Te rerekētanga i waenga i te para parahi me te onepu karaka mō te pupuhi onepu

1. Ngā āhuatanga ā-roto o te onepu karāneti me te para parahi

Oneone karakahe mea whakakoi taiao, he mea hanga te nuinga mai i ngā silicates.Para parahihe toenga o te whakarewa parahi, he iti te utu, engari kāore i te tino teitei tōna pakeke. Ko ngā matū whakarewa kei roto ipara parahiHe taumaha rawa, ā, ka uru pea ētahi matūriki ki roto i te papa, ka waikura ai. Engari hei mea whakakoi, he koi ngā taha o ēnei katoa, ā, ko te onepu karāneti he hanganga taimana, he 12 ngā taha. I te wā e pupuhi ana i te onepu, ka taea te whakamahi i ngā taha koi ake hei tapahi i ngā paru mai i te papa, kia pai ake ai te hua.

2. Te whakataurite i te pānga o te onepu karāneti mepara parahingā mea whakakoi onepu

Para parahiHe tino teitei te ōwehenga puehu i te wā e pupuhi ana te onepu, ā, he ngoikore te taiao pupuhi onepu. Heoi anō, kāore i te tino teitei te pānga o te pupuhi onepu, nō reira he iti noa te maimoatanga taratara ka taea te mahi.Oneone karakakua oti i a ia te wehe i ngā aukume e 3, ngā tātari e 4, ngā horoinga wai e 6, me ngā huringa whakamaroke e 4, he painga tōna ki te ma, ā, ka taea te tango katoa i ngā poke i runga i te mata o te papa, ka tutuki ai te pānga pupuhi onepu o te SA3. Nō reira, i runga i te whai huatanga, he pai ake te onepu karaka i tepara parahi.Te rōrahi me te papatipu opara parahiHe nui ngā matūriki (hei tauira, ko te hua 30/60 #, e 1.3 miriona ngā matūriki mō ia kirokaramu o te para parahi, ko te onepu karāneti ia he 11 miriona ngā matūriki), nō reira ko te tere o te para parahipupuhi onepuHe puhoi te horoi, ā, me nui ake te para parahi e pau ana mō ia wāhanga horahanga.

3. Te whakataurite utu o ngā mea whakakoi kirikiri

Ki te whakataurite kite para parahi,He nui ake te utu o te onepu karāneti, engari mō te whakamahinga anō, nā te pakeketanga, ka taea te whakamahi anō i te onepu karāneti neke atu i te 3 ngā wā, ā, he iti ake te utu mō te whakamahinga kotahi i ērā atu mea whakakoi.Para parahihe iti ake te utu, engari he puhoi te tere o te pupuhi onepu, ā, ko te utu e pau ana i te onepu mō ia mita tapawha he 30-40% teitei ake i te onepu karaka.

4. Te Whakataurite i ngā Mea Whakakoi Oneone kiOneone KarakamePara Parahi- Te Tiakitanga Kakariki me te Taiao

Para parahiHe nui te puehu, ā, he iti te matotoru o ētahi matū kei roto, ka puta ai he puehu ki te mata mahi. He nui hoki te puehu i runga i te mata onepū, me horoi tuarua.Para parahikei roto ngā matū kino, ā, mā te whakamahinga roa ka pā mai ngā mate mahi kāore e taea te whakahaere mā ngā kaimahi - te silicosis. Kāore he otinga pai i tēnei wā.

Oneone karakaHe nui te ōwehenga, ā, tata kore he puehu i roto i ngā hua kounga teitei. Ehara i te mea kāore he matū kino i roto, engari kāore hoki he puehu whānui i te wā o te pupuhi onepu, ka tino whakapai ake i te taiao pupuhi onepu. Ā, ka taea te whakamahi anō, ka waiho hei ōhanga pai ake mō te taiao i raro i te whakatairanga a te whenua i te ōhanga matomato.
