Problems solved by technology

[0004] However, due to the particularity of the working environment of the gas hole sealer, after the manufacturer has produced the "two plugs and one injection" type gas hole sealer, it is impossible to visually observe the working process of the hole sealer, and it is also impossible to find out the defects of the hole sealer. question
If the gas hole sealer with quality problems is directly used in the mine, the gas drainage effect will not be good, and a major accident will occur

Embodiment 1

[0031] Embodiment 1: as Figure 1-3 As shown, a ground simulation experiment device for gas sealing, including a mixing box 1, an air compressor 2, a diaphragm pump 3 and a simulation pipe 4; the top side of the mixing box 1 is provided with a feeding port 5; the diaphragm The feed port of the pump 3 is connected with the mixing tank 1 through a pipeline, and the air inlet of the diaphragm pump 3 is connected with the air compressor 2 through a pipeline; Fixed on the ground by anchor screws, the gas sealer 6 is placed inside the simulated pipe 4, and the grouting pipe 7 on the gas sealer 6 is connected to the discharge port of the diaphragm pump 3 through a pipeline, and the diaphragm pump 3 A quick-plug connector is installed on the pipeline between the grouting pipe 7 to facilitate quick disassembly.

[0032] One side of the top of the mixing box 1 is provided with a water inlet 9, and the water inlet 9 is connected with a water tap through a pipeline to achieve the purpose...

Embodiment 2

[0041] Embodiment 2: This embodiment is different from Embodiment 1. The difference is that Embodiment 1 cannot simulate the sealing process of multiple angles; and in this embodiment, the above-mentioned defects can be avoided, specifically:

[0042] It also includes an angle adjustment mechanism fixedly connected to the bracket 8; the simulated pipe 4 is fixedly connected to the angle adjustment mechanism, and the angle adjustment mechanism rotates to make the simulated pipe 4 move within the range of 0-90°; the angle adjustment mechanism includes Rotating plate 16, base plate 17, driver 18 with self-locking function and two support plates 19; one end of said support plate 19 is welded to the top of support 8 symmetrically, and the other end extends to the outside of support 8; The plate 16 is rotatably connected between the two support plates 19 through the rotating shafts on both sides, bearings are installed at the connection between the two rotating shafts and the support...

Abstract

The invention discloses a gas hole-sealing ground simulation experiment device. The gas hole-sealing ground simulation experiment device comprises a mixing box, an air compressor, a diaphragm pump anda simulation pipe; a feeding port is formed in one side of the top of the mixing box; a feeding port of the diaphragm pump is connected with the mixing box through a pipeline, and an inlet of the diaphragm pump is connected with the air compressor through a pipeline; the simulation pipe is made of a hard transparent material and is disposed on a bracket, a gas hole packer is placed inside the simulation pipe, a grouting pipe on the gas hole packer is connected with a discharge port of the diaphragm pump through a pipeline; a water inlet is formed in one side of the upper part of the mixing box, and a stirrer is fixedly connected to the top of the mixing box; and a gas inlet of the stirrer is connected with the air compressor through a pipeline, and a gas regulating valve is further fixedly connected to a gas inlet of the stirrer. The gas hole-sealing ground simulation experiment device can simulate the working process of the gas hole packer, the produced gas hole packer can be sampledand tested in batch, the working process of the hole packer can be visually observed, and problems existing in the hole packer can be found and solved.

Description

technical field [0001] The invention relates to the technical field of hole sealing for underground gas drainage in coal mines, in particular to a ground simulation experiment device for gas sealing holes. Background technique [0002] More than 90% of coal mines in my country are mined underground, while high gas mines and gas outburst mines account for 48%, and the problem of gas disasters is extremely prominent. According to statistics, gas disaster accidents account for 70% of the seven major coal mine accidents in my country, becoming the number one factor restricting safe production in high gas mines. In order to ensure the safe mining of high-gas coal seams, before the normal mining of the working face, the underground coal mine production site generally arranges certain drainage boreholes in the coal seam, installs drainage pumps, and extracts through negative pressure until the gas content in the coal seam is reduced. reduced to a safe value. The effect of gas dra...
