Research of Key Technologies of a Novel Multi-wave and Multi-component Exploration System with Seismic Reflection Method of Mine
Abstract
In order to solve the problem of biggish error existed in interpreting result of engineering application of DTC-150 explosion-proof advanced geology detector, the paper put forward necessity of developing a novel multi-wave and multi-component exploration system with seismic reflection method of mine. It analyzed characteristics of frequency of effective seismic wave in coal-rock, and put forward that effective distributing way of the system is laying seismic source in distal area of heading face and adopting once stimulate multi-channel receiving method. It also introduced circuit design of multi-channel data acquisition module with high speed and high precision of the system, and gave treating methods for eliminating interferences of diffraction wave of heading face and sound wave in tunnel caused by blasting. The system has been developed. The experiment result showed that the system has a little background noise and high reliability and stability.
