Kumanga ngalande nthawi zonse kwakhala pachimake pa ntchito yomanga, ndipo n'kovuta kumanga. Zaka za m'ma 1960 zisanafike, kuphatikiza kuboola ndi kuphulitsa kunagwiritsidwa ntchito pomanga ngalande. Zoyipa za njirayi ndizodziwikiratu, chitetezo chophulika sichidziwika, kuipitsidwa kwakukulu kumapangidwa, ndipo mawonekedwe ophulika a ngalandeyo ndi osakhazikika ndipo sangathe kuwongolera molondola. Pambuyo pa zaka za m'ma 1960, mulingo wamakina wamakinawa wasinthidwa kwambiri. Kugwiritsa ntchito mutu wamsewu kwasintha kotheratu njira yobowola ndi kuphulika ya makumbidwe a ngalandeyo. Masiku ano, zida zabwino kwambiri zimakhudzidwa ndi uinjiniya wa ngalande, ndipo odula ng'oma ndi zinthu za rock saw za chilengedwe cha Yichen zimagwira bwino ntchito pomanga ngalandeyo.

Kupanga kwa chodulira ng'oma ndikolondola komanso kuyendetsedwa ndi ukadaulo wa hydraulic. Mano ocheka pa ng'oma yodula amawombana ndi malo omangapo ndikudula midadada ndi miyala ngati zikhadabo, zomwe zimapereka njira yatsopano yopangira chuma pofukula ngalandeyo. Kumayambiriro kwa Okutobala 2010, makina a Yichen mphero ndi kukumba akhala aluso muukadaulo wamakina.

Ku Hutubi, Shaanxi, Bambo Li ndi mwana wawo wamwamuna anagwira ntchito yofukula ngalande yotalika mamita 6 * 5 m’lifupi mwake. Bambo Li adasintha chofufumitsa cha Hitachi 200 kukhala mkono wowongoka ndikuyika chodulira ng'oma cha YF-20RW m'malo a Yichen pofukula ngalande. Pankhani ya sandstone, sedimentary rock ndi silty rock mkati mwa ngalandeyo, kuthamanga kwa wodula ng'oma kumakhala pafupifupi 10m tsiku lililonse, ndipo mphamvu ya mphero ndiyokwera kwambiri.

Panthawiyi, macheka a miyala adzasankhidwa kuti adulidwe. Macheka a thanthwe amapangidwa ndi zinthu zopangidwa ndi diamondi, zomwe zimakwanira kuthana ndi miyala yolimba. Njira ndi kuya kwa macheka zidzafufuzidwa molingana ndi mikhalidwe yeniyeni ya thanthwe ndipo ndondomeko yomanga idzatsimikiziridwa.

Kutengera chitsanzo cha Xiamen tunnel m'chigawo cha Fujian, China Railway idakumana ndi ngalande ya granite pakufukula, kotero omangamanga adayika Yichen YS-20SS pa chofukula cha matani 20 kuti adulidwe, ndikuchigogoda ndi nyundo yophwanyidwa pambuyo podula. kuti azindikire kufukulidwa kwa nkhope yolimba ya rock.
