基于微震监测技术的田野文物防盗方法研究

Investigation on the safeguarding method of the field tumulus by the micro-seismic monitoring technique

国内外对于微地震监测技术的研究虽然并不成熟,但其在油气田、煤田、地热等领域的应用得到了快速的发展.本文在分析研究古墓等田野文物被盗时人为活动特点基础上,提出了采用微地震监测技术,通过建立微震动监测网,实现对田野文物防盗掘保护的实时监控的技术方法.该方法通过对地下半空间介质内地震信号的采集、传输、处理和识别,实现对目标区域内地下挖掘、爆破盗掘等犯罪活动的实时监控和报警.结合河南某古墓防盗掘监控系统的试验研究,详细讨论了系统构成,以及最大限度防止漏报,减少误报的技术措施.近两年时间监测结果表明,利用对盗墓时产生的微震动信号的监测,是古墓等田野文物防盗保护的较为有效的技术途径,弥补了现今安防技术对于地下活动监控的不足.

Though it is not ripe worldwide for the research, the micro-seismic monitoring technique has developed rapidly in those fields such as oil field, coalfield, and geothermal field. We have suggested that use micro-seismic monitoring technique to set up a micro-seismic monitoring net, and to achieve monitoring in time for protection of field historical relics, based on the active features when the field historical relics are digged. The method can continuously monitor the some activity such as the underground digging and exploring for robbing the tumulus in the objective area by sampling, transmitting, analyzing and identifying the seismic signals. We discuss the system constitute and the meas- ure of avoiding alarm failure and reducing the false alarm, which combined with safeguarding s35stem of the field historical relics in henna province. It can be concluded that it is available and efficacious by applying the micro-seismic monitoring technique to prevent from robbing the field culture relic such as tumulus through building the alarm system of micro-seismic monitoring through the two years monitoring experiment, and this method can make up the deficiency of the safeguarding technique for monitoring the underground activity.
