Abstract
Seismic researches are carried out for the purpose of exposure of geological breaking zones in the extraction pillars of coal mines (realized by “NTC Vostochnii” limited company (Kemerovo) and FSUE “SNIIGGiMS” (Novosibirsk) in Kuznetsk Basin, 2010 2011). Solving this problem could result in lowering the considerable expenses which mines suffer when a breaking zone is found that wasn’t expected or has uncertain configuration. With seismic data obtained with POCA-A autonomous station (patents RU 2366981, 90223, 103937), the registered wave identification is carried out, the systems of wave hodograph curves are constructed, the seismic tomography processing of waves passing through the medium is carried out, and features of coal-bed structure and borders of its erosion are specified.
