Abstract

This invention relates to mining, and b. used in the construction of near-coal coal and rock vertical bunkers. The goal is to reduce the labor intensity of work and increase the pace of construction of vertical mine workings of the bunker complex. The method includes the penetration of bunker 1, the construction of a shaft shaft (AL) 2, its fastening in the area adjacent to the bunker 1. When conducting AL 2 in the first construction period with the approach of the slab 5 to the site the contact between the loop 2 and the bunker 1 from the loop 2 to the zone of the bunker I is drilled transverse holes 6 for the length of the entry. They are blown up by camouflage charges with the formation of a safety screen made of crushed rock in bunker 1. Then the bunker 1 is driven by blasting the elongated holes through the section of the bunker 1. The broken rock of the bunker 1 is cleaned simultaneously with the cleaning of the protective shield rock. After this, the permanent support of the bunker 1. is erected 7 or Ј (/)

The invention relates to a mountain body and can be used in the construction of near-coal coal and rock vertical bunkers.

The aim of the invention is to reduce the labor intensity and increase the rate of construction of vertical mining workings of the bunker complex.

Fig. 1 shows the stage of drilling holes and charging the body of the bunker from the bottom of the shaft in the first period of construction; Fig. 2 shows section A-A in Fig. 1; Fig. 3 shows section B - B in Fig. 1; Fig. 4 shows the stage of drilling from the same surface during the construction of the bunker in the second period of the structure, Fig. 5 shows section B-B in Fig. 4, Fig. 6 shows the bottom hole of the vertical mine workings after blasting the elongated holes, Fig. 7 - section G-G in Fig 6

The method of construction includes the drilling of the tanker 1, the construction of the shaft 2, its fastening in the zone of the bunker’s junction, the explosive destruction and the removal of the host rock, while forming a safety shield 3 of the crushed rock ahead of the installation of the support 4 from the mine 5 barrel 2 in the zones of the hopper 1 for pepper holes 6 and their blasting

The method also includes drilling with extended holes 7 around the safety screen 3 at the bottom 8 of the bunker 1 when passing postce in the second construction period charging and blasting the elongated holes 7 to the find, cleaning the broken rock H with crushed rock of the safety screen 3 for example , on the approach to the development of 10 and the construction of permanent lining 11 b nker 1

The method of construction of vertical mining workings is carried out

When conducting the shaft 2 in the first period, build a pillar with the approach of the bottom 5 to the part of the contact of the mine shaft 2 with the bunker 1 into the body of the latter, drill the transverse boreholes for 6 seconds in the following way and camouflage charges With the help of the Posta blasting units, the separation, the demolition, the centering of the formwork and the erection of reinforced lining

With the advancement of mine floor ia 2 at the site of contact with bunker oom 1, on the occult slab in that bunker 1, transverse boreholes are produced, followed by charging and exploding with a camouflage net charge, after what: oh so ot. the pole 1 has a gap, a descent, the centers of the hull and the reinforcement of reinforced lining 4

The list of activities is repeated throughout the entire contact area of the mine

trunk 2 with a hopper 1 As a result, a safety screen 3 in the form of crushed rock is obtained, which protects the erected reinforced support 4 from seismic

loads when blasting the elongated bore holes 7 at the time of the prokhot, ki of the bunker 1

The drilling of the Bcker 1 was carried out in the second construction period, after the shaft 2 was penetrated to the final depth, weighed constant vessels, when the complex of the workings of the near-barrel yard was combined

At the approaching excavation 10, the hopper 1 is fitted, technological waste is passed, the tunnel equipment is mounted, then the drilling equipment is lowered to the bottom 8 and the bottom 8 is drilled to the bottom 8 by the first drill holes. The length of the holes are taken according to the passport

0 drilling and blasting operations calculated for each specific case, depending on the geological and geological characteristics of the rocks. After smoking the bottom 8 of the hopper 1, the elongated holes 7 are charged and their blasting

After the blasting and aeration of the broken rock 9, the harvesting of the rock 8 is carried out together with the crushed rock of the safety shield 3 in the tank x with discharge at the approaching mine 10

0 After cleaning the broken rock 9 and the crushed porosity of the protection screen 3, the permanent support of the 11 bunker 1 is erected at the first stop

With the end of the work on the permanent mounting on the face 8, the drilling equipment is lowered into the drill hole of the elongated holes 7 to the second stop. At the same time, the work cycle repeats even the sweat end of the hopper 1

Claims (1)

Claim A method of constructing vertical mine workings of a bunker complex, including sinking a mine shaft, securing it in the adjoining zone of a bunker, subsequent sinking of a bunker by blasting holes, cleaning the rock and erecting a support for the bunker, characterized in that, in order to reduce the complexity of the work and increase the rate of construction of vertical mine workings of the bunker complex, before mounting the mine shaft from it into the bunker zone, drill transverse bore holes to the length of the drill and blast them with camouflage charges to form a safety screen in the hopper of crushed rock, whereupon driving of the hopper is carried out by blasting of holes elongated section hopper, and the hopper cleaning breed performed simultaneously with the cleaning of rock safety screen.
