Description

one

; The invention relates to the field of mining, can be used when conducting mining at great depths, where heat release from surrounding rocks 5 causes workers to overheat.

Basically auth. St. 365477 describes a device to protect workers from overheating, including a screen mounted on a monorail, consisting of sections with channels through which coolant circulates.

A disadvantage of this device is that it does not provide thermal protection when loading the mountain moat 15 and erecting the permanent support.

The purpose of the additional invention is to increase the effectiveness of thermal protection when loading rock mass and erecting permanent support. 20

This is achieved by the fact that the device is equipped with a supporting frame suspended on a monorail, at the corners of which sliding telescopic rods are installed, and an additional 25 screen made of a sub-roofing, two wall and end sections consisting of separate leaves, the sub-roof section being placed on the supporting frame, two near-wall 30

the sections are hingedly mounted on the sliding telescopic rods along the walls of the mine workings, and the end sections are on the side of the mine workings, with the purpose of moving the additional screen beyond the main perimeter of the cross-section of the additional screen made more than the perimeter of the main screen.

FIG. 1 is a schematic diagram of a device for protecting workers from overheating, side view in the mine working face; in fig. 2 - section A-A of FIG. 1, in FIG. 3 - section bb FIG. one; in fig. 4 is the same with one flap of the end section, in FIG. 5 is a side view of the device with partially attached longitudinal and end sections of the auxiliary screen; FIG. 6 is a section view. In FIG. five.

The device for protecting workers from overheating contains a monorail 1, hung using fast-mounted suspensions 2 with rollers to the top x1m permanent support 3. To the monorail 1 using the bottom roller carriages 4 the main longitudinal screen 5 and the additional screen 6, Screens 5 are suspended separately and 6 can be moved along the monorail 1 along the longitudinal axis of the excavation.

The main longitudinal screen 5 repeats the shape of the production profile in which it will be placed. For example, it can be made vaulted, semi-circular or trapezoidal in shape and consists of sections 7, which have input 8 and output 9 channels through which coolant circulates. Section 7 are interconnected.

The auxiliary screen b, in the form of a repetitive production profile, consists of longitudinal sub roofing 10, wall 11 and end 12 sections. The wing-mounted section is placed on the supporting frame 13, at the corners of which sliding telescopic rods 14 are mounted, to which, in turn, wall 11 and end 12 sections are hingedly mounted.

Parietal sections 11 and end

12 consists of separate flaps 15, the position of which is fixed by means of clamps 16.

A stop 17 is mounted on the monorail 1. The movement of the screens is controlled from the console 18.

The perimeter of the cross-section of the additional screen b is made up of a largeIlie of the perimeter of the main screen. This provides the ability to move an additional screen behind the main screen, which, in turn, ensures that the air is carried directly into the space behind the main screen, mine the inside screen.

The device works to protect workers from overheating as follows.

The installation of the heat-shielding device is performed once, and then the screens 5 and. B. Are moved after moving the mine workings in a sequence and in a position depending on the type of tunneling operations being performed.

Workers located in the wellbore space of working from the console 18 move the additional screen 6 close to the bottom of the working. Frame

13 is fixed to the stop 17 mounted on the monorail 1. The flaps 15 of the additional screen 6 are hung and fixed with the help of the clips 16 V; in such a position that the breast.

Sections 7 of the main longitudinal screen are interconnected and connected by the input channel 8 to the coolant source, and the output channel 9 to the drain line. In this operating state, the main longitudinal screen 5 is extended as close as possible to the end section 12, overlapping a part or a significant part of the surface of the additional screen 6 (Fig. 1).

By changing the position of the wings 15 of the auxiliary screen, you can perform various tunneling operations of the tunnel cycle.

With the folded (or removed) one by one, redirection of one of the flaps 15 of the end section is followed by drilling holes and their loading.

 Having ventilated the mine face, extending the roofing sections 10 of the additional screen 6 to the bottom, and

 The main longitudinal screen 5, adjacent to the broken rock mass, is loaded onto the rock mass. As the rock is loaded onto the partially extended telescopic rods 14, they hang

5 longitudinal and end flaps 15 (Fig. 5 and 6). So having isolated a part, or the most part of the bottomhole space and reducing the heat transfer from the bottom hole mass and the bottomhole production space, immerse the rest of the rock mass.

Leaving insulated with the help of an additional screen 6, the face and walls of the bottomhole space and retraction of the main longitudinal screen into the fixed part of the excavation, permanent support was erected. As the permanent support is erected, the main longitudinal screen is shifted to the side of the bottom.

Q Raise the permanent support by the required distance, the main longitudinal screen is pulled out from the console 18 as close as possible to the end section, overlapping part or a large part

g of the surface of the additional longitudinal screen 6. Thus, under the full cover of screens 5 and 6 of the device for protecting workers from overheating, the miners again lay the temporary or permanent track,

0 arrange suction groove. That is, a new cycle of tunneling operations begins.

The proposed technical solution of the device to protect people from overheating provides additional protection against heat transfer from the massif at the bottom of the chest and near the bottomhole production space, where the heat transfer is greatest, during such tunneling works as loading of the rock mass and erecting the lining.

The device allows to increase the efficiency of thermal protection of workers working under the cover of the proposed device in ultra-deep mines and to avoid overheating of miners.
