Abstract

The invention relates to the mining industry and makes it possible to increase the strength of the strengthening of a mountain range. To do this, drill holes (W) 1 inclined to each other in one plane up to intersection 2, and in the mouth part of W 1 form an additional intersection 3. Intersection 2 W 1 is expanded. Intersecting W 1 form a series for the contouring of the breed pillars of a triangular shape. Then, a length of cable 4 is tightened in W 1. They pass it through all contoured pillars 5 to form loops 6. Rope 7 and 8 are pulled through loops 6 in the longitudinal and transverse directions. The ropes 7 and 8 are pulled. They are installed in the first and last W 1 injectors. The wellhead parts of the remaining bore-holes are sealed to intersect 3 with a quick-hardening mixture. Through the high-pressure hose, the reinforcement solution is pumped from the first Ø 1 into all subsequent Øs. When pumped, high-frequency vibrations are created at the end of the high-pressure hose with a vibrator. When a reinforcing solution appears at the mouth of the latter, Sh 1 is blocked off with a tap, the injection is continued at elevated pressure until F 1 is completely filled and cracks in the massif are formed. The valve is then shut off at the first W 1. The high pressure hose is disconnected. With a slight fracturing of the mountain range, the use of cable 4 and cables 7 and 8 is not necessary. 2 Il.

They are installed in the first and last W 1 injectors. Seal the wellhead parts of the remaining bore-holes before intersection 3 with a rapidly hardening mixture. Through the high-pressure hose, the reinforcing solution from the first 14 1 is injected into all subsequent sh. When injected, high-frequency vibrations are created at the end of the high-pressure hose with a vibrator. With the appearance of the reinforcing solution at the end of the last W 1, it is blocked off with a crane, the injection is continued under increased pressure until 14 1 is completely filled and the cracks in the massif are filled. The valve is then shut off at the first W 1. The high pressure hose is disconnected. If the rock mass is slightly wrinkled, the use of cable 4 and cables 7 and 8 is not necessary. 2 Il.

The invention relates to the mining industry, namely to the resin-ionic methods of strengthening the mountain assassin.

The purpose of the invention is to increase the strength of the mountain massif.

Figure 1 shows a diagram of the fortification of the mountain massif; figure 2 - 25 green I in figure 1.

The technology for strengthening rock mass is as follows.

From the hole of the drill hole 1 in one plane, obliquely through each other at the intersection 2. The bottom parts of the holes 1 are expanded to form an additional intersection with each other. The figures 1 form a series for delineating the breed pillars of a triangular shape. Then, a length of cable 4 is pulled into the holes 1 and is passed through all contoured pillars 5 to form loops 6. The ropes 7 and 8 are pulled through loops 6 in the longitudinal and transverse directions and pull them. Injectors 9 are installed in the first and last bore-holes. The wellhead parts of the remaining bore-holes are rep-tagged to the place of their intersection with a rapidly hardening mixture (for example, a sand-plaster mixture). A high-pressure hose (not shown) is connected to the pipe 10 of the injector 9. The injection is made through the high-pressure hose of the reinforcement solution from the first hole into all subsequent interconnected holes.

During pumping, high-frequency oscillations are created at the end of the high-pressure hose by means of a vibrator (not shown). When a strengthening solution appears in the mouth of the last bore 55

The valve is blocked with valve 11 and the injection is continued under increased pressure until the holes and cracks in the massif are completely filled. Then, the valve 11 of the injector 9 in the first hole 1 is shut off and the high-pressure hose is disconnected. With a slight fracturing of the rock mass, the use of cable 5 and cables 7 and 8 is not necessary.
