Embodiment 1

[0040] see Figure 1-4 , the injection method includes the following steps:

[0041] S1: First move the storage truck 1 to the working area, inject components A and B into the material storage cavity 2 of material A and material storage cavity 3 of material B respectively, and drill the rock wall of the working area, and then Insert the injection rod 4 into the drilled tunnel, and the top plate 21 is placed on the inner wall of the tunnel;

[0042] S2: Before injection, first rotate the movable ring gear 13, the movable ring gear 13 drives the screw 15 to rotate through the intermediate gear 14 and the guide gear sleeve 17, and then pushes the sealing strip 18 to move in the gas transmission groove 16, and the gas passes through the gas transmission pipe. 121 is input into the sealing airbag ring 12, so that the sealing airbag ring 12 expands and contacts the inner wall of the hole, and the injection rod 4 is fixed by the sealing airbag ring 12 in conjunction with the slurry ...

Embodiment 2

[0054] see figure 1 and Figure 5-8 , the top of the injection rod 4 is embedded with a motor 19, and the output end of the motor 19 is connected with a separation column 20, and the bearing of the separation column 20 is installed on the top of the injection rod 4, and the top bearing of the separation column 20 is connected with the top plate 21, The output shaft of the motor 19 is meshed with a movable tooth sleeve 25 through the toothed disc 22, and the movable tooth sleeve 25 is sleeved on the guide post 24, and the guide post 24 bearing is installed in the air extraction slot 23, and the air extraction slot 23 is opened. Inside the injection rod 4, the middle position of the guide post 24 is connected with another separation post 20 through the first bevel gear transmission assembly 241, and the separation post 20 is installed on the outer side of the middle of the injection rod 4 through the transverse seal and the guide post 24 A fan assembly 27 is connected to the bo...

Abstract

The invention discloses a high-molecular chemical coal-rock mass reinforcing agent for a coal mine and an injection method thereof, and the injection method comprises the following steps: S1, firstly, moving a storage vehicle to a working area, and respectively injecting a component A and a component B into a material A storage cavity and a material B storage cavity; s3, the raw materials in the A material storage cavity and the B material storage cavity are conveyed to a static mixer by a pump through a second conveying pipe and a first conveying pipe; and S4, a motor is started, the bottom of the guide column drives a fan assembly to rotate through a second bevel gear transmission assembly, air in the hole channels is pumped out from an air pumping groove and an air pumping hole, meanwhile, the guide column drives separation columns transversely distributed on the injection rod to rotate through a first bevel gear transmission assembly, and air in the hole channels of the blocked air bag ring partition is sucked. According to the high-molecular chemical coal and rock mass reinforcing agent for the coal mine and the injection method thereof, partitioned injection and diffusion are achieved, meanwhile, internal air is extracted in real time, bubbles are avoided, and the strength of the coal and rock mass is improved.

Description

technical field [0001] The invention relates to the technical field of coal rock mass reinforcement, in particular to a polymer chemical coal rock mass reinforcement agent for coal mines and an injection method thereof. Background technique [0002] In the process of coal mining, broken coal and rock mass will be formed due to geological structure, primary cracks and mining pressure, which will easily lead to fragmentation and roof fall in the working area, affecting mining safety and seriously restricting the mining progress. , the prior art adopts the grouting process, by injecting a reinforcing agent into the coal rock mass, and the coal rock mass is reinforced after infiltration and expansion, but the existing coal rock mass reinforcing agent and its injection method have the following problems in use : [0003] In the prior art, the injection rod is usually inserted into a pre-drilled hole for grouting operation, and the reinforcing agent is extruded from the front end...
