摘要
针对DTC-150防爆地质超前探测仪在工程应用中存在的解释成果误差较大的问题,提出了研制一种新型矿井多波多分量地震反射法观测系统的必要性;分析了煤岩有效地震波频率特性,提出新型矿井多波多分量地震反射法观测系统的有效布设方式为震源置于掘进面远端,采用一炮多收制;介绍了该系统中高速高精度多通道数据采集模块的电路设计;给出了该系统为消除掘进面绕射回波干扰和放炮形成的巷道声波干扰的处理方法。该系统已研制成功,实验结果表明,其本底噪声小,且具有较高的可靠性和稳定性。
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.
