Description

Изобретение относитс к горной промыц анности и может быть использовано дл бурени шпуров и скважин.The invention relates to the mining industry and can be used for drilling holes and wells.

Известны устройства дл термического бурени горных пород, включающие кольце- 5 вую и центральную горелки, систему коммуникаций дл подачи топлива и окислител .Devices for thermal drilling of rocks are known, including an annular and central burner, a communications system for the supply of fuel and an oxidizer.

В предлагаемом устройстве в центральгной горелке размещен сердечник с форсунками , внутренн полость которого сообщена ю с магистралью дл подачи твердых веществ. Это позвол ет повысить эффективность буровых работ.In the proposed device, a core with nozzles is placed in the central burner, the internal cavity of which is connected to the main line for supplying solids. This makes drilling more efficient.

Claims

The fuel components are supplied to the common distribution head 4 and further along the channels to the swirler nut 11 with nozzles 12n removable distribution head 7 with the odor; a sunflower system 8. Each component has an individual flow control. Through the f () drywall systems 12 and 8, the componeites are introduced into the annular and central combustion chambers, respectively, where they mix and burn to form an annular and internal central drill of the sound high temperature thermal gas flows. Water for cooling is supplied via a supply line to the channel around the distribution head 4, and then into one of the two helical grooves in the central combustion chamber 9. Having cooled it, water from the nozzle section of the chamber along the second screw groove turns into another channel of the common distribution head 4 and enters the cavity of the extension rod 6. From here, through the system of holes j in the common distribution head 4, water flows into the cavity between the outer casing 2 and the annular chamber 3 combustion cools it and through the holes in the calibrator 1 is thrown out to enter into the annular torch of solids or explosive mixtures containing solids, a flow channel is necessary to ensure unhindered they are transported from the feeding devices to the flare outlet. Such a kignal is formed by replacing G with a removable detection head 7 with a core 13. The central combustion chamber 9 and the housing 1O in this case only need core cooling of the core 1 solids along a straight central line under the action of their own amp or air are transported to through hole 5 in common distribution head 4 and fall into the internal cavity of the core 13, Fluxes, metallizers and ready-made explosives, such as granulites, pass through the core and are inserted into the torch of the annular burner. explosive mixtures of non-explosive components, such as ammonium nitrate and kerosene, the latter through the nozzles 15 in a spray form in the required amount is introduced into the core, where it mixes with the nitrate and forms an explosive mixture (igdanite). blast mix. The initiators of the explosion are heat and shock impulses. Increase pressure; In the annular flare, the explosive mixture interrupts (the central burner locks in), which is reopened only after the pressure drop, the device then operates in a pulsating mode. The frequency and power of the pulses is controlled by the second consumption of KOMnoHeeits. The cooling of the device is carried out in the same way as with a central burner. The invention The device dp thermal drilling of rocks, including annular and central burners, the communication system dp fuel supply and oxidant, about tl including that, in order to improve the efficiency of drilling, in the central burner is placed a core with hole, the internal cavity of which is connected to the main line for feeding solid substances.
