Abstract

FIELD: mining.
SUBSTANCE: present invention pertains to supporting mine tunnels and can be used in mining industry and tunnel construction. The method of supporting mine tunnels involves drilling holes, putting a net near the walls, fitting an arch support and putting sprayed plaster base-spread concrete. At the bottom of the goaf, between the line holes, holes are drilled with length, multiple of the deviation of the goaf in one cycle. The indicated holes are drilled within the limits of the specified outline of the goaf. Bars are put into the holes. The bars are joined to similar bars of the preceding installation. Between the bars and the walls of the goaf, a net is put. The latter, together with anchor bars, is pressed to the walls of the goaf by the arch support. The sprayed plaster base-spread concrete is then put. The invention provides for safe work in the bottom hole when constructing underground mines and structures in fractured ground and in conditions of high pressure, where it is necessary to install the support tightly against the bottom hole.
EFFECT: provision for safe work in the bottom hole when constructing underground mines and structures in fractured ground and in conditions of high pressure, where it is necessary to install the support tightly against the bottom hole.

Description

The invention relates to the fastening of mine workings and underground structures and can be used in mining and tunneling when removing workings in unstable and shock hazardous rocks.

According to safety rules, when driving workings in such rocks, the support should be erected close to the face.

Known methods of fastening, when the lining is displayed in the roofing of the workings close to the bottom in the form of retractable consoles of wooden and metal frames and arched links (Geleskul M.N., Karetnikov V.N. Handbook for fastening capital and preparatory workings. - M. : Nedra, 1982, p.145-150).

The disadvantage of such supports is their destruction during blasting operations conducted in the face during the drilling and blasting method of excavating workings.

Known anchor supports in combination with spray concrete (Shilkin P.I., Antonov Yu.M., Mikhailov V.P. Rational support for weak easily weathered rocks. G.Zh. 1970, No. 9, p. 34).

The disadvantage of this method is the insecurity of the bottomhole space, which reduces the safety of work during slaughter.

The closest technical solution is the method of building leading lining in the destroyed rocks, when the lining elements are hammered into the destroyed massif and under the cover of the lining the rock is cleaned in the face (Fedyukin V.A., Fedunets B.K. Reconstruction of mining enterprises. - M. : Subsoil 1988, p. 219).

The lining can be applied only in conditions of workings in the rocks completely disturbed to a loose state. And this is its flaw.

The noted disadvantages of the mounting methods reduce their technological capabilities.

The aim of the present invention is to increase the technological capabilities of the method of fastening mine workings.

This goal is achieved by the fact that in the known methods, including drilling holes (wells), installing arched and anchor supports, spraying sprayed concrete, in the bottom of the hole between the contouring holes, drill holes with a length that is a multiple of the output for the cycle, these holes are placed in within the design development loop, rods are introduced into the holes that are connected to similar rods of the previous installation, a grid is placed between the rods and the walls of the excavation, the latter together with the anchor rods are pressed against the wall of the drill quipment via arch support, and then applied shotcrete sprayed concrete.

The invention is illustrated by drawings, in which Fig. 1 shows a bottom view with the placement of holes for breaking rocks and holes in which rods are inserted, Fig. 2 shows a plan view of the bottom-hole portion of a mine with various stages of supporting support and the bottom-hole portion of the rock mass with in it with bore holes and a hole with leading lining, in Fig. 3 is a longitudinal section through the mine and in Fig. 4 is a section through the mine with the lining fully extended.

The method of attaching mine workings is as follows.

In the face 1 of mine 2, a set of holes 3 is drilled for care for one cycle. Between the contouring bore holes 4 are drilled bore holes (wells) 5 with a length that is a multiple of the length of the output of the development per cycle.

Rods 6 are introduced into the holes, into which they are connected by bundles 7 in the bottomhole zone with the rods of the previous installation. Between the rods and the walls of the excavation there is a grid 8, which together with the rods 6 is pressed by the arch support 9 and the anchor 10 to the walls of the excavation, after which concrete 11 is sprayed on the grid 8 and the rod 6.

The method allows for temporary fixing of the array directly in the face and permanent fixing in some lag behind the face.
