Description

(5) DEVICE FOR DELIVERY OF EXPLOSIVE SUBSTANCES TO DIFFICULT ACCESS

one

The invention relates to drilling and blasting operations and can be used, in particular, in the open-pit mining of mineral resources under permafrost conditions.

When charging chamber charges with a packaged explosive (BB), the explosives and gunmen are delivered by trolleys ll.

A significant drawback is the need to form large cavities for trolleys (up to 2.5 x 1.5 m), and for staff it is necessary to create fastenings in cavities, lighting and ventilation.

In order to deliver a charging hose for mechanized well charging of loose explosives, a known trolley (hose trolley) has separate coils for hoses laid along the workings and an integral sliding coil for the charging tube that enters the well in the case of charging with deep explosives. wells 2.

This device is also not foreseen; looks at the militant's delivery to the face, and the cart with the hoses is moved by hand making. In addition, the dimensions of the trolley are such that its movement in the workings passed by the pressure jet of water, having an uneven cross-section along the length, is difficult and explosive.

The purpose of the invention is to increase the safety of delivery of explosives and reduce the charging time.

Claims (2)

The goal is achieved in that the device is equipped with a reel for a detonating cord, and the action mechanism’s feed mechanism is made in the form of a container with an opening bottom and wheels, and one of the container walls is equipped with a spring-loaded figured probe installed with one end of contact with the bottom wall, and the other with bottom of the container. In addition, the bobbin axis is eccentric. The presence of the container prevents the militant from contacting the working soil during transportation and damage to the detonating cord, and by making the reel with an eccentric axis located, the detonating cord does not twist and does not bend during operation. FIG. 1 shows the device, a general view; FIG. 2 shows a section A – D in FIG. The device consists of the expandable injection pipe 1 placed on the container 2 with the opening bottom 3. The container consists of a rectangular container reinforced inside with a rubber gasket. The dimensions of the container depend on the size of the thug placed in it and reach 0-0 03-0 , 5 m. In the container wall k facing towards the bottomhole, an opening 5 is made for a container, the free end of a detonating cord 6 wound on a reel 7, is drawn into the cavity. The axis 8 of the reel 7 is placed eccentrically in slots 9 and guides 10. Ecce Attaching the bobbin axle to tension creates the required tension of the detonating cord, which ensures safety during operation. A shaped probe 12 is attached to the wall A of the container by means of a spring 11, one end 13 (sharp) of which interacts with the wall of the working and the other 1 - with the container 3 that opens with the bottom 3. The pressure pipe 1 is placed on container 2. The reel 7 and probe 12 are covered by a casing 15. The device is placed on coast 1b. The device works as follows. Pre-produced prep. device to work. For this, the fighter 17 and the free end of the detonating cord 6 are placed in the container 2. The length of the cord placed in the container should not be less than the working section of the mouth of the explosive mixture coming out of the pipeline 1. The specified cord line ensures that it is laid on the working soil required location. 64 When the device is ready for operation, it is connected to the pneumatic feeder 18, installed in the wellhead. and then moved to the bottom. When a hole is reached, the end 13 (sharp) of probe 12 rests on the bottom face. The resulting force compresses the spring 11, the probe 12 moves, and the protrusion 1 of the probe releases the bottom 3 — it opens, the fighter drops out of the container under its own weight and rests on the bottom of the excavation in the required place. After laying the action movie, pipeline 1 from the pneumatic feeder 18 serves explosives. The device is then rolled back to a distance equal to the length of the stock of the detonating cord, which lies on the soil of the mine outside the zone of action of the explosive jet, and again an explosive is supplied through line 1. The process is repeated until the generation is filled with a given amount of explosives. After charging is complete, the device is removed from the mine. The presence of the container makes it possible to completely isolate the thriller during transportation and deliver it to hard-to-reach cavities, and since the detonating cord is placed in the container, it thereby excludes its damage. In addition, due to the eccentrically located axis of the reel, the required tension of the detonating cord is provided, and it is laid on the soil of development without twisting and bending, which eliminates the possibility of detonation breakage and, consequently, failure. Placing the container on vehicles and the presence of a stackable pipeline ensures the safe delivery of the fighter into hard-to-reach cavities. Apparatus of the Invention A device for delivering explosives to hard-to-reach cavities, including a pneumatic sensor connected to an injection pipe and a feed mechanism for the fighter, characterized in that, in order to increase the safety of the delivery of an explosive and to save charging time, the device has a reel for detonating , and the action mechanism of the action movie is made in the form of a container with an opening bottom and wheels, with one of the container walls provided with a spring-loaded figured probe mounted with the possibility of contacting one end with the bottom wall, and the other with the bottom of the container. I 2. The device in accordance with claim 1, 1, and 2 tons, and that the axis of the reel is eccentric. 881 5 16 Sources of information taken into account during the examination 1.Avdeev F.A. et al.
