Incamake
Muburyo bwo gukuramo kabiri bizwi nkubucukuzi burebure buringaniye buringaniye buringaniye (mubisanzwe uri hagati ya 100 na 300m ariko birashobora kuba birebire) bikozwe mugutwara umuhanda kumurongo ugororotse hagati yinzira ebyiri zigize impande zumuhanda muremure, hamwe urubavu rumwe rwumuhanda mushya ukora isura ndende. Iyo ibikoresho birebire bimaze gushyirwaho, amakara arashobora gukururwa mu burebure bwuzuye bwo mumaso mu bice by'ubugari bwatanzwe (byitwa "urubuga" rw'amakara). Isura ndende ya kijyambere ishyigikiwe ninkunga zikoreshwa n’amazi kandi izo nkunga zigenda zambukiranya buhoro buhoro kugira ngo zishyigikire isura nshya yakuweho kuko ibice byafashwe, bituma igice cy’amakara cyari cyacukuwe mbere kigashyigikirwa gusenyuka (guhinduka ihene). Iyi nzira isubirwamo ubudahwema, urubuga kurubuga, bityo ukuraho burundu urukiramende rwurukiramende rwamakara, uburebure bwahagaritswe bitewe nibintu byinshi (reba inyandiko nyuma)
Sisitemu yo gutwara amakara yashyizwe mumaso, mumaso igezweho "umutwaro wo mumaso cyangwa AFC". Inzira nyabagendwa zigize impande zahagaritswe zitwa "umuhanda wamarembo". Umuhanda umuhanda wa convoyeur ushyizwemo witwa "irembo rikuru" (cyangwa "maingate"), umuhanda kumuhanda uteganye nawo witwa "irembo ryumurizo" (cyangwa "umurizo").
Ibyiza byo gucukura igihe kirekire ugereranije nubundi buryo bwo gukuramo inkingi ni:
• Inkunga zihoraho zirakenewe gusa mugice cyambere cyakazi no mugihe cyo kwishyiriraho no kugarura. Ibindi bisenge byo hejuru (ibisakuzo birebire cyangwa ingabo kumurongo muremure bigezweho) byimurwa kandi byimurwa hamwe nibikoresho byo mumaso.
• Kugarura umutungo ni mwinshi cyane - mubitekerezo 100% byahagaritswe amakara, nubwo mubikorwa harigihe habaho gusuka amakara cyangwa kumeneka muri sisitemu yo gutwara mumaso yatakaye muri goaf, cyane cyane niba hari amazi menshi kuri mu maso
Sisitemu yo gucukura Longwall irashobora gutanga umusaruro ushimishije mumaso imwe ndende - toni miliyoni 8 kumwaka cyangwa zirenga.
• Iyo ikora neza amakara acukurwa muburyo butunganijwe, burikomeza kandi busubiramo nibyiza mugucunga ibice no mubikorwa byubucukuzi bifitanye isano
• Amafaranga yumurimo / toni yakozwe ni make
Ibibi ni:
• Hariho igishoro kinini cyibikoresho, nubwo birashoboka ko bitari hejuru nkuko bigaragara bwa mbere mugihe ugereranije numubare wibice bikomeza gucukurwa byasabwa kubyara umusaruro umwe.
• Ibikorwa byibanda cyane ("amagi yose mugiseke kimwe")
• Inzira ndende ntishobora guhinduka cyane kandi "ntishobora kubabarira" - ntabwo ikora neza guhagarika ingendo; imihanda yo mumarembo igomba gutwarwa murwego rwo hejuru cyangwa ibibazo bizavuka; isura nziza yo mumaso akenshi iterwa numusaruro uba mwinshi cyangwa mukomeza, bityo ibibazo bitera gutinda birashobora kwiyongera mubintu bikomeye.
• Kubera imiterere yo kutababarira kwinzira ndende, umurimo w'inararibonye ni ngombwa kugirango ibikorwa bigende neza.
Icyemezo gikomeye kigomba gufatwa nubunini bwa burebure ndende. Kuberako uburebure bugezweho burimo umubare munini wibikoresho (umubare wubunini bwibintu magana, hamwe nibice byinshi bipima toni 30 cyangwa zirenga), inzira yo kugarura ibikoresho mumwanya wuzuye, ukayijyana kumurongo mushya. hanyuma ukayishyira mubice bishya (akenshi hamwe nibyinshi bivanwa mu kirombe kugirango bivugururwe munzira) nigikorwa gikomeye. Usibye ikiguzi kiziguye kirimo, umusaruro bityo amafaranga yinjiza ni zeru muriki gihe. Inzira nini ndende izafasha umubare wimuka kugabanuka, icyakora hariho ibintu bigabanya ingano yuburebure burebure:
• Igihe kinini mumaso niko imbaraga zisabwa kuri sisitemu yo gutwara amakara yo mumaso (reba ibisobanuro nyuma kuri AFC). Nimbaraga nini, nini nini yumubiri wibice bya drayike (mubisanzwe hariho igice cyo gutwara ku mpande zombi zo mumaso). Ibice bigendesha ibinyabiziga bigomba guhura nubucukuzi kandi bikemerera umwanya wo kubigeraho, kugirango uhumeke neza mumaso ndetse no kurwego runaka hejuru yinzu kugeza gufunga hasi. Na none imbaraga nini, nini (kandi rero ziremereye) theiminyururukuri convoyeur yo mu maso - iyi minyururu ihuza ibyuma igomba guhindurwa mu maso rimwe na rimwe kandi hari imbogamizi zifatika zijyanye n'ubunini bw'iminyururu.
• Mubice bimwe birebire, ubushyuhe buterwa nimbaraga nini zo gutwara ibintu bishobora kuba ikintu.
• Ubugari bwombi bwuburebure nuburebure bushobora kugengwa nimbogamizi zashyizweho nimbibi zubukode, guhagarika ingendo cyangwa gutandukana, bimaze guterwa amabuye y'agaciro hamwe na / cyangwa ubushobozi bwo guhumeka.
• Ubushobozi bwikirombe bwo guteza imbere imirongo miremire miremire kugirango ubudahangarwa bwigihe kirekire butagira ingaruka mbi.
• Imiterere yibikoresho - guhindura ibintu bimwe na bimwe byo kuvugurura cyangwa gusimburwa mugihe cyubuzima bwumwanya muremure birashobora kuba ikibazo, kandi nibyiza gukorwa mugihe cyo kwimuka.
