Description

TECHNICAL FIELD

[0001] The utility model belongs to rock burst prediction technical field, especially relate to a rock burst prediction device for lead-zinc mine deep roadway. BACKGROUND

[0002] The lead-zinc mine deep roadway refers to the roadway formed in the process of lead-zinc mining as the mining range continuously extends to the deep part. The lead-zinc mine deep roadway faces various challenges in the design and construction process, including but not limited to poor rock mass stability, ground stress testing and support scheme optimization, etc. It is necessary to control the rock burst prediction device to predict rock burst in the lead-zinc mine deep roadway to increase the safety of mining personnel working inside the lead-zinc mine deep roadway. Rock burst prediction refers to the process of predicting and warning the occurrence of rock burst through certain methods and means.

[0003] According to the patent literature with the patent announcement number CN220621970U, a rock burst prediction device for iron mine deep roadway is disclosed, which belongs to the field of rock burst prediction technology and includes a main board. The top end of the main board is fixed with a machine body. Two groups of symmetrical slide rails are fixed on the inner walls of the machine body. A first slide plate and a second slide plate are respectively slid on the two groups of slide rails. A rock mass acoustic emission detector is installed at the top end of the first slide plate. A controller and an information processing module are installed at the top end of the second slide plate. When the temperature inside the machine body is too high, the motor operates to drive the fan to rotate, allowing the fan to blow air inside the machine body, thereby allowing cool air from the outside to enter the machine body, achieving rapid cooling effect, and solving the problem of poor heat dissipation effect in the traditional device. When the device moves, the bottom plate is pressed, and the bottom plate moves slightly up and down under the action of the second spring, achieving the effect of shock absorption.

[0004] However, it still has the following disadvantages in actual use:

[0005] 1. The rock burst prediction device for iron mine deep roadway has a heat dissipation box fixed at the top end of the machine body, and a motor is installed in the heat dissipation box. The output end of the motor is fixed with a fan. When the temperature inside the machine body is too high, the motor operates to drive the fan to rotate, allowing the fan to blow air inside the machine body, thereby allowing cool air from the outside to enter the machine body, achieving rapid cooling effect, and solving the problem of poor heat dissipation effect in the traditional device. However, the position of the fan cannot be adjusted, which reduces the area of the fan for air cooling inside the machine body, and further reduces the heat dissipation efficiency inside the machine body.

[0006] 2. The above-mentioned rock burst prediction device for deep tunnels of iron ore has a snap-on structure including a clamping block fixed above the outer wall of the machine body, an inner cavity is opened at one end of the clamping block facing the machine body, a first spring is fixed on the inner wall of the inner cavity, a clamping plate is fixed at the other end of the first spring, and the end of the clamping plate away from the first spring passes through the inner wall of the machine body and is arranged at the front end of the slide rail. It is only necessary to push the push plate to release the obstruction of the clamping plate to the slide rail, thereby facilitating the removal of the rock acoustic emission detector from the interior of the machine body for maintenance. However, external force needs to be applied to multiple push plates, which increases the workload of maintenance personnel.
