Pambuyo pomaliza ntchitoyi, Yu XX, double XX adaganiza zoyesa kupanga popanda chilolezo.

M'mawa kwambiri pa Ogasiti 10, 2016, ogwira ntchito ku malo ochitira boiler a B Gangue Power Generation Company omwe anali pantchito adapeza kuti pansi yakutsogolo kwa chipinda chowongolera chapakati panali kudontha madzi ndipo gawo loteteza la payipi yayikulu ya nthunzi ya No. 2 Boiler linali kudontha nthunzi panthawi yowunikira. Zhao Yu, Wang Mou anathamangira pamalopo, sanapeze momwe madzi anali kudontha komanso malo otayikira, palibe kufufuza kwina. Pa 11 koloko pa Ogasiti 11, woyendetsa boiler adapeza kudontha pafupi ndi nozzle ya ngozi ndipo kutentha kunali kwakukulu kuposa masiku onse, Zhao Yu adalangiza ogwira ntchito omwe anali pantchito kuti apitirize kulimbikitsa kuyang'anira. Pafupifupi 13 koloko, kudontha kwa nthunzi kuchokera ku payipi yayikulu ya nthunzi ya No. 2 kunali kowonekera bwino komanso kutsagana ndi phokoso la pafupipafupi. Zhao Yu, Wang Moumou sanatero malinga ndi "Boiler Safety Technical Regulations" "Boiler Operation Regulations" ndi zina mwa malangizo otseka mwadzidzidzi. Kuyambira 13:50 mpaka 14:20, Ye adalandira mafoni atatu kuchokera kwa wachiwiri kwa mkulu wa Production Division of B Stone Power Generation. Kampani ndi wotumiza wa Production Dispatch Center of A Chemical Group, akunena kuti "pali kutayikira mu payipi yayikulu ya nthunzi ya No. 2 Boiler, ndipo tikupempha kuti tiyimitse boiler". Musapite kukataya malo ochitira ngozi, kapena malinga ndi zomwe zili mu lamulo loti tiyimitse ng'anjo. Nthawi ya 14:30, Ye X adauza Zhao X kuti "kutayikira kwa payipi ya nthunzi, chomera chamagetsi chikufunika kuti tiyimitse ng'anjo". Zhao Mou ena sanatero malinga ndi zomwe zili mu lamulo loti tiyimitse ng'anjo, komanso sanapite kukataya malo ochitira ngozi. Nthawi ya 14:49, ma nozzles pa payipi yayikulu ya nthunzi yamphamvu ya boiler yachiwiri idaphulika, zomwe zidapangitsa kuti nthunzi yambiri yotentha ifalikire m'dera la ngozi, zomwe zidapangitsa kuti anthu 22 afe, 4 avulala, komanso kutayika kwachuma kwa 23.13 miliyoni yuan.

Kuwunika momwe ntchito zawo zimagwirira ntchito

Pambuyo pa ngoziyi, ofesi ya chitetezo cha anthu mumzinda wa Yang, poganizira kuti ndi mlandu waukulu wa ngozi womwe unachitikira Yu, Zhang, Zhao, Wang, Zhao, Ye ndi anthu ena omwe akufufuzidwa, inachitapo kanthu mokakamiza. People's Procuratorate of Yangyang City inalowererapo pasadakhale ndipo inatenga nawo mbali pa kafukufuku wa milandu ya mabungwe achitetezo cha anthu. Mfundo zazikulu zosonkhanitsira umboni zinaperekedwa kuchokera ku mbali zitatu: choyamba, chinali kupeza ngati makampani a ngozi anaswa malamulo ndi malangizo povomereza polojekiti, kugula zida, kumanga polojekiti ndi kupereka ma bidding; Chachiwiri ndikupeza udindo wa Yu ndi ena pakupanga chitetezo cha makampani; Chachitatu ndikupeza momwe Yu ndi anthu ena amagwirira ntchito komanso khalidwe lawo. Pamene Dipatimenti ya Chitetezo cha Anthu ku Yangyang inawonjezera ndikuwongolera umboni womwe uli pamwambapa, kafukufukuyo atatha, anthu 7 kuphatikizapo Yu XX ndi ena adasamutsidwira ku People's Procuratorate of Yangyang kuti akaimbidwe mlandu pa Januware 23, 2017 komanso pa February 22, 2017.

Pa Ogasiti 21, 2018, Khothi la Anthu ku Dangyang City linagamula kuti otsutsa Yu, Shuang ndi Zhang akhale m'ndende kwa zaka zisanu, zinayi, ndi zisanu motsatana chifukwa cha mlandu wokhudza ngozi zoopsa pantchito. Zhao anaweruzidwa kuti akhale m'ndende kwa miyezi inayi ndi isanu ndi umodzi chifukwa cha mlandu wokhudza ngozi zazikulu komanso mlandu wothandiza kuwononga umboni, ndipo anaganiza zotumikira miyezi inayi ndi itatu pa milandu ingapo. Ndi mlandu wokhudza ngozi zazikulu motsatana, wotsutsa Ye, Zhao Yu, Wang Mou anaweruzidwa kuti akhale m'ndende kwa zaka zinayi, zisanu, ndi zinayi. Palibe wotsutsa amene anapempha ndipo zigamulozo zinayamba kugwira ntchito.
