Amakuru - Gutsinda Igihe cyo Kudakora: Gukemura Guhuza no Gutunganya Imiyoboro ya Longwall

Ku bikorwa bya longiwall, igihe cyo kudakora neza kw'imodoka (conveyor) kitunguranye ni umwanzi w'umusaruro. Nubwo gutsindwa bishobora gusa n'ibitunguranye, akenshi biterwa n'ibibazo bya tekiniki bishobora kwirindwa. Ibintu bibiri by'ingenzi bigomba kwitabwaho ni ikibazo gihoraho cyo "gukora ku rushundura" n'uburyo bw'ibanze bwo kubungabunga urushundura. Kubyumva no kubikemura bishobora kunoza cyane uburyo umucuruzi wawe ahora yizewe kandi akamara igihe kirekire.

Ikibazo cy'urunigi "Knuckling"

Uburyo bwihariye kandi bwangiza imikorere y’imodoka zitwara imizigo mu nkuta zizwi nka "knuckling." Ibi bibaho iyo umurongo uzengurutse w’umuyoboro w’imodoka uzenguruka uhagaze, uhagaze kuri dogere 90 ugana ku murongo usanzwe ugororotse. Iyo umaze kugera kuri uyu mwanya uhagaze, umurongo ushobora kugwa imbere y’umurongo w’indege (scraper). Ibi bituma umurongo uhagarara neza ku gice cy’umuhanda, bikawubuza gusubira inyuma mu cyerekezo cyawo gikwiye no gutuma sisitemu ifunga burundu.

Ingaruka ni uguhagarara ako kanya, ku buryo bishobora kwangiza cyane umunyururu, imigozi yo mu kirere, n'udupira two mu kirere. Kugira ngo bikemurwe bisaba ubufasha bukomeye bw'intoki, bigatera igihe kirekire cyo kuruhuka.

Umuti w'Ubwubatsi: Ibyuma Birwanya Ingufu

Umuti w'iki kibazo ni igishushanyo mbonera cyoroheje kandi gikomeye cy'ubuhanga: icyinjizwa kidakoresha amagufwa. Nk'uko bigaragazwa mu nyandiko z'ubucukuzi bw'amabuye y'agaciro, iki gikoresho ni icyinjizwa cya polymer cyagenewe kwinjira mu gace k'imbere k'uruhererekane rw'umunyururu.

Yakozwe mu bushyuhe bukomeye kandi burambye, igice cyo hejuru gipima ubugari burenze gato uburebure bw'imbere bw'igice cyo hejuru. Mu gihe cyo gushyiraho, gishyirwa hagati y'impande zifatanye z'igice cyo hejuru. Iyo kimaze gushyirwaho, gisubira mu ishusho yacyo ya mbere, cyifungirana neza ku nkuta z'imbere z'igice cyo hejuru. Kugira ngo habeho umutekano wimbitse, agapira gafunga gakunze kunyuzwa mu gice cyo hejuru kugira ngo kadasenyuka bitewe n'imitwaro ikabije.

Mu kuzuza umwanya uri mu gice cy'urukiramende, icyo gice cy'urukiramende kibuza uruhererekane kuzenguruka mu mwanya uhagaze "ufite amagufwa", bityo bigakuraho impamvu nyamukuru y'urukiramende.

Gukomeza Kwirinda: Uburyo Bwawe bwa Mbere bwo Kwirinda

Nubwo ibisubizo nk'ibice birwanya imigozi bikemura ibibazo runaka, uburyo bukomeye bwo kubungabunga ibidukikije ni inkingi ikomeye y'ubuzima bw'imiyoboro y'amashanyarazi ya longwall. Ubushakashatsi bw'inganda bwagaragaje ko ijanisha rinini ry'igihe cyo kudakora neza kw'imigozi—bingana na 27% mu birombe mu bushakashatsi bumwe bunini—bifitanye isano no kudakora neza kw'imigozi, aho umuvuduko utari wo w'imigozi ari wo utera imbere.

Dore inkingi z'ingenzi z'ingamba zo kubungabunga neza indwara:

1. Umuvuduko w'umuyoboro w'ikirenga n'uburemere

Umuvuduko ukwiye w'umunyururu ushobora kuba ari wo kintu cy'ingenzi cyane mu kubungabunga. Umuvuduko ukabije ni yo mpamvu nyamukuru yangiza, ituma umunyururu wiyongera, uduce duto dusimbuka, kandi tugatembagara. Ku rundi ruhande, umunyururu ufunganye cyane wihutisha kwangirika kw'imirongo no kwangirika kw'imirongo. Intego ni ugukomeza umuvuduko ubanziriza umuvuduko ubuza umuvuduko gutinda ku mutwaro udatera umuvuduko ukabije. Pima buri gihe kandi uhindure umuvuduko ukoresheje icyuma gipima umuvuduko, kandi ukureho umunyururu uto ugenzurwa (urugero, uduce tubiri icyarimwe).

2. Gukurikirana no gupima uburebure bw'urunigi

Umunyururu ntabwo "ugenda" mu by'ukuri; uragenda urekura bitewe n'uko iminyururu yangiritse aho ihurira. Gukurikirana ubu burebure ni uburyo butaziguye bwo gupima ubuzima bw'umunyururu n'ubuzima busigaye. Koresha caliper y'umunyururu kugira ngo upime buri gihe uburebure bw'umunyururu bugenwe. Nk'amabwiriza rusange, iminyururu ishobora gutekerezwaho gusimburwa iyo uburebure burenze 3%, nubwo ibikorwa byinshi bishyiraho umupaka uhoraho wa 2%.

3. Shyira mu bikorwa gahunda yo kugenzura ikorwa mu buryo bwimbitse

Isuzuma rikorwa ku buryo buteganyijwe rishobora gufata ibibazo bito mbere yuko birushaho kwiyongera. Urutonde rwawe rugomba kuba rurimo:

- Udupira: Reba niba amenyo yashaje, yacitse, cyangwa yaciwe. Udupira twashaje twihutisha kwangirika kw'umunyururu kandi dushobora gutuma amenyo afatwa nabi.

- Guhuza: Menya neza ko uduce duto, udusanduku two koherezamo ibintu, n'umurongo wose w'isura bihuye neza. Umurongo mubi w'isura utuma habaho guhagarara nabi no kwangirika gutandukanye hagati y'imigozi y'urunigi.

- Imiterere n'Imiterere: Fata uduti twose tw'ihuza n'imigozi, hanyuma usimbuze imigozi idafite aho ihurira n'isafuriya. Reba amasafuriya yangiritse cyangwa uduce twangiritse dushobora kuyobya umugozi.

4. Shyira mu bikorwa politiki yo gusimbuza ibintu mu buryo bwihuse

Ntugakoreshe ibice kugeza igihe byananiranye. Shyiraho ibipimo bisobanutse kandi bishingiye ku makuru byo gusimbuza imiyoboro y'uruhererekane n'imiyoboro y'uruhererekane hashingiwe ku bipimo by'uburebure n'ubusaza bw'imiyoboro y'uruhererekane. Gukoresha imiyoboro y'uruhererekane yashaje cyane hamwe n'imiyoboro mishya (cyangwa se ibinyuranye n'ibyo) bitera kwangirika vuba kandi vuba kuri byombi.

Mu guhuza ibisubizo by’ubuhanga byihariye ku buryo buzwi bwo gutsindwa nko gukubita no kubungabunga ibintu mu buryo bwizewe kandi bushingiye ku makuru, ibikorwa bishobora guhindura uburyo bwo gutwara ibintu mu nkuta ndende buva ku isoko ry’igihe cyo kudakora ibintu mu nkuta ndende bukaba inkingi y’umusaruro utegerejwe kandi utangwa n’abantu benshi.
