Description

The present invention relates to methods of anti-mine support.

It is known that mine weapons are used to destroy or disable enemy surface ships, submarines and ships in the course of mine-protective actions [1, p. 249]. Usually, the Naval Forces seek to mine the enemy's exit fairways during a threatened period or with the outbreak of hostilities in order to prevent his fleet from withdrawing its ships from their bases.

Anti-mine support involves the implementation of a system of measures and actions to ensure the safety of ships (vessels) from being blown up by enemy mines in base areas, at base exits, at sea crossings and in combat areas. It includes: destruction (destruction) of warehouses, arsenals and bases of enemy mine weapons, and their carriers, organization of mine surveillance and mine warning, navigation along the fairways and recommended courses, a system for monitoring the state of the physical fields of ships, the destruction of ships and aircraft - directors mines, search and destruction of mines and minefields by anti-mine forces, ensuring the transition of formations of ships (convoys, landing units) and individual ships from mine explosions [1, p. 347].

The elimination of mine danger is a difficult task and requires long-term mine action using all available mine action forces and means, including minesweepers, mine action helicopters, mine breakers, mine detectors and mine destroyers, equipped with mine search and destruction tools and prepared to solve the problems of combating mine danger [ 1, p. 347].

One of the indicators of the effectiveness of mine action is the time to eliminate the mine danger. Existing methods for eliminating the mine danger in the fairways provide for mine action within several hours, or even days from the moment of its occurrence, required to survey the area, search for and destroy the discovered mines. The inability to eliminate the mine danger by known methods and anti-mine means in a short time is their main drawback.

A known method of clearing the fairway from bottom mines to ensure an emergency exit of ships (vessels) from basing points and forcing a mine-hazardous area using cord charges, adopted as a prototype of the invention, in which

- clarify the boundaries of the minefield only along the length of the blocked section of the fairway,

- calculate the minimum required width of the passage of ships (vessels) and the cord charge necessary for its punching,

- in advance or immediately after the discovery of mines, a cord charge (charges) is installed (lay on the ground) in the axial part of the fairway by a single ship or a group of ships to the minimum required width,

- detonate the cord charge using electric detonators remotely or by remote control,

- pre-arrangement of cipher charges is carried out in time, taking into account the service life of the charges and their explosion control equipment,

- the fairway, where the cord charges are laid, is closed for navigation of all ships and vessels [2].

This method has the following disadvantages:

- after the discovery of mines in the fairway, cord charges cannot be set in the shortest possible time, since it takes time to prepare them on the setting ships and for the possible clearing of the fairway with contact trawls,

- the method is designed to provide the minimum required width of the passage of ships and vessels,

- early placement of cord charges is limited by the service life of the charges and their explosion control equipment, and also entails restrictions on the use of the fairway, since after the cord charges are placed, the fairway is closed for navigation of all ships and vessels.

The aim of the invention is to develop a method for clearing the fairway, which allows to eliminate the mine danger that has arisen as soon as possible after its detection and at the same time does not restrict the passage of ships and vessels.

There are liquid explosives, which are a homogeneous solution at the molecular level of the two components of the oxidizer and fuel. Liquid petroleum products, such as kerosene, are used as fuel, and nitrogen tetroxide or, as in Tuoren panclastite, dinitrogen tetraoxide is used as an oxidizing agent [3]. A liquid explosive based on a binary solution of dinitrogen tetraxide and a liquid petroleum product stored separately is not dangerous and can be stored for a long time. The connection of liquid components can be carried out by pipeline in the shortest possible time. The advantage of using a binary ammunition (explosive) is the safety of its storage, transportation and maintenance under conditions that would lead to the activation of classical explosive mixtures [4].

The purpose of the invention is achieved due to the fact that a method is proposed for clearing the fairway, in which an extended explosive charge is detonated using electric detonators remotely or by remote control, characterized in that the width of the passage of ships and vessels is determined, ensuring their maximum safety of passage, and the required power of the extended charge for punching a given passage in a minefield, one or more blasting pipes of design capacity are laid in advance as an extended charge along the fairway, a two-component liquid explosive is used as a charge in the blasting pipe, the components of which are stored separately in tanks spaced at a safe distance, in a threatened period or with the detection of mines in the fairway, the components of the liquid explosive are pumped from the tanks through the pipeline into the blasting pipe, where they are mixed, and after filling the blasting pipe, the pipeline is blocked .

The implementation of the fairway clearing method is shown in Fig. 1, 2 and 3. The numbers on them indicate: 1 and 2 - storage tanks for components No. 1 and 2, respectively, 3 - pipeline for supplying liquid explosive components, 4 - mixer, 5 - disconnector, 6 - axis of the protected fairway, 7 - fairway, 8 - blasting pipeline, 9 - mine.

In FIG. 1 shows the initial state of the equipment in the absence of a mine hazard: the liquid explosive components are stored in tanks (1) and (2).

In FIG. 2 shows that when mines (9) are found in the fairway (7), the components of the liquid explosive are fed through the pipeline (3) to the mixer (4), where they are mixed and the liquid explosive is brought into an explosive state.

In FIG. 3 shows how the supply of components through the pipelines (3) is blocked, and the prepared liquid explosive is pumped into the blasting pipeline (8) and shut off with the help of a separator (5), ensuring the safety of the equipment after the blasting pipeline (8) is triggered.

Next, the demolition pipeline (8) is blown up and the mines (9) exposed in the fairway are destroyed.

The technical result of the invention is a method for clearing the fairway, which ensures, in the shortest possible time after the detection of a mine hazard, the destruction of bottom non-contact mines and the creation of a corridor of a given width for the passage of ships and vessels.
