Emva kokugqitywa kweprojekthi, uYu XX, double XX wagqiba ekubeni azame ukuvelisa ngaphandle kwemvume.

Ngentsasa yokuqala yomhla we-10 ku-Agasti 2016, abasebenzi be-boiler workshop ye-B Gangue Power Generation Company ababesemsebenzini bafumanise ukuba umgangatho ongaphambili wegumbi lolawulo eliphakathi wawuvuza amanzi kwaye umaleko wobushushu wombhobho ophambili womphunga ophantsi koxinzelelo oluphezulu we-No. 2 Boiler wawuvuza umphunga ngexesha lokuhlolwa. UZhao Yu, uWang Mou wakhawuleza waya kwindawo yesiganeko, akafumananga imeko yokuvuza kunye nendawo yokuvuza, akukho phando luqhubekayo. Ngentsimbi ye-11 ngomhla we-11 ku-Agasti, umqhubi we-boiler wafumana ukuvuza kufutshane nomlomo wengozi kwaye ubushushu babuphezulu kunesiqhelo, uZhao Yu wayalela abasebenzi ababesemsebenzini ukuba baqhubeke nokuqinisa ukubekwa esweni. Malunga nentsimbi ye-13, ukuvuza komphunga kwipayipi ophambili womphunga we-No. 2 boiler kwakubonakala ngakumbi kwaye kuhamba nengxolo ephezulu. UZhao Yu, uWang Moumou akazange ngokwe-"Boiler Safety Technical Regulations" "Boiler Operation Regulations" kunye neminye imiqathango yemiyalelo yokuvala ungxamiseko.

Inkampani kunye nomthumeli weZiko leMveliso yeDispatch leQela leeKhemikhali, bexela ukuba "kukho ukuvuza kumbhobho ophambili womphunga weNombolo 2 yeBoiler, kwaye sicela ukuba simise ibhoyila". Musa ukuya kwindawo yokulahla, okanye ngokwemimiselo yomyalelo wokumisa ifurnace. Nge-14:30, uYe X waxela kuZhao X "ukuvuza kombhobho womphunga, isityalo samandla esifunekayo ukuze simise ifurnace". Abanye uZhao Mou abazange ngokwemimiselo yomyalelo wokumisa ifurnace, nabo abazange baye kwindawo yokulahla. Nge-14:49, ii-nozzles kumbhobho ophambili womphunga ophantsi koxinzelelo oluphezulu webhoyila enguNombolo 2 zaqhuma, nto leyo eyabangela ukuba inani elikhulu lomphunga oshushu kakhulu utshize kwindawo yengozi, nto leyo eyabangela ukufa kwabantu abangama-22, ukwenzakala kwaba-4, ilahleko yezoqoqosho ethe ngqo ye-23.13 yezigidi zeeyuan.
