“…It was shown recently that small aperture seismic arrays (up to 3 km) are an efficient instrument for monitoring rela tively weak (M b < 2.5) seismic events on regional scale distances. Multichannel processing of the signals at a seismic array recognizes weak arrivals against the background microseismic noise, which opens a funda mentally new possibility to monitor the seismic state of vast territories (Sanina et al, 2008).…”

We consider a method for identifying the segments of localization of deformation processes within fault zones. The method is based on the results of seismic monitoring at a dense seismic network in California. For the first time, by analyzing the seismogenic structure of several fault zones, we highly accurately located the domains involved in active deformation processes. Three dimensional reconstructions show that these domains are a set of local segments each having a characteristic size of about 100 m, which is commensurable with the scale of the probable anthropogenic impacts on the geological medium. By the example of a region in the North Caucasus, it is shown that by combining observations at a regional seismic network and at a local group of stations successively arranged at several segments close to the fault zone, it is in principle possible to achieve an accuracy of locating the seismic events, which is sufficient for such reconstructions.

A site experiment is performed herein within a 100 m range using a high-frequency structure activity monitor to explore the impact of different factors on the microseismic source location and analyze the range of influence of the velocity model, number of stations, and array surface on the seismic source location. Moreover, the impact of wave velocity, velocity-free location algorithm, and position of the seismic source on the microseismic location error of mines is discussed by establishing the ideal theoretical model of the wave velocity location and with particle swarm optimization. The impact of the number of stations and tables on the location precision is also explored by using the microseismic signals produced by the artificial seismic source. The results show that, for the location model containing the velocity, the velocity error would greatly affect the location precision, and the velocity-free algorithm receives good location results. The location result is more satisfactory when the seismic source point falls in between array envelope lines. The seismic source location precision is in direct proportion to the number of stations. According to the experiment, within a 100 m range, when the number of stations is over 12, the effect does not significantly grow with the increase of stations; the number of tables affects the location precision; and the multitable location effect is significantly superior to the single-table effect. The research shows that the optimal station density is 0.0192%, and the appropriate sensor layout to form a multitable monitoring network may effectively enhance the microseismic source precision of mines through the selection of a velocity-free location model. On the contrary, the number of stations can be reduced on the premise of the allowable error of the seismic source location, which may effectively reduce the monitoring cost.

“…The seismic noise level in the area of its location, as shown in Fig. 2 (curve 5), was taken from (Sanina et al, 2008) and recalculated from displacements into accelerations by the formulas given in (Peterson, 1993). It is evident that this level is much higher than the NLNM, as well as the NPSD of the SM 3E sensors, even without optimization of the electronics; this is why the latter sensors were chosen for the seismic station.…”

The SSD 3 three channel seismic recorder and the ADSS 3 three component broadband stand alone digital seismic station based on the SSD 3 together with SM 3E seismic sensors were developed. The main advantage of this equipment in comparison with foreign and domestic analogs is simplicity and conve nience while maintaining high technical characteristics. The structure and operation of the seismic sensor and seismic recorder are considered, and their main technical characteristics are given. Laboratory, bench, and comparative tests of the seismic recorder and station demonstrated their working capacity and compli ance with the development goal. Based on the test results, the ADSS 3 seismic station was commissioned as a three component broadband observation point of the Mikhnevo small aperture seismic array. The data obtained using the ADSS 3 made is possible to study the structure of the crust and upper mantle of this region using the receiver function method.
