I ke kaʻina hana o nā mines lanahu, aia nā mea pahū e like me ke kinoea a me ka lepo lanahu. I mea e hōʻoia ai i ka hana palekana a pale i nā pōʻino pahū i hoʻokumu ʻia e ke kinoea a me ka lepo lanahu, ma ka ʻaoʻao hoʻokahi, pono e hoʻomalu ʻia ka ʻike o ke kinoea a me ka lepo lanahu i ka lewa ma lalo o ka honua; ma ka ʻaoʻao ʻē aʻe, pono e hoʻopau ʻia nā kumu hoʻoheheʻe a me nā kumu wela wela nui e hiki ke hoʻā i ke kinoea a me ka lepo lanahu i loko o nā mines.
Ua māhele ʻia nā lako uila koʻu i ʻelua ʻāpana, ʻo ia hoʻi nā lako uila maʻamau a me nā lako uila hōʻike ʻole i ka pahū.
ʻO kaʻu mau mea uila maʻamau he mea pahū ʻole i hoʻohana ʻia i loko o nā lua lanahu. Hiki ke hoʻohana wale ʻia ma nā wahi ʻaʻohe pilikia o ke kinoea a me ka pahū lepo lanahu ma lalo o ka honua. ʻO nā koi kumu no ia: ikaika a paʻa ka pūpū, hiki ke pale i ka hoʻopili pololei ʻana me nā ʻāpana ola mai waho; he maikaʻi ka kulu, splash a me ka moisture-proof hana; aia kahi mea hoʻokomo kelepona, a hiki iā ia ke pale i ke kaula mai ka wili, huki a me ka pōʻino; aia kahi mea paʻa ma waena o ka mea hoʻololi a me ka uhi puka, etc.
- . Nā ʻano mea pahū-pale uila no ka ʻeli ʻana
Wahi a nā koi pahū like ʻole, ua māhele nui ʻia nā mea uila pahū no ka mining i ke ʻano explosion-proof no ka mining, hoʻonui i ke ʻano palekana no ka mining, ʻano palekana intrinsic no ka mining, ʻano kaomi maikaʻi no ka mining, ʻano hoʻopiha one no ka mining, cast-in-place type no ka mining a me ke ʻano paʻa kinoea no ka mining.
- ʻO nā lako uila pahū no ka ʻeli ʻana
ʻO ka mea i kapa ʻia ʻo explosion-proof, ʻo ia ka hoʻokomo ʻana i nā ʻāpana ola o nā mea uila i loko o kahi pūpū kūikawā. ʻO ka pūpū ka hana o ka hoʻokaʻawale ʻana i nā ʻālohilohi a me nā arcs i hana ʻia e nā ʻāpana uila i loko o ka pūpū mai ka hui pahū ma waho o ka pūpū, a hiki ke kū i ke kaomi pahū i hana ʻia i ka wā e hoʻopau ʻia ai ka hui ʻana o ka pahū i loko o ka pūpū e nā ʻulaʻula a me nā arcs o nā mea uila i loko o ka pūpū, ʻoiai ʻaʻole i luku ʻia ka pūpū, a i ka manawa like, hiki iā ia ke pale i ka pahū ʻana o ka pūpū. Kapa ʻia kēia pūpū kūikawā he pūpū pale ahi. Ua kapa ʻia nā mea uila me ka pūpū ʻaʻa ahi he mea uila pale ahi.
- Hoʻonui i nā lako uila palekana no ka ʻeli ʻana
ʻO ke kumu pahū-hōʻoia o ka hoʻonui ʻana i nā lako uila palekana ʻo ia: no kēlā mau mīkini uila e hoʻohua ʻole i nā arcs, nā ʻulaʻula a me nā mahana pōʻino ma lalo o nā kūlana hana maʻamau, i mea e hoʻomaikaʻi ai i ko lākou palekana, lawe ʻia nā ʻano hana i loko o ke ʻano, ka hana hana a me nā kūlana ʻenehana o nā mea hana, i mea e pale ai i nā mea hana mai ka hana ʻana i nā huna ahi, nā arcs a me nā mahana pōʻino ma lalo o ka hana a me nā kūlana overloading, a hoʻokō i ka pahū uila. ʻO ka hoʻonui ʻana i nā lako uila palekana e hana i kekahi mau hana e hoʻomaikaʻi ai i kona pae palekana e pili ana i nā kūlana ʻenehana mua o nā mea uila, akā ʻaʻole ia he manaʻo ʻoi aku ka maikaʻi o kēia ʻano mea uila ma mua o nā ʻano mea uila ʻē aʻe. ʻO ke kiʻekiʻe o ka hana palekana o ka hoʻonui ʻana i nā lako uila palekana ʻaʻole i hilinaʻi wale i ke ʻano o ke ʻano o ka lako ponoʻī, akā i ka mālama ʻana i ke ʻano o ka hoʻohana ʻana i nā mea hana. ʻO kēlā mau mea uila wale nō e hoʻoulu ʻole i nā arcs, nā ʻulaʻula a me ka wela nui i ka wā o ka hana maʻamau, e like me nā transformers, motors, nā kukui uila, a me nā mea ʻē aʻe, hiki ke hoʻonui ʻia i nā lako uila palekana.
- ʻO nā lako uila palekana maoli no ka ʻeli ʻana
ʻO ka manaʻo pahū o nā lako uila palekana maoli ʻo ia: ma ka hoʻopaʻa ʻana i nā ʻāpana like ʻole o ke kaapuni uila, a i ʻole ka lawe ʻana i nā hana pale e kaupalena i ka ikehu hoʻokuʻu ʻana a me ka ikehu wela o ke kaʻapuni, nā ʻōhū uila a me nā hopena wela i hana ʻia i ka hana maʻamau a me nā kūlana hewa i ʻōlelo ʻia ʻaʻole hiki ke hoʻā i ka hui pahū i ke kaiapuni a puni. ʻO ke kaʻapuni o kēia ʻano mea uila ponoʻī he hana pahū, ʻo ia hoʻi, "ʻoiaʻiʻo" palekana, no laila ua kapa ʻia ʻo ia ka palekana intrinsically (ma hope aku i kapa ʻia he intrinsically safe). Ua kapa ʻia nā mea uila e hoʻohana ana i nā kaapuni palekana intrinsically.
- ʻO nā lako uila puʻe maikaʻi
ʻO ke kumumanaʻo pahū-hōʻoia o nā mea uila puʻupuʻu maikaʻi: ua kau ʻia nā mea uila i loko o ka pūpū o waho, ʻaʻohe kumu o ka hoʻokuʻu ʻana i ke kinoea lapalapa i loko o ka pūpū; piha ka pūpū i ke kinoea pale, a ʻoi aku ke kiʻekiʻe o ke kaomi o ke kinoea pale i loko o ka pūpū ma mua o ke kaomi ʻana o ke kaiapuni pahū a puni, i mea e pale ai i ka hui ʻana o waho mai ke komo ʻana i ka pūpū a ʻike i ka pahū-hōʻoia o nā lako uila.
ʻO ka hōʻailona o nā mea uila puʻe maikaʻi ʻo "p", a ʻo ka inoa piha o ka hōʻailona ʻo "Expl".
- ʻO nā lako uila piha i ke one no ka ʻeli ʻana
ʻO ke kumu pahū o nā lako uila i hoʻopiha ʻia i ke one: e hoʻopiha i ka ʻili o waho o nā mea uila me ke one quartz, e kanu i nā ʻāpana conductive a i ʻole nā wahi ola o nā mea hana ma lalo o ka quartz sand explosion-proof filler layer, no laila ma lalo o nā kūlana i kuhikuhi ʻia, ka arc i hana ʻia i loko o ka pūpū, ka lapalapa i hoʻolaha ʻia, ka wela wela o ka pā o waho a i ʻole ke one a puni ka mea hiki ʻole ke pahū.
