Description

Technical Field

[0001] The invention relates to the technical field of tunnel support, in particular to a coal mine rock burst tunnel support structure and a use method thereof. Background Art

[0002] Before the excavation of the shaft and tunnel, the rock mass is in a three-dimensional stress state, and a large amount of elastic strain energy accumulates in the high stress area. During the excavation of the shaft and tunnel, when the mining face approaches these areas, the equilibrium state changes due to construction disturbance or blasting vibration, and the elastic strain energy of the rock mass is suddenly released sharply at the weak point, causing the rock and ore body to suddenly erupt. Rock burst is mainly affected by many factors such as geological structure, ore body and surrounding rock structure properties, mining depth, hydrogeological conditions, etc. In the fold and fault structure zone, the ore body has high elasticity and strength, the top and bottom plates are dense, hard, with few cracks and large thickness, the surrounding rock has high water content, and the mine with a large mining depth is prone to rock burst. Therefore, it is necessary to install support frames inside the tunnel.

[0003] However, when the existing U-shaped steel tunnel support frame is in use, two column legs need to be installed at the two ends of the top beam. Since the height of the column legs is generally fixed, when the ground inside the tunnel is uneven, directly fixing the column legs to the ground through fixing components may cause the tunnel side walls to squeeze the tops of the column legs, easily causing them to deform. In addition, when connecting two adjacent groups of column legs, most of them are fixed through limiting components, and the steps for installation and disassembly are cumbersome. The limiting components also need to be stored separately, and the disassembly efficiency is low. Summary of the invention

After installation, the end of the column leg is engaged with the column. Since the top of the column is provided with a slot arranged in an "I" shape structure, when the column leg contacts the inner wall of the column, the column can support the column leg; then, operate The personnel then move the column legs upward according to the height of the tunnel. When the top of the column legs contacts the side walls of the tunnel, the positioning holes on the column legs can be connected with the rotating grooves on the columns. When fixing the column legs, the plug rods are inserted from the side walls of the columns into the column legs, so that the two ends of the plug rods are limited by the column legs and the columns.

Since the side wall of the sliding plate is fixedly mounted with a sliding rod, when it drives the sliding plate to slide in the sliding groove provided in the fixed block, the telescopic spring sleeved on the sliding rod can be squeezed. When the telescopic spring is in a compressed state, the limit rod fixed at the end of the sliding rod can be released from the sleeve rod.

[0037] Specifically, a method for using a coal mine rock burst tunnel support structure comprises the following steps:

[0038] S1: First, the support mechanism 1 can be assembled and inserted into the support mechanism 2, and the support mechanism 2 and the support mechanism 1 are fixed together using tools, so that the support mechanism 1 can contact the side wall of the tunnel;

[0039] S2: the positions of the supporting mechanism 1 and the supporting mechanism 2 are moved again, and the operator can fix the supporting mechanism 2 on the ground by means of a fixing assembly;

[0040] S3: Then, after pulling the limiting mechanism 4, the connecting rod 5 is engaged and installed in the sleeve rod 3 fixed on the supporting mechanism 2. The limiting mechanism 4 limits the connecting rod 5, and the two sets of supporting mechanisms 2 can be connected;

[0041] S4: Finally, the mounting mechanism 7 is engaged between the two sets of supporting mechanisms 2 to make the supporting mechanism 2 more stable.

[0042] When the present invention is in use, firstly, one end of the two column legs 102 with an arc-shaped structure is snap-fitted and installed together with the top beam 101, so that the two pull rods 102 can be connected. After installation, the end of the column leg 102 is snap-fitted and installed in the column 201. Since the top of the column 201 is provided with a slot 206 with an "I"-shaped structure, when the column leg 102 contacts the inner wall of the column 201, the column 201 can support the column leg 102; then, the operator moves the column leg 102 upward according to the height of the lane, and when the top of the column leg 102 contacts the side wall of the lane, the positioning hole 104 provided on the column leg 102 can be aligned with the rotating hole 104 provided on the column 201 The movable groove 203 is connected. When fixing the column leg 102, the insertion rod 205 is inserted into the column leg 102 from the side wall of the column 201, so that the two ends of the insertion rod 205 are limited by the column leg 102 and the column 201. Since the two ends of the insertion rod 205 can pass through the inner wall of the column leg 102, the positioning block 204 is threadedly installed on the two ends of the insertion rod 205 using a tool.

Since there are two sleeve rods 3 symmetrically fixedly connected to the column 201, one end of the connecting rod 5 is engaged. By inserting the connecting rod 5 into the installation groove 405 provided in the sleeve rod 3, the connecting rod 5 and the sleeve rod 3 can be engaged and connected. At this time, the slide plate 401 is released, so that the slide bar 407 drives the limiting rod 404 to slide into the limiting hole 6 provided on the connecting rod 5 under the reaction force of the telescopic spring 406. Since the limiting rod 404 and the limiting hole 6 are both arranged in a regular hexagonal structure, when the limiting rod 404 is engaged with the two ends of the connecting rod 5, the contact area between the limiting rod 404 and the connecting rod 5 can be increased, thereby facilitating the limiting effect of the limiting rod 404 on the connecting rod 5, so as to facilitate the operator to disassemble the column 201 during transportation;

[0044] When the two ends of the connecting rod 5 are snapped into place between the two sleeve rods 3, the two groups of support frames can be connected together through the connecting rod 5, and then the length of the support frame can be adjusted according to the length of the tunnel, which is beneficial to improving the use efficiency of the support frame; two groups of blocks 701 are symmetrically fixedly installed on the side wall of the column 201 close to the base 202, and the two ends of the clamping plate 702 are snapped into place in the middle of the two groups of blocks 701, so that the column 201 is located in the groove 703 provided at both ends of the clamping plate 702, thereby improving the stability of the column 201.

A method for using a coal mine rock burst tunnel support structure according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1: First, the support mechanism (1) is assembled and inserted into the support mechanism (2), and the support mechanism (2) and the support mechanism (1) are fixed together using a tool, so that the support mechanism (1) can be in contact with the side wall of the tunnel; S2: the positions of the supporting mechanism (1) and the supporting mechanism (2) are moved again, and the operator can fix the supporting mechanism (2) on the ground by means of a fixing assembly; S3: After pulling the limiting mechanism (4), the connecting rod (5) is snap-fitted and installed into the sleeve rod (3) fixed on the supporting mechanism (2). The limiting mechanism (4) limits the connecting rod (5), so that the two sets of supporting mechanisms (2) can be connected; S4: Finally, the mounting mechanism (7) is engaged between the two sets of supporting mechanisms (2), so that the supporting mechanism (2) can be made more stable.
