Abstract

The invention relates to a mining case and saves material resources by increasing the multiplicity of use of a sealer in a device for injecting a bonding composition into the rock. The device includes a sealer from an elastically deformable sleeve (UDR) 8 with an outer 9 and an inner 10 sleeve (m) at the ends. An injection tube (s) 11 is placed inside the UDR 8. It forms an annular space in the UDR 8. BARRIER M 9 is provided with an internal flood / 2/4 uu river partition 12. The latter is fixedly mounted on THE 11. It divides the cavity of the coupling 9 into two parts 13 and 14. Each part of M 9 is connected to the distributor 6 with the possibility of alternating communication with pump station and atmosphere. HpHbfd-causal to the UDR 8 cavity 14 is connected with its annular space, moreover, M 9 is mounted on IT 11 motionless. In drilled hole set sealer. One of the components of the bonding composition is supplied to the distributor 6, which falls into the cavity 14 M 9 and further into the annular space. At the same time, the UDR 8 increases in diameter and seals the hole. Next, the valve 6 is set to the neutral position. A bonding compound is injected into the rock. After completion of the injection, one of the components of the composition is fed to the distributor 6, which enters the cavity 13, creates pressure there and moves M 9 to the initial position. As a result, the UDR 8 expands in length and decreases in diameter. Hole depressurized. 2 Il, , V Yu with S (L eats CX) SP 00 SP FIG.

The invention relates to mining, namely, devices for injecting a bonding composition through boreholes into fractured rocks,

The purpose of the invention is to save material resources by increasing the multiplicity of use of the sealer in the device.

Fig. 1 is a diagram of a device for injecting a fastening composition through bore-holes into fractured rocks} in Fig. 2, a sealer, a longitudinal section,

. The device consists of a pumping station 1, supply lines 2 and 3 for supplying components of the fastening compositions, an offsetter 4, a supply line 5 for supplying one of the components of the bonding composition through distributor 6 to the sealant 7, which is deformable sleeve 8 with outer 9 and inner 10 couplings at the ends, I installed inside the injection tube 25: a teller tube 11 with a fixedly fixed {internal foam transverse intersection 12,

The discharge tube 1 1 forms inside the sleeve 8 an annular space of icTBO, the coupling 9 is made with the possibility of axial movement along the discharge tube 11, the partition 12 divides the internal cavity of the coupling 9 into two parts 13 and 14, each of which ,; through the distributor 6, alternately communicating with the pumping station 1 and the atmosphere, Cavity 14, when connecting to the sleeve 8, is connected to its annular space,

The device dp forcing the fastening compound through the holes into the fractured rocks works as follows,. .

The sealer 7 is installed in the drill, drilled in mud rocks, and through the pumping station 1 through the supply pipe conduit 5 one of the components of the bonding composition (for example, for a polyurethane bonding composition is a polyester composition) is fed to the distributor 6, and from it - into the cavity 14 of the coupling 9 and further into the annular space between the elastically deformable sleeve 8 and the discharge tube 11, the elastically deformable sleeve 8 of the sealer 7 increases in diameter and is shortened as the coupling 9 moves towards the bottom 14585852

The irregular tube 11 to the right (for example, by the size of 20 cm with the length of the elastic tube to the world of the sleeve 120 cm and its diameter 4 cm) and seals the hole.

Next, the distributor 6 is installed in the neutral position and, through the pumping station 1, the pressure pipelines 2 and 3 through the mixer 4 and the pressure pipe 11 are used to force the fastener into the fractured rocks. At the end of the injection process, to transfer the sealer 7 to the next hole, it must be depressurized. For this, through the pumping station 1, through the supply pipeline 5, one of the components of the fastening composition is fed to the distributor 6, and from it to the cavity 13 of the coupling 9 and, creating pressure, moves the coupling 9 to its original position, Elasticize the 1st arm to stretch and decreases in diameter. The component of the bonding composition, which is between the elastically deformable sleeve 8 and the discharge tube 11 in the annular space, flows through the distributor 6 into the atmosphere — or enters the discharge tube 11 for washing it, Invention Formula; A device for injecting a fastening composition through the dimples into fractured rocks, including a sealer from an elastically deformable sleeve with outer and inner couplings at the ends, and a discharge pipe placed inside the sleeve, forming an annular space in it, a pumping station, supply pipes and a distributor, characterized in that, in order to save material resources by increasing the multiplicity of use of the sealer in the device, the oversize coupling is provided with an internal transverse partition, the coupling cavity is divided into two parts, each of which is connected to the distributor with the possibility of alternating communication with the pumping station and the atmosphere, while the part of the coupling cavity adjacent to the sleeve is connected to its annular space, and the coupling is installed on the tube movably. 45 50 55 Editor M.Petrova Compiled by B, Usan-Podgornov Tehred M.Hodanich Order 342/39 Circulation 449 VNIIPI State Committee for Inventions and Discoveries at the State Committee on Science and Technology of the USSR 113035, Moscow, Zh-35, Raushsk nab. 4/5 Production and printing company, Uzhgorod, st.
