Abstract

A method for liquidation of ammunition and explosive substances in which ammunition and explosive substances are blown up at depth not less than 10-15 meters in well with large diameter cased with metal pipe, with filling space between pipe and surrounding rocks with viscous polymer substance under pressure. Preliminarily one performs backfill of massif round well to its depth with plastic polymer substance under pressure through wells with smalldiameter and in the upper part of explosive well one installs system for supply of chemical reagents. Over the mouth of the well one installs splitter of explosive gases flow to at least three directions to installed symmetrically in horizontal plane pipelines connected through valve gaps to vesselsaccumulating pneumatic energy of explosive gases. Ammunition is supplied to well by means of conveyor to which those come from rail or wheel platform by means of automated pusher controlled with end indicators of position of platform.

Description

Description of the invention

The useful model refers to the methods of destruction of ammunition and explosive substances and can be used 2 in the elimination of ammunition and explosive substances dangerous for transportation with the utilization of the energy of explosive materials and scrap metal.

There is a known method of destroying the hulls (1), which includes placing explosives in a given place and detonating them with the help of cumulative ammunition.

The disadvantage of the method is the danger of ammunition destruction work and the low productivity of these works, which 70 involves the detonation of each ammunition separately.

There is a known method of reducing the seismic effect during blasting in quarries |2), which includes drilling loosening wells, charging them with an explosive substance and then detonating it.

The disadvantage of this method is its low manufacturability in relation to the destruction of ammunition and explosives, since only one-time use of the well is possible, as well as the impossibility of energy utilization 12 of explosive materials and scrap metal.

The proposed useful model is based on the task of creating a method of eliminating ammunition and explosives, in which, due to the proposed technology, ammunition is detonated at a depth of at least 10-15 m in a well of a large diameter with a metal casing pipe and preliminary fixing of the massif surrounding the well with plastic polymers and a pneumatic connection the tongue of the explosive well with containers that accumulate the pneumatic energy of explosive gases, a useful result is achieved - the safety of the process of liquidation of ammunition and explosive substances and the possibility of utilizing the energy of explosive gases and metal scrap of ammunition.

The goal is achieved by the fact that in the method of eliminating ammunition and explosives, which includes detonating explosives in a well, according to a useful model, ammunition and explosives are detonated at a depth of at least 10-15 meters in a large-diameter well lined with a metal pipe, 22 with the filling of the space between the pipe and the surrounding rocks with a viscous polymeric substance under pressure, - in advance, the array around the well is tamped to its depth with a plastic polymeric substance under pressure through small-diameter wells, and in the upper part of the explosive well, a system for supplying chemical reagents is installed, and above at the mouth of the well, a flow breaker for explosive gases is installed in at least three directions in pipelines symmetrically located in the horizontal plane, connected through valves with containers that accumulate the pneumatic energy of explosive gases, while the ammunition is fed into the well by means of a conveyor, on which they arrive и from a rail or wheeled platform using an automated pusher controlled by end position sensors of the platform. M

The scheme of the implementation of the method is shown in Fig. 1 in a vertical cross-section along the axis of the blast well, in Fig. 2- (|Z in the top view (in plan) of the complex of ground systems that ensure the implementation of the method. 3o The method is implemented in this way.

From the earth's surface to a depth of 10-15 meters, 1 well is drilled with a large diameter - about one meter, which is lined with a metal pipe with filling of the annular space under pressure with a plastic polymer substance that connects the casing pipe with the surrounding rocks. Around this well, to its depth, the massif is tamponed through small diameter wells 2 with a plastic polymer substance, which creates an area 3 saturated with 70 polymer, which excludes the penetration of environmentally harmful explosion products into aquifers. c A conveyor 4 is brought to well 1, to which ammunition 5 is fed from a specialized rail or wheel

From" the platform 6 using an automated pusher 7 controlled by an automated rack 8 equipped with a sensor 9 of the position of the platform with ammunition. The platform 6 is discretely moved relative to the conveyor along the rail path 10 with the help of the winch 11, controlled by the rack 8 according to the information of the sensor 49 of the position of the platform 9. o When accumulating at the bottom of the well the required amount of ammunition and/or explosives, it has 4! a detonating device (for example, a mortar mine or a TNT bomb detonated from the surface with an explosive device) is provided and the ammunition is detonated. The case of involuntary detonation of munitions when their detonator collides with a well hole, in relation to the proposed technology, is also a regular process that "drive" 20 does not affect the overall sequence of work.

Under the influence of the high temperature of the explosion (about several thousand degrees), the shock wave and fragments from the outcrop rock, the wells are compacted with the formation of a strong camouflaged cavity 12, which provides the possibility of further multiple detonation of ammunition and explosives in it.

In the upper part of the casing pipe of the well 1, holes 13 are made along the perimeter, to which an aqueous solution of reagents, neutralizing harmful gaseous products of the explosion, is supplied through the pipe 14 from the container 15 through the nozzles 29. Explosive gases, passing at high speed past the openings 13, create a reduced pressure in them, as a result of which the aqueous solution of reagents saturates the gas flow. At the exit of the well, the explosive gases enter the nozzle 16, which is installed vertically above the well, coaxially with it. There are 17 grates (made of vertically arranged metal strips) at the entrance of the nozzle, which prevent the penetration of fragments into the 60 nozzles. The upper part of the nozzle is equipped with a gas flow splitter 18, which divides the flow into three equal parts and directs it through the valve gates 19 into the pipelines 20. These pipelines are located symmetrically in the horizontal plane (adjacent angles between them are 120 degrees) and as a result are mechanically balanced relative to the action gas flows associated with high-pressure storage tanks 21. These tanks are ringed with each other by a pipeline, from the outlet of which, after the valve 22, the compressed gas can be sent to a gas turbine with an electric generator.

Disposal of munitions according to the proposed technology in a large-diameter well at a depth of at least 10-15m is completely safe due to the exclusion of flying fragments, is environmentally friendly and allows you to utilize the energy of explosive gases and extract non-ferrous and black metal scrap from the well (with special equipment). At the same time, the proposed technology provides the possibility of destroying ammunition of various types, calibers and sizes without reconfiguring the main equipment of the technological complex.

The detonation well can be located at a short distance (from 200 to ZOOm) from the place of ammunition storage, withstand many detonation cycles (up to several thousand or more) with the possibility of destroying up to 100 kg of ammunition in one cycle with ten or more cycles per daylight. 70 Sources of information: 1.
