Description

VESSEL FOR WATER BLOCK

The utility model relates to mining and is designed to deal with explosions of gas and dust in underground mines.

A device for a water barrier, containing a vessel of elastic material with holes for skipping the suspension and an arm for attaching the vessel to the top (USSR copyright certificate No. 1305389, class E21 F 5/00, published in BI No. 15, 1987). The main disadvantage of the known device is the evaporation of liquid from the vessels, and therefore requires constant monitoring of their filling.

Known water barriers made in the form of "water pockets from a special polyethylene film with weakened places located in the form of a pattern (KP Schulte et al." Water pockets made of polyethylene - an alternative to ordinary water barriers, J. "Gluckauf, 2002, No. 1 (2), pp. 11-16).

An empty pocket is hung on a square tube by a winding method with additional fixing with an adhesive cloth, and then filled with water through a hole in the upper part and a hole is sealed. Water "pockets have a flat side across the axis of the mine.

One of the main disadvantages of water barriers made in the form of water "pockets" is the difficulty of forming barriers depending on the shape and cross section of the workings and clutter is valid; their workings by the elements that make up the screen frame.

Another disadvantage of the water bag is its one-sided placement relative to the support, which determines

E21F5 / 00

A vessel for water barriers is proposed, containing an elastic shell with a device for pouring water into it.

The difference is that the shell is equipped with reinforcing elements located on opposite edges of the shell, with holes for connection with other shells.

Reinforcing elements can be made in the form of gaskets connected to the edges of the shell and additionally stitched along the longitudinal edges with two seams, and the holes are placed between these seams.

The installation of reinforcing elements at the edges of elastic vessels allows the formation of water barriers of various configurations depending on the cross section and size of the workings by connecting the vessels together.

The essence of the utility model is illustrated by the drawing, where in FIG. 1 shows a general view of a vessel for water barriers, in FIG. 2 - placement of vessels in the cross section of the working, in FIG. 3 - an example of the placement of vessels along the length of the output. The vessels 1 forming the water barrier are made in the form of a shell of an elastic material, for example, of a polyethylene sleeve with a thickness of 80-120 microns. The material should have favorable properties in relation to destruction under the action of the shock wave of the explosion, but at the same time sufficient strength and durability to work in standby mode. The vessel has an opening 2 for pouring water into it and a fixture 3 for tight closure. The holes can be in the form of slots or stamped in the wall of a pocket with a diameter of 3-4 cm, and patches made of duct tape, valves, etc. can be used to overlap them. The opposite edges of the vessel are used to connect the vessels to each other, for which they are glued to reinforcing elements on both sides, for example, in the form of gaskets 4, and along the longitudinal edges

the gaskets together with the edges of the vessel are stitched with seams 5. To connect the vessels to each other between the seams 5, stamp holes 6.

To place the vessels in the excavation, hard supports 7 are installed under the roof, made, for example, of pipes. Vessels 1 are hung on supports in one or two rows, which, with the aid of brackets 8 or ties using holes 6, are attached to rigid supports (when placed; in one row) or interconnected (when placed, in two rows ) For placement below the vessels located, no additional rigid supports 7 are required, since these vessels are attached with brackets 8 (or ties) directly to the lower edges of the upstream vessels. Thus, a water barrier is formed in the mine from individual vessels, without the use of intermediate rigid supports. Barriers from such vessels can be raised to the roof and vehicles can be passed into the protected area. In an explosion, a shock wave breaks the vessels and sprays water from them over the entire cross section and length of the mine. The layout of the vessels can adjust the density of water droplets in separate places of the screen.

The presence of gaskets and the method of connecting them with the vessel ensures the reliability of the connection of vessels between themselves.
