Seismic Detection Technology for Mining Face

1 Scope

This document specifies the data collection, observation system design, acquisition equipment, and equipment installation of seismic detection during mining in underground coal mines. and data collection, data processing, geological interpretation, and submission of results. This document is applicable to the faults, collapse columns, fracture zones and relative stress distribution in the working face of underground coal mines. Real-time dynamic detection and monitoring.

3 Terms and definitions

The following terms and definitions apply to this document. 3.1 seismic-while-mining detection The vibration generated by the coal mining machine when cutting the coal wall is used as the source of the earthquake. The receiving lines are laid in the tunnels on both sides of the working face to receive the signal. The vibration data is collected and processed to detect and monitor the geological structure anomalies and relative stress distribution inside the mining face. 3.2 effective wavefield The virtual source equivalent wave field is extracted from the vibration signal excited by the coal mining machine source using seismic interferometry technology. Note. Includes direct wave field and scattered wave field, which can be longitudinal wave, transverse wave or slot wave. 3.3 minimum mining-face-receiver distance The shortest distance between the survey line and the coal mining machine working face (see Figure 1). 3.4 During mining seismic monitoring, the number of measuring points set up in the tunnel on one side of the mining working face. 4.Data Collection Collect geological, tunnel exposure and drilling data of the mining face and related areas. Including but not limited to the following information. ......
