Shenhai Explosion-Proof
GB3836.1-2010 “Explosive Atmospheres Part 1: Cov khoom siv dav dav” cais cov khoom siv hluav taws xob tawg rau hauv ob hom tseem ceeb raws li lawv qhov chaw siv: Cov khoom siv hluav taws xob Class I thiab Class II.
Chav Kawm I Cov Khoom Siv Hluav Taws Xob
Hom no yog tsim tshwj xeeb rau kev siv nyob rau hauv ib puag ncig muaj feem xyuam rau underground thee mining thiab deg processing thee. Nws feem ntau yog hais txog cov khoom siv hluav taws xob ua haujlwm hauv thaj chaw uas muaj methane thiab thee hmoov av. Lub underground thee mining tsim ib puag ncig yog tsis muaj npe nrov nyuaj, characterized los ntawm lub xub ntiag ntawm nplaim taws gases zoo li methane, combustible plua plav zoo li coal tshauv, thiab ntxiv kev nyuaj siab xws li ya raws, av noo, thiab pwm. Cov xwm txheej no ua rau cov kev xav tau tshiab ntawm kev tsim qauv, kev tsim khoom, thiab siv cov khoom siv hluav taws xob.
Chav Kawm II Cov Khoom Siv Hluav Taws Xob
Cov khoom siv no haum rau tawg Gas ib puag ncig sab nraum cov thee mines thiab feem ntau xa mus rau cov khoom siv hluav taws xob ua haujlwm hauv qhov chaw (suav nrog ob qho tib si combustible gas thiab plua plav ib puag ncig).
