Chinthu chodabwitsa chinapezeka mu mgodi wa malasha mumzinda wa Donetsk ku Ukraine mu 2008. Chifukwa cha mmene mwala wa mchengawo unamangidwamo, chinthu chodabwitsa chomwe chimafanana ndi magudumu akale mwina chidakali mkati mwa mgodiwo.
Ogwira ntchito anali odabwa kuona chooneka ngati gudumu pamwamba pawo padenga lamchenga la ngalande yomwe anali atangofukula kumene pamene akubowola coking stratum yotchedwa J3 'Sukhodolsky' mozama mamita 900 (2952.76 ft) kuchokera kumtunda pamwamba.
Mwamwayi, ndiye Wachiwiri kwa Chief VV Kruzhilin anajambula chosindikizira chachilendo ndikuchigawana ndi woyang'anira mgodi S. Kasatkin, yemwe adalengeza za kutulukira pamodzi ndi zithunzi zodabwitsa.
Popanda kufotokoza momveka bwino momwe ma gudumu adatulukira, zidadziwika kuti dera la Rostov lozungulira Donetsk lili pa thanthwe la carboniferous la zaka zapakati pa 360 ndi 300 miliyoni zapitazo, ndipo makala oyaka moto omwe amafalitsidwa kwambiri amachokera pakati mpaka pakati. mochedwa Carboniferous, kutanthauza kuti kusindikiza kungakhale zaka 300 miliyoni.
Malinga ndi ambiri akatswiri amalingaliro, izi zingatanthauze kuti gudumu lenileni linakakamira zaka mamiliyoni ambiri zapitazo ndipo linasweka pakapita nthawi chifukwa cha diagenesis, njira yomwe matope amapangidwira. kuchotsedwa m'matanthwe a sedimentary, monga momwe zimakhalira ndi zotsalira zakufa.
Zotsatirazi ndi gawo la kalata yomwe inatumizidwa ndi S. Kasatkin (yotembenuzidwa kuchokera ku Chiyukireniya) poyankha nkhani yake yowona chithunzi chodabwitsa cha gudumu chomwe chinapezedwa ndi gulu lake la ogwira ntchito ku migodi mu 2008 - sanakhutire ndi vuto laling'ono lomwe linapangidwa likugwirizana ndi kupeza:
"Kupeza uku sikulumikizana ndi anthu. Patapita nthawi (2008) ife monga gulu la akatswiri ndi ogwira ntchito tinapempha mkulu wa mgodi kuitana asayansi kuti afufuze mwatsatanetsatane chinthucho, koma wotsogolera, potsatira malangizo a mwiniwake wa mgodiwo, analetsa kukambirana koteroko ndipo m'malo mwake, kokha. adalamulidwa kuti afulumizitse ntchitoyi (…) "
"Ndimalumikizana ndi anthu omwe adapeza koyamba zolemba izi komanso omwe adazijambula. Tili ndi mboni zoposa khumi ndi ziwiri. Monga mukumvetsetsa, kulowa mumgodi ndikochepa ndipo kupeza laisensi yotere ndikovuta komanso kovuta. ”
“Gulolo linasindikizidwa mu sandstone (…). Ena anayesa kudula zopezazo ndi nyundo (zosankhira) ndi kuzibweretsa bwino pamwamba, koma mwala wa mchengawo unali wamphamvu kwambiri (wolimba) mwakuti, poopa kuwononga chosindikiziracho, anausiya m’malo mwake. Pakalipano, mgodi watsekedwa (mwalamulo kuyambira 2009) ndipo kupeza chinthucho sikutheka - zida zatha ndipo zigawozo zasefukira kale. "
Ndi mawu okhawo olembedwa ndi a mboni zina, zithunzizo zimakhalabe umboni wofunikira wa chizindikiro chachikale chodabwitsachi, koma ziyenera kuonedwa kuti n’zoyenera kutchulidwa mosasamala kanthu za zovuta zilizonse pakutsimikizira tsatanetsatane wa mgodiwo.
Kuphatikiza apo, malinga ndi Kosatkin, ogwira ntchito m'migodi adavumbulutsa chithunzi china cha gudumu mozungulira nthawi yomweyo komanso mumsewu womwewo; komabe, iyi inali yaying'ono kwambiri kukula kwake.
Chifukwa chake, ngati umboni wazithunzi ulidi wovomerezeka (monga umboni wonse ukulongosolera), ndiye kuti munthu ayenera kudabwa kuti gudumu lopangidwa mochita kupanga lidalowetsedwa bwanji mu zigawo zakale zotere, pomwe, malinga ndi mbiri yakale, chitukuko china chapamwamba monga zathu sizinasinthe.
