are cleaned and people are removed from the mining faces, after which the burrs fill the holes and make holes. Cleaning works are resumed only after a certain amount of time is needed to air the workings.

When using the proposed boring machine, it is possible to make a breaker without removing the machine from the bottom and not removing the drill or drill from the hole by welding out Cardx-type cartridges connected directly to the hollow drill or drill, and all the work is done by one driver.

In FIG. 1 depicts a boring machine; FIG. 2 and 3 - application of the boring machine to the machine for the extraction of minerals using wedges.

The technological process that the proposed machine produces is reduced to the following: auger 3 (Fig. 1) using the cutting crown J8, using the rotary or

percussion, enters the massif of the fossil to the desired depth, and then into the hole, in which the drill 3 of its part B is located, along the internal ridge of the drill. "Through the holes visible in the drawing, it is blown out at tremendous speed under the pressure of hundreds or thousand - either in the form of gas or steam. The pressure that is created in this manner in the hole, along with the speed of its formation, resembling the effect of an explosion, destroys the fossil. The source of high-pressure matter can be a steel cylinder 7 filled with liquid carbon dioxide, water, etc. The cylinder outlet is closed with a steel washer 8 pressed with a nip pel 9. Inside the cylinder 7, a holder 6 is strengthened by a thermite rod that can be burned with electric current, The nipple 5, which is fed through the insulated from the housing 7, is known from the positions 5, 6, 7, 8, and 9: in the technique of coal mining, called Cardox. Including the current in the nipple 5, they burn the termite, reinforced in the holder b, which turns that substance into which the balloon is filled into a hectare or vapor. With a pressure of about 2000-3000 atmospheres, the washer 8 is cut off and the gas along the drill cavity is eliminated into the hole, destroying the fossil. The cylinder is attached to S expansion A of the drill 3, which can be done, as shown in the drawing, up to the drive mechanism /, 2, and behind the drive mechanism /, 2 for ease of changing the cartridges 5, 6, 8 v. (9. Cartridge it can be filled with water and warmed up with electricity without termite, which makes this machine very: growth, cheap and simply serviced,

The drill-boring machine can be installed on the proposed combined machine (Fig. 2 and 3), then “along the blade along the side like iron cutting machines. One or more hollow rods 77 drill coal with a crown / using one or another drive design / 5. When the rods / 7 are smashed into coal to failure, the Cardox / 7 cartridges are fused out, after which the destroyed coal does not prevent further mixing of the machine, which with its blade / 5 and wedge 72 removes the coal from the bottom and, if necessary, - the apron 75 loads it on the conveyor.

Blade 75 with wedge 72 can be moved apart, adapting to the formation with mechanical or hydraulic devices} 4.

Devices with the help of which both a strictly straight-line movement of the machine along the bottom and a maneuvering of it, can be achieved, can be applied, either hydraulic, as shown in the drawing, or mechanical. The machine can be fixed motionlessly with one or another structure by the supports 7, which can be used as a fixed support of cylinders - a tool for which the machine can move across or rotate. An electric or pneumatic or some other engine 7 drives pumps or compressors located in the crankcase 9, feeding the device for moving the fasteners and maneuvers. The machine under consideration will be indispensable for the development of those fossils and coals that are poorly or not at all amenable to npza, cutting preparation with a notch or cutting.

It is irreplaceable also where the notch greatly lowers the grade of coal or mineral. The ability to implement it very low makes it indispensable for very thin reservoirs, the development of which still could not be profitable. It can also be used for top-down excavation, which is extremely important for steeply dipping seams.

The subject matter of the invention.
