The presented geoinformation system is based on cloud service classification of natural and mining-induced seismic events. The data entropy-based models treat seismic signals as functions of a “waveguide” led from a seismic source to a seismic station. The quality similarity or distinction of the models is related with the genesis of seismic events. The service includes Google App Engine cloud calculating technologies, IRIS Data Management Center web-services and local seismic monitoring databases. The application of the cloud service to classifying unknown-genesis seismic events is illustrated by the examples. 相似文献

The present paper offers the parameter of anisotropy for the use in processing experimental data of the joint seismic and
electric monitoring with the aim of studying the process of consolidation in a fractured rock mass under a strong seismic
load. Based on the interpreted experimental results, a seismic-electrical model is constructed for the epicenter zone of the
Altai earthquake occurred on September 27, 2003.

CSIRO has recently developed a real-time roof monitoring system for underground coal mines and successfully tried the system
in gate roads at Ulan Mine. The system integrated displacement monitoring, stress monitoring and seismic monitoring in one
package. It included GEL multianchor extensometers, vibrating wire uniaxial stress meters, ESG seismic monitoring system with
microseismic sensors and high-frequency AE sensors. The monitoring system automated and the data can be automatically collected
by a central computer located in an underground nonhazardous area. The data are then transferred to the surface via an optical
fiber cable. The real-time data were accessed at any location with an Internet connection. The trials of the system in two
tailgates at Ulan Mine demonstrate that the system is effective for monitoring the behavior and stability of roadways during
longwall mining. The continuous roof displacement/stress data show clear precursors of roof falls. The seismic data (event
count and locations) provide insights into the roof failure process during roof fall. 相似文献

滑坡监测的重点是对滑坡体倾斜角变化的监测。针对目前滑坡监测仪器高精度、高可靠性、高自动化程度及高便携性的要求,提出了一种基于SCA100T和CC2530的无线滑坡监测系统。系统以STM32单片机作为主控MCU,采用SIM900模块实现GSM网络接入,基于9 V干电池,12 V、40 Ah蓄电池和小型太阳能发电系统完成系统持续供电;分为采集终端、采集站、接收主机3部分。采集站通过SCA100T传感器采集滑坡体倾角信息,各采集站和采集终端之间采用ZigBee进行通信,采集站基于GSM网络将数据发送至远程的接收主机。系统程序设计采用主动上传与定时上传相结合的机制降低功耗,利用短信触发或定时器定时触发,驱动倾角传感器采集,并启动GSM模块实现远程自动化传输。该系统倾角监测绝对精度高达0.035°。 相似文献

The safety control system for water-soluble mineral mining in complicated ground conditions is presented. The system is based on geomechanical interpretation of surface and underground seismic monitoring data. Mathematical modeling of water-impervious strata takes into account the whole set of geological and geotechnical factors determined from the seismic observations. It is shown that the seismic–geomechanical monitoring allows stress state control in waterproof strata, which ensures prompt decisionmaking on extra protection and minimizes accident risks. 相似文献

The seismic event with an energy of about 1.4·105 J, occurred at the Oktyabrsky Mine at the Talnakh-Oktyabrsky polymetal deposit on August 21, 2005 is described. This event
was the largest among those recorded by Norilsk seismic station for the whole observation period since 1993. It is shown that
the ratio of V
E
and V
K
, one being the velocity of the reduced center of the seismic energy emission, the other being the velocity of the migration
of separate seismic events until they make up a sequence ordered relative to their manifestation time for a zone of higher
stress concentration within a mine field may serve as a criterion of the observed rock mass transition to the critical state.
