Abstract

The invention relates to the mining industry and is intended to support the roof. The goal is to enable the use of lining on steep seams. Pneumatic lining is made of sections 1 and 2. Through one section combined into two groups. On the side of the bottom, a guide (H) 3 lining and H 7 of the hydraulic shifter (MF) 5 are installed. From the bulk side there are additional H 4 lining and H 9 MF. The lining sections of one group are connected with H 3. The sections of the lining of the other group are connected with H 4. The lining of the sections of the lining is made in the form of brackets. On steep seams, the lag of the middle sections when moving H 3 to the bottom is one step less than the gentle ones. The lining of the lining sections is made by the GP 5. The last .ra € relies on H 3 and 7 and the rope 8 (L moves along the bottom. Due to the fact that H 7 is stretched, and If 3 is unloaded, GP 5 pulls up H 3 attached to sections are also carried out. Also, sections connected with H 4 support are aligned. 4 Il.

Description

The invention relates to the mining industry and can be used to support the roof in the lavas of gently sloping to steep seams without the constant presence of people in the clearing face.

The purpose of the invention is to provide the possibility of using lining on steep seams.

FIG. 1 shows lining, general view, movement of an odd group lining to slaughter; in fig. 2 - the same movement of an even group of sections of the lining to the face; in fig. 3 shows the node I in FIG. one; in fig. 4 shows section A-A in FIG. 3

The pneumatic lining consists of two groups of pneumatic-balance sections 1 and 2. The lining sections of one group are connected to the downhole guide 3 of the lining, and the lining sections of the other group of the additional damming guide 4. The shifters 5 and 6 are identical. In the lava, depending on the organization of work, one mobile unit can be used, which is remounted to move the group, sections 1 or 2, or two mobile units are used. The Advancer 5 moves along the guide 7 of the Advancer and the downhole direction with a nipple 3 lining with a rope 8, and the Advancer 6 moves along the additional guide 9 of the advancer and a downtropping direction towards the four support with a rope 10. Movement of the advancer along the guides is carried out with the help of sliding clamps 11 attached to the housing 12 of the Advancers.

The housing 12 of the peredvizchika may have a different width. Therefore, the distance between the guides a, which defines the width of the loose bottomhole space 1, varies according to the conditions and technology of the reservoir development. On peredvizchik 6, the sliding grip 11, covering the guide 4 of the support, is positioned in such a way as to make a small acute angle with the direction of its movement. The sections are connected with guides by means of brackets 13, which at one end are connected to the girth .14 and the other end - to the guide 3 or 4 supports. A line 15 for supplying a pressurized working medium is disposed along the sections and secured to the brackets 13.

Pneumatic support works as follows.

In the initial position, the lining sections are located in one row at a center of SRI 1 from the bottom.

After the strip has been excavated, the minerals are located at a distance of a + g from guide 3 of support by the amount of the step of movement of the support plate g. The guide 7 is tightened, for example by a hydraulic jack or a winch, and in such a position is fixed on a retraction and ventilation drift. The sections 1 of the support are unloaded, the guide sections 3 on the ventilation and haulage drifts are moved towards the slaughter by a step of movement

The lining of the sections that are closest to the haulage and to the ventilation drift sections also move to the face at a distance of r, and in the middle of the lava, due to the presence of friction on the soil, the sections are not moved to the face or it is insignificant. On steep seams, the lagging of the middle sections when moving the guide 3 to the bight is one step less than

JJ on gentle. The alignment of the lining sections and their location at the same distance from the bottom is made by the mover 5, which is mounted on the rails 3 and 7 and the rope 8 is moved along the bottom. Since the guide 7 of the tensioning device 7 and the shaft 3 with the sections attached to it are unloaded, the transferor 5, moving the tensioned guide 7, pushes the guide 3 with the sections attached to it to the face. After moving the entire group of sections 1 to the bottom, they are bulging by supplying a pressurized working medium to them. After that, from the side of the worked-out space at a distance of a-d from the guide 4, the support is positioned towards the 9 of the mobile unit and tensioned in the same way as the guide 7. Then the sections of the support 2 are unloaded, the direction of the 4 on the ventilation and The haulage drift moves towards the face at a distance r (Fig. 2). On the guides 9 and 4 mounted the mover

5 6 and the rope 10 moves along the bottom, moving the unloaded sections 2 to the bottom. After all sections 2 are brought to the bottom, they are spread by feeding a pressure working medium. The cycle of dredging the mineral and moving the support sections is repeated. Claims Pneumatic lining, including guide lining installed on the side of the bottom, and lander guide, pneumatic tamper sections of lining, combined into one of two groups, sections of one of which are connected 924 on each side of the guide lining, and the lanyard support, connected skolz In order to allow its use on steep seams, it is equipped with additional flexible guide rails and peeler mounted from the intake side of the securing section, the links of which to the guides of the support are made in the form of brackets, while the securing sections of another group are connected to the guide in- structions installed from the embankment side.
