The main purpose of backfilling is to prevent surface subsidence, reduce the impact of ground pressure and earthquakes, and also to provide support for subsequent mining operations. However, some problems still exist in the actual operation of the backfilling process.
[0003] Currently, most existing detection methods rely on manual operation or simple mechanical equipment, resulting in low accuracy and efficiency, and failing to reflect changes in filling quality in real time. Especially in complex and enclosed underground tunnels, traditional detection methods are ill-suited to varying terrain and filling conditions. Utility model content:

This device can detect the height of the backfilling material in real time and accurately, providing reliable data support so as to adjust the backfilling process in a timely manner and ensure backfilling quality and mine safety.
[0005] A real-time detection device for the backfilling quality of underground mine access roads includes a height identification front-end system and a data acquisition module. The height identification front-end system is located below the backfilling return air inlet, and the data processing system is located at the control terminal in the central control room.
[0006] Preferably, the height recognition front-end system includes a three-dimensional laser emitter, a power supply device, a central control system, a telescopic device, a signal transmitting device, and an insulating housing. The three-dimensional laser emitter is connected to the telescopic device, and the telescopic device is connected to the insulating housing. Two three-dimensional laser emitters and telescopic devices are symmetrically arranged on the lower side of the insulating housing. The power supply device, the central control system, and the signal transmitting device are interconnected inside the insulating housing via wiring.
[0007] Preferably, the data acquisition module includes a signal receiver and a data processing system, wherein the signal receiver is connected to the data processing system via a line.
[0008] Preferably, the signal receivers are capable of wireless communication with each other.
[0009] Preferably, the height recognition front-end system, the three-dimensional laser emitter, the power supply device, the telescopic device, and the signal transmitting device are all connected to the central control system. The central control system adjusts the telescopic distance of the telescopic device and the rotation angle of the three-dimensional laser emitter in real time according to the point cloud data collected by the three-dimensional laser emitter, monitors the filling quality at different locations, and transmits the data to the data acquisition module through the signal transmitting device.
[0010] Preferably, the data processing system performs visualization processing on the collected data received by the signal receiver and feeds it back to the filling system.
[0011] Throughout the filling process, height data is continuously monitored and dynamically adjusted to ensure filling quality and safety.
[0012] This invention provides a device and method for detecting the quality of backfilling in underground mine access routes. Utilizing a three-dimensional laser emitter and a real-time data processing system, it can accurately measure and dynamically monitor the backfilling quality, ensuring that the backfilling operation meets predetermined standards, improving the accuracy and efficiency of the backfilling operation, and significantly enhancing the safety and stability of the mine.
