Description

BOTTOM INSTALLATION FOR

HYDRO AND HYDRO ABRASIVE AND

HARD MATERIAL PROCESSING

The invention relates to the mining industry, in particular, to devices for the destruction of coal, rocks and other solid materials by high-speed jets of water or water with the addition of an abrasive.

A known tool for hydro abrasive and processing of solid materials, used, for example, as a rock cutting body (RF patent No. 2109950, Е 21 045 / 04.1998, Bull. No. 12). For the tool to work, it is necessary to supply water under ultrahigh pressure, which is provided by the pumping station. In the case of operation in cramped conditions of the face, a large-sized pumping station is difficult to place near the place of work. Therefore, it is often forced to be placed at a great distance, while the length of the water supply hoses inevitably increases, which leads to a significant decrease in the pressure supplied to the tool.

The objective of the utility model is to bring the source of hydraulic energy as close as possible to the working place of the hydraulic tool, thus reducing the length of the connecting hoses.

To solve this problem, a downhole installation for hydraulic and hydroabrasive destruction of rocks and other solid materials is declared, containing a cutting tool, connecting hoses, a water supply source, in which, according to the proposal, the combine irrigation system or fire hose is used as a water supply source, and to increase pressure water flowing to the instrument.

- a -

that, to the required level, a hydraulic booster block is provided, connected by hoses to the pressure and drain emulsion lines of the mechanized complex. Hoses are made with the possibility of connection to the fittings of these lines. To eliminate the pulsation of the cutting strings, the installation is equipped with a receiver, and the tool is equipped with a container with abrasive material.

The drawing shows a diagram of the proposed installation.

An installation mounted on platform 1 is placed directly in the face and moves along the face of the face conveyor 2 (if

allow the conditions, it is advisable to place it directly on top of a shearer 3, as shown in the drawing). Tool 4 (in

in this case, in manual execution) is supplied with water, for example, from the irrigation system of a shearer. However, the pressure in the irrigation system is not enough to create a high pressure jet that can destroy

rock or coal mass. Therefore, the installation is equipped with a power steering unit 5 located on the platform 1 (or on the combine body) and connected by hoses b to the pressure and drain emulsion lines 7 of the powered roof support (Iekhkopleks). At the same time, for the connection, the fittings 8, serving, available on these highways, are used. Shchena for connection of sections of the mechanized support. Accordingly, the hoses also have end pipes providing such a connection. Since pulsation occurs during the operation of hydraulic booster, the installation is equipped with a receiver 9 to eliminate it, ensuring uniformity of the cutting jet ejected from the tool. The installation also provides a container (not shown) with abrasive material added to the water stream to increase cutting efficiency. .

amplifier 5, which with hoses b are connected to the emulsion magnetic line 7 (pressure and drain branches) of the powered roof support. In this connection is made to the fittings 8, closest to the place of work. After passing through the power steering unit 5, water from the combine irrigation system under a pressure of up to 2500 am is supplied through a high-pressure hose 10 to a hydraulic cutting tool 4 and is ejected from it by a jet (thickness does not exceed 1 mm) at a speed of up to 1 km / s, destroying the processed section of the pedigree or coal mass. If you need to move to another place of work, the hoses 6 are connected to other fittings 8 closest to the new place of work.

The use of a low-pressure fire network as a source of water supply for the irrigation system of the ILE combine in combination with hydraulic boosters that increase the pressure to the level necessary for the tool to work, eliminates the need for a bulky pump station in the bottom and significantly reduces the length of the connecting hoses.

The installation is explosion and fire safe, as well as environmentally friendly. It does not have any electrical components; during its operation, the emission of dust gases is excluded. Water consumption is negligible. A jet of water, striking into the processed material, turns into steam, which is carried away by the ventilation stream, so the soil remains dry.

The unit is intended for use in complex mechanized working faces of all types and power intervals. With its help, it is possible not only to destroy the coal of the rock mass, but to carry out any other work that may be necessary during mining of lava:

destruction of a solid rock mass in zones of geological disturbances during the replacement of a coal seam with rock; destruction of the roof to release the clamped upper; destruction of soil rocks for the movement of the support section buried in the soil;

the destruction of large rock blocks or coal oversized;

cutting metal structures etc.
