Overview

The mining Rayleigh wave detector utilizes the principle of multi-channel transient surface wave exploration to detect abnormal structures in the front, side walls of tunnels, coal seam roof and floor, and other directions based on the different dispersion characteristics of coal mine structures and other geological anomalies

Product Details

The energy distribution of Rayleigh waves is limited to a thin layer medium with a free surface perpendicular to twice the wavelength range of Rayleigh waves. The detection depth of Rayleigh waves is limited and mainly used to solve shallow geological problems. Rayleigh waves have the advantages of high resolution, low construction requirements, lightweight instruments, fast detection speed, and good economic benefits for shallow thin layer exploration.

Scope of Application

1. Exploration of structures in front of the excavation, such as faults, fracture zones, and thinning of coal seams;

2. The side wings of the tunnel have been exposed for fault tracking and hidden structural exploration;

3. Detection of hidden structures and discontinuous geological bodies in the working face;

4. Detection of thickness and depth changes in the lower coal seam;

5. Detection of the thickness of the waterproof layer on the roof and floor of the roadway;

6. Detection for other purposes.

Product Features

1. Professional platform

The instrument adopts the latest A8 S5PV210 processor, with a main frequency of 1G, 512M DDR2 SDRAM, 1G NAND FLASH. The instrument adopts advanced technologies such as Σ - △ 24 bit ADC, STM32 professional data processing platform, and supports remote firmware upgrade to form a high-performance hardware data acquisition and processing system, which is practical, progressiveness, and novel.

2. Powerful functionality

The instrument is equipped with a 10 inch widescreen LCD display with a resolution of 1200 × 600. The waveform, parameters, and human-machine operation display are distributed reasonably and humanized. The data file management in the instrument adopts Linux file management method, which can easily realize functions such as file display, deletion, and export. The communication adopts the USB port of the computer, greatly improving the practicality of the instrument. The instrument supports dynamic coil vibration velocity detectors and velocity digital detectors, making it suitable for different detection environments. The instrument supports rapid on-site analysis of data to generate preliminary result maps, providing strong support for on-site work.

3. Strong data processing ability

The instrument has two methods for extracting dispersion curves: phase difference method and dispersion spectrum method. To meet the needs of on-site detection environment, effective methods can be selected to extract effective Rayleigh wave dispersion curves. At the same time, the instrument provides forward and backward dispersion curve function, and represents the detection results through professional simulated seismic curves.

4. Long detection time

The instrument is powered by a lithium battery pack with a nominal voltage of 6.4V and a capacity of 8000mAh. The continuous working time can reach more than 4 hours, and it also has protection functions for overvoltage, overcurrent, and short circuit.

5. Large detection depth

By using a specially designed seismic source signal excitation device, high-sensitivity detectors, and professional signal processing methods, the extremely low frequency part of the Rayleigh wave signal is preserved, providing strong support for increasing detection depth.

6. Stronger security

The main circuits of the instrument are all inherently safe circuits, and have passed the national MA safety mark review for mining products. They have been manufactured and produced according to the approved drawings and technical documents according to the prescribed procedures, and have obtained the MA safety mark for the mining product. They can be safely used in environments such as gas and coal dust explosive mixtures.
