Uyu munsi, reka tuvuge kubyerekeye amatafari atukura yigihugu

### ** 1. Uburemere bwihariye (ubucucike) bwamatafari atukura **
Ubucucike (uburemere bwihariye) bwamatafari atukura mubusanzwe buri hagati ya garama 1,6-1.8 kuri santimetero kibe (kilo 1600-1800 kuri metero kibe), bitewe nubushobozi bwibikoresho fatizo (ibumba, shale, cyangwa amakara yamakara) hamwe nuburyo bwo gucumura.

### ** 2. Uburemere bwamatafari asanzwe atukura **
- * * Ingano isanzwe * *: Ubushinwa busanzwe bwubakishijwe amatafari ni * * 240mm × 115mm × 53mm * * (ubunini bugera kuri * * 0.00146 metero kibe * *). Metero kibe imwe yamatafari yumutuku asanzwe yigihugu ni ibice 684.
- *. Ibice bigera kuri 402 byamatafari yumutuku asanzwe yigihugu kuri toni
(Icyitonderwa: Amatafari yubusa cyangwa amatafari yoroheje arashobora kuba yoroshye kandi akeneye guhinduka ukurikije ubwoko bwihariye.)

### ** 3. Igiciro cyamatafari atukura **
- * * Igiciro cyibiciro * *: Igiciro cya buri matafari atukura ni hafi * * 0.3 ~ 0.8 Amafaranga * *, byatewe nimpamvu zikurikira:
-Itandukaniro ry’akarere: Uturere dufite politiki ihamye y’ibidukikije (nkimijyi minini) ifite ibiciro byinshi.
- * * Ubwoko bubi * *: Amatafari y'ibumba agenda aragenda buhoro buhoro kubera kubuza ibidukikije, mugihe amatafari ya shale cyangwa amakara ari menshi.
-Ibipimo by'umusaruro: Umusaruro munini urashobora kugabanya ibiciro.
-Icyifuzo: Baza mu buryo butaziguye uruganda rwa tile rwaho cyangwa ibikoresho byo kubaka isoko ryigihe-nyacyo.

### ** 4. Igipimo cyigihugu cyamatafari acumuye (GB / T 5101-2017) **
Ibipimo biriho mubushinwa ni * * “GB / T 5101-2017 Amatafari asanzwe yacumuye” * *, kandi ibyangombwa bya tekiniki byingenzi birimo:
-Ubunini no kugaragara: ubunini bwemewe gutandukana ± 2mm, nta nenge zikomeye nko kubura impande, inguni, ibice, nibindi.
-Icyiciro cy'imbaraga: kigabanijwe mu nzego eshanu: MU30, MU25, MU20, MU15, na MU10 (urugero, MU15 byerekana imbaraga zo kwikuramo impuzandengo ya ≥ 15MPa).
-Kuramba: Igomba kuba yujuje ibisabwa kugirango irwanye ubukonje (nta byangiritse nyuma yizuba ryikonje), igipimo cyo kwinjiza amazi (muri rusange ≤ 20%), no gutobora lime (nta guturika kwangiza).
-Ibisabwa ku bidukikije: Ugomba kubahiriza imipaka y’ibyuma biremereye hamwe n’imyanda ihumanya radio muri GB 29620-2013.

### * * Kwirinda **
-Ubundi buryo bwangiza ibidukikije: Amatafari yumutuku wibumba arabujijwe gukoreshwa kubera kwangirika kwubutaka, kandi birasabwa guhitamo amatafari yamatafari. Amatafari acumuye akozwe mumyanda ikomeye nk'amatafari ya slag amatafari, amatafari ya shale, n'amatafari ya gangue.
- * * Kwakira ubwubatsi * *: Mugihe cyo gutanga amasoko, birakenewe kugenzura icyemezo cyuruganda na raporo yubugenzuzi bwamatafari kugirango hubahirizwe ibipimo byigihugu.
