Abstract

Based on the results of monitoring with a temporary seismic network in the southern Kuzbass in an area of technogenic seismic activation that formed during simultaneous impact of open and underground coal mining, the article presents a detailed study of the spatial structure of this activation, its development over time, and its relationship with tectonic faulting. Seismic activation near underground workings is differs in the locality of the area and a large number of earthquakes with local magnitudes of M_L ≤ 2 (Bormann, 2002). For three closely located coal mines, general seismic activation is observed, within which, as a local zone, there is activation of underground workings characterized by strong earthquakes with M_L = 3–4. The focal depths have a bimodal distribution with maxima in the 1–1.5 and 2–3 km ranges. Both in the area of underground mines and open mines, the deep interior is seismically activated much deeper than mining works, while the seismic process is unsteady and pulsating in time.

监测Kaltan露天矿和Alardinskaya矿区（库兹巴斯）的地震活动

摘要

根据在库兹巴斯南部地区发生的技术地震活动区域中的临时地震网络的监测结果，该区域是在露天和地下采煤同时受到影响时形成的，本文对这种活动的空间结构及其发展进行了详细研究随着时间的推移，及其与构造断裂的关系。邻近地下巷道地震活化是在该地区的本地和与本地量值大量地震不同中号_大号≤2（鲍曼，2002）。对于三个位置较近的煤矿，观察到了一般的地震活化作用，在该地震区内，作为局部区域，存在着以M _L强地震为特征的地下作业的活化作用。= 3-4。焦深具有双峰分布，最大值在1–1.5和2–3 km范围内。在地下矿区和露天矿区，深部内部的地震作用都比采矿工作深得多，而地震过程不稳定且随时间变化。
