Uburyo bwo Gutekereza ku Buhanga
1. Ishingiro ryo Kuramba
Kwizerwa ni ingenzi cyane mu bucukuzi bw'amabuye y'agaciro bwa longwall, aho gutsindwa kwa AFC ari byo bintu bikomeye bituma habaho ihagarara ry'akazi ritateganijwe, bikaba binatuma umusaruro uhagarara hafi 27% by'ihagarara ry'umusaruro wose. Ingorane nyamukuru y'iki kibazo ishingiye ku guhitamo umuyoboro ukwiye wo gukoreshwa. Imiyoboro ikora mu gihe cy'imizigo ikabije, kwangirika cyane, no kwangirika, bigatuma kuramba biba ingenzi mu miterere, ibikoresho, n'aho imikorere ibera. Iyi nyandiko isesengura imiterere y'ubudahangarwa bw'ubwoko bw'imiyoboro minini kugira ngo ifashe mu gufata ibyemezo byiza byo gutanga amasoko n'imikorere.
Iminyururu yo gucukura amakara ya longwallzikoreshwa muri Armored Face Conveyors (AFCs). Uko inganda zigenda zitera imbere, uburyo gakondourunigi rw'uruziga (DIN 22252)yateye imbere kugira ngo isimburwe ahanini n'izindi nzira zigezweho nkaiminyururu y'urukiramende (DIN 22255)n'imiterere igezweho ya "Ultra-Flat" cyangwa "Solid Profile". Bitandukanye mu buryo bwo gutsindwa, ibipimo by'imikorere, n'igihe cyose cy'ubuzima, bityo bikaba ingenzi mu guhitamo neza imiyoboro mu bikorwa bikomeye byo mu nkuta ndende.
2. Kugereranya imiterere y'uruhererekane: Imiterere ya Jewometiri n'uburyo bwo gutsindwa
Imiterere y'ibanze y'umunyururu igena mu buryo butaziguye uko ukwirakwira mu mihangayiko, imiterere yo kwangirika, n'uburyo bwo gucika intege kw'ibanze. Imbonerahamwe iri hepfo igaragaza muri make imiterere y'ingenzi:
| Igipimo cy'igishushanyo | Urusobe rw'ibice bikikije (DIN 22252) | Umuyoboro usanzwe w'urukiramende rufunganye (DIN 22255) | Urunigi rw'imiterere ihanitse / ikomeye |
| Ihame ry'ibanze | DIN 22252 | DIN 22255 | Ibishushanyo mbonera by'umutungo (urugero, "Umurongo Mukuru") |
| Imbaraga z'ingenzi zo Kuramba | Imiterere ingana kandi yoroshye; ikomeye cyane mu kwihanganira ingaruka. | Uburebure buri hasi muri rusange butuma imiterere y'ipaki igabanuka kandi ubushobozi bwo kuyitwara bwiyongera. | Ubuso bunini butuma igice cy'inyuma kigabanuka cyane, kandi imiterere y'inyuma irinda gufungana. |
| Intege nke z'ingenzi zo kuramba | Agace gato k'aho umuntu ahurira gatera stress nyinshi cyane ku buryo umuntu yakwangirika. | Imihangayiko yibanda ku bitugu byo mu matwi no ku menyo yo guhuza; ibyuma bihuza ni intege nke zikomeye. | Ubuhanga bwinshi mu gukora; bishobora gusaba uduce twihariye cyangwa ibice byabyo. |
| Uburyo bw'ibanze bwo kwambara/kwangirika | Kwangirika cyane ahantu hato hahurira abantu, bigatera gutakaza ibice birenga igice no "kwangirika no kunanirwa". | Umunaniro utangira ahantu hafite stress nyinshi (connectors, beginnings) munsi y'umutwaro uhoraho. | Kugabanya kwangirika muri rusange; byagenewe kugabanya uburyaryate n'uburebure bw'inyuma. |
3. Ibintu biramba birenze igishushanyo mbonera cy'ibanze
Kuramba ntibigaragazwa gusa n'imiterere y'aho ibintu bihurira. Hari ibintu byinshi bifitanye isano bigira uruhare runini:
- Ubumenyi bw'Ibikoresho n'Ubuhanga mu by'Ibyuma: Iterambere mu guteranya ibintu (Cr, Ni, Mn, Mo) no gutunganya neza ubushyuhe (kuzimya no gushyushya) bishobora kongera ubushobozi bwo kudashira ku kigero cya 10-25%. Ibyuma byiza nka 23MnNiCrMo54 bikoreshwa kugira ngo bigere ku buremere bwiza bwo kumena no kumara igihe kinini umuntu ananiwe.
- Kwizerwa kwa Connector: Kuri sisitemu z'amahuza agororotse, connector akenshi iba ari yo connector idakomeye. Gukoresha neza imiterere y'amenyo y'amahuza kugira ngo akwirakwizwe neza ni ingenzi cyane ku buzima bwa sisitemu muri rusange.
- Kurinda ingese: Ingese yihutisha kwangirika no kunanirwa. Imyambaro yo kurinda igezweho, nka zinc-nickel plating, ishobora kongera igihe ikagera kuri ibara ry'umutuku inshuro nyinshi ugereranije n'iy'umwimerere, bigatuma ubuzima bw'urunigi burushaho kuba bwiza mu gihe cy'ubukonje.
- Imyitozo ngororamubiri: Guhagarika neza umuvuduko ni ingenzi cyane. Guhagarika umuvuduko muto bitera gucika intege no gukomeretsa, mu gihe gukaza umuvuduko mwinshi byihutisha cyane kwangirika no kunanirwa. Gusuzuma buri gihe imigozi na byo ni ingenzi, kuko imigozi yashaje yangiza urunigi imburagihe.
4. Uburyo bwo guhitamo: Guhuza uruhererekane n'ikoreshwa
Nta ruhererekane "rutunganye" rubaho ku isi hose, ariko hari uruhererekane rwiza rujyanye n'ibihe runaka. Guhitamo bigomba kuba inzira y'ubufatanye hagati y'ikirombe n'ugikora.
- HitamoIminyururu y'uruziga (DIN 22252)igihe: Icy'ingenzi ni ubworoherane bwinshi no gufata ingaruka mu gihe cy'imigozi igoye kandi idahuje. Imiterere yazo irahagije mu gihe hashobora kubaho kugorana cyangwa kugorama.
- Hitamo IbisanzweIminyururu y'urukiramende (DIN 22255)igihe: Hari uburebure bw'imodoka zitwara imizigo, kandi hakenewe imiterere y'imashini yo hasi kugira ngo hongerwe ubushobozi. Ni uburyo bwo kongera ubushobozi bwazo mu buryo butaziguye ku buryo bwo guhuza imizigo butagira impinduka zikomeye ku murongo w'imashini zitwara imizigo.
- Hitamo imiyoboro ya "Ultra-Flat" cyangwa "Solid Profile" igezweho iyo: Intego y'imikorere ni ukongera igihe cyo gukora no kugabanya igihe cyo kudakora mu miyoboro ifite imbaraga nyinshi kandi itwara toni nyinshi. Imiterere yayo yakozwe neza igamije gukemura mu buryo butaziguye impamvu zitera kwangirika no kwangirika kw'imiyoboro.
5. Umwanzuro
Impinduka kuva ku miterere y’uruziga kugeza ku miterere igezweho y’uruziga igaragaza impinduka kuva ku gukomera rusange kugera ku mikorere myiza yo kwambara. Nubwo imiyoboro izunguruka itanga ubushobozi bworoshye, imiyoboro irambuye n’irambuye cyane itanga ibisubizo byabugenewe byo kongera ubushobozi no kuramba. Amahitamo arambye cyane ni icyemezo cyo ku rwego rwa sisitemu kireba imiterere, ubwiza bw’ibikoresho, imiterere y’ibihuza, kurangiza neza ibikorwa, ndetse no—mu buryo bw’ingenzi—kubungabunga imikorere. Amaherezo, gushora imari mu muyoboro "ujyanye neza n’imimerere runaka" kandi ugashyigikirwa n’ubufatanye bw’abahanga mu bya tekiniki ni yo ngamba nziza cyane yo kongera igihe cyo gukora no gutanga umusaruro.
