Vuba aha, KR90A izengurutsa imashini ya Tyhen fondasiyo yubatswe umushinga wo gushimangira uruganda rwa Luoyang, Intara ya Henan.Biravugwa ko geologiya isubira inyuma yamabuye na sili, gutura umusingi bizatera ibice kandi bigira ingaruka kumutekano wubwubatsi.Inzira ikorerwa kumurimo ikubiyemo kubanza gutaka kugirango yuzuze ibice no kuziba icyuho muri strata, hanyuma hakurikiraho gukoresha gucukura ibirundo birambiranye kugirango habeho umusingi wibanze kumiterere mishya, amaherezo ukagera kuntego yo gushimangira ubutaka.
Ibibazo byuyu mushinga ni:
1. Kubaka mu ruganda bifite uburebure bwa m 12, umwanya wubwubatsi ni muto, gucukura diameter 600mm nuburebure bwa 20 ~ 25m.
2. Geologiya ahanini isubiza inyuma sili, amabuye manini kandi menshi, bityo ibyobo biroroshye gusenyuka.
3. Isima ya sima yatewe mu cyuho no mu cyuho byaviriyemo gukomera kutaringaniye mugihe cyo gucukura, bigatuma ishobora gutandukana.Kugira ngo ibyo bibazo bikemuke, abashakashatsi bo muri Tyhen Foundation bateguye igisubizo cya tekiniki.Bahisemo abakora ubuhanga kandi bakoresheje ibyiza bya KR90A yo kuzenguruka ibyuma, bakoresheje imvange yumucanga wo hasi-kabiri hamwe numutwe wo gucukura.Ubu buryo bwabafashaga kugenzura umuvuduko wikigero no gukoresha inyungu zacyo zo hejuru, bakinjira mubyiciro byuzuye.Kubera iyo mpamvu, ibiciro byubwubatsi byagabanutse kubakiriya, bashimwa bose hamwe nabafatanyabikorwa bambere b'umushinga.
Tysim KR90A izengurutsa imashini iranga moteri ya 86kW, ipima toni 25, kandi irashobora gutobora umwobo ufite diametero kuva kuri 400mm kugeza 1200mm, hamwe nubujyakuzimu bwa metero 28.Igikoresho cyateguwe nubwubatsi bworoshye, bigatuma ingufu zikoreshwa na moteri bitewe nuburemere bwacyo.Mugihe cyubwubatsi bingana, imbaraga nyinshi za moteri zahariwe ibikorwa byo gucukura.Byongeye kandi, inkoni zo gucukura zikoreshwa hamwe nicyuma zoroheje, zituma kuzamura cyane no kugabanya umuvuduko wa 75m / min mugihe kimwe cyumutekano.Umuvuduko wo kuzunguruka urashobora kugera kuri 5r / min, kandi umutwe wimbaraga urashobora kuzunguruka vuba kuri 8-30r / min.Igishushanyo cyerekana ubutaka bwinjira vuba, gukoresha peteroli nkeya, hamwe nubwubatsi bunoze.
