Description

(54) MINE REACHABLE

one

The invention relates to mining and can be used for underground mining of mining systems with laying of the worked out space for mining mines.

A known shaft bridge includes a frame made with a perimeter chute, two elastic sealing elements, one of which is filled with water and the other with air, and a pressure shield attached to the frame covered with elastic waterproof material and fitted with pipes for drainage water and sampling 1.

The disadvantage of this jumper is the complexity of the design and the hard work of installing it.

Also known shaft jumper, including the curtain, a rigid frame with a chute around the perimeter and an elastic sealing element, made in the form of a single cylinder 12}.

However, this jumper does not provide sufficiently reliable sealing of the excavation, as a single cylinder filled with air is able to compensate for only minor irregularities of the walls, roof, and soil, whereas in practice the contour of development almost always deviates from the design one. Therefore, at the place of installation of this jumper, it is necessary to protect the surface of the workmanship, which is associated with laborious manual work.

The purpose of the invention is to improve the sealing production and simplify the installation of jumpers.

The goal is achieved by the fact that in the shaft bridge, consisting of a rigid frame, made with a groove in the example and an elastic sealing element, the latter is made of separate cylinders, each separately connected to the supply line of compressed air, each rigidly equipped with plates fixed to its side walls, which are / are connected to the walls of the gutter by means of radial guides with the possibility of moving along them. In addition, each bappon in OCIIOESNIN is made corrugated. FIG. 1, the proposed mine shaft is shown, a cross-section of the insulated excavation; in fig. 2 shows section A-A in FIG. 1. The jumper consists of a rigid frame 1, made with a groove 2 around the perimeter, and an elastic sealing element, assembled from individual cylinders 3, which are installed in the groove 2 and individually connect a cable with an air line 4 of compressed air. The side surfaces of the cylinders 3 are rigidly attached to the plates 5, which are connected with the walls of the support 2 by means of radial guides 6 with the possibility of moving along them. Each cylinder 3 at the base is corrugated. On the lower corners of the jumper brackets fixed 7. The jumper works as follows. With the help of brackets 7, the jumper is installed on wooden bars laid in the corners of the mine. Then, compressed air is supplied to trunk 4, which enters the balloons 3. As they are filled, the cylinders begin to be pulled out of the groove 2 due to the presence of the corrugated sections, and the plates 5 are carried along. Since each cylinder is filled individually, it moves independently of others and continues until contact with the working surface. After that, under the influence of increasing air pressure, the cylinders start to inflate, but the increase in the volume of each cylinder is limited: from two sides — by plates 5, with one — by the working surface, and, on the other, by the bottom of the groove 2. Consequently, the volume increase of each of cylinders may occur due to swelling of only two of its faces, namely those facing the adjacent cylinders, as a result of which gaps between them are formed. The use of the proposed jumper to isolate mine workings during the laying of the goaf space eliminates the time-consuming manual work of cleaning and special preparation of the working surface at the jumper construction site, as well as reduce the number of jumper installation operations. In general, the proposed lintel design provides reliable sealing of the production. Claims 1. Shakhtna jumper, including a rigid frame, made with the chute. perimeter, and an elastic sealing element, which is so that, with a chain to improve sealing and simplify the installation of the jumper, the elastic sealing element is made of separate cylinders, each separately connected to the supply line of compressed air, while the cylinder is rigidly fixed on its side walls are plates that are connected to the walls of the gutter by means of radial guides with the possibility of moving along them. . 2. The bridge according to claim 1, in accordance with claim 1, that each canister at the base is corrugated. Sources of information taken into account during the examination 1.
