Hunhu hwematombo akaomarara akadai segranite uye njodzi yekuumbwa kwemakomba. Pakugadzira nheyo dzemakomba emabhiriji makuru akawanda, makomba anofanirwa kupinda mudombo rakaomarara rakapwanyika kusvika pakadzika, uye dhayamita yemakomba akagadzirirwa nheyo idzi dzemakomba inonyanya kupfuura 1.5mm. Kunyangwe kusvika 2m. Kuboora mumatombo akaomarara akadaro ane dhayamita yakakura kunoisa zvinodiwa zvakanyanya pasimba remuchina nekumanikidzwa, zvinowanzoda torque inopfuura 280kN.m michina. Pakuboora mumhando iyi yekuumbwa, kurasikirwa kwemazino ekuboora kwakakura kwazvo, uye zvinodiwa zvepamusoro zvinoiswa pakudzivirira kudedera kwemuchina.
Nzira yekuvaka yekuboora inotenderera inoshandiswa mumatombo akaomarara akadai segranite nejecha. Matanho anofanirwa kutorwa kubva pane zvinotevera kuti kuvandudza mashandiro ekugadzira maburi uye kuderedza njodzi.
(1) Midziyo ine simba re280kN.m zvichikwira inofanira kusarudzwa kuti ishandiswe pakuvaka kuchera. Gadzirira mazino ekuboorera ane kuoma kwakanyanya uye mashandiro ari nani ekukuya pachine nguva. Mvura inofanira kuwedzerwa kune anhydrous formations kuderedza kupera kwemazino ekuboorera.
(2) Gadzirisa maturusi ekuboorera nemazvo. Pakuboorera makomba emapango makuru mumhando iyi yekugadzirwa, nzira yekuboorera yakarongwa inofanira kusarudzwa. Padanho rekutanga, chibooreso chebharero chakareba chine dhayamita ye600mm ~ 800mm chinofanira kusarudzwa kuti chibudise zvakananga pakati pechinhu uye chigadzire chiso chakasununguka; kana kuti chibooreso chidiki chedhayamita chinotenderera chinofanira kusarudzwa kuti chiboore kuti chigadzire chiso chakasununguka.
(3) Kana makomba akakombama akaitika munzvimbo dzakaoma dzematombo, zvinonetsa zvikuru kutsvaira makomba. Saka, kana ukasangana nedombo rakakombama, rinofanira kugadziriswa usati watanga kuchera zvakanaka.
