Exploitation Method of Granite Mines - Blast Hole Blasting

Geological tej yam kev mob thiab mineral yam ntxwv ntawm txhua granite mine yog txawv. Vim tias lub hom phiaj tseem ceeb ntawm granite ornamental pob zeb mining yog kom tshem tawm cov khoom pov tseg loj (qhov loj ntawm cov pov tseg, qhov zoo dua hauv kev txiav txim siab), tsuas yog los ntawm kev txiav txim siab tag nrho cov strata, pob qij txha thiab fissures ntawm lub cev ore thiab xaiv txoj kev mining uas tsim nyog tshaj plaws. thiab cov phiaj xwm tuaj yeem ua kom cov khoom pov tseg loj tuaj yeem ua tiav thiab tshem tawm cov pov tseg ntawm pob zeb.

 

 

Blast qhov blasting
Blast-qhov blasting tseem hu ua ntiav-qhov blasting, uas feem ntau ua tiav lub hom phiaj ntawm kev sib cais ntawm pob zeb los ntawm lub roob los ntawm kev khawb ib tug xov tooj ntawm blasting qhov (tsawg dua 50 hli inch thiab 4-5 m nyob rau hauv ntev) rau hauv pob zeb, loading tus nqi yuav tsum tau them, thaiv thiab pib lub blasting.

Obviously, ntau lawm efficiency ntawm mining granite los ntawm txoj kev no yog tsawg heev. Tsis tas li ntawd, vim muaj kev cuam tshuam ntawm kev tawg ntawm lub roob qauv, tsis yog tsuas yog cov khoom siv pob zeb hauv lub roob yuav raug rhuav tshem, cov kab nrib pleb yuav raug tsim, nws nyuaj rau tsim cov khoom siv pov tseg, qhov tshwm sim ntawm cov khoom seem yuav raug nce ntxiv, tab sis kuj tseem yuav tsim cov khoom pov tseg. nce qhov tshwm sim ntawm kev sib tsoo thiab kev sib tsoo hauv lub mine, uas yuav muaj kev cuam tshuam loj heev rau lub mine tag nrho thiab pov tseg cov pob zeb loj heev. Yog li ntawd, txoj kev no tsis yog ua tau.

Ntawm qhov tod tes, txawm hais tias lub tshuab drilling tau hloov phau ntawv drilling hauv feem ntau cov pob zeb mines tam sim no, nws tseem yog ib qho nyuaj rau kev tho qhov ntsug thiab cov khoom tawg yog qhov tsis paub tseeb.

Nyob rau hauv lub xyoo pua 20th lig, ntau lub teb chaws tau tso tseg txoj kev rov qab mining no txhawm rau tiv thaiv ib puag ncig ntuj thiab ua kom siv tau zoo ntawm cov pob zeb ntxhia.

Hauv Suav teb, feem ntau pob zeb mines tau tso tseg txoj kev no, tab sis ob peb lub mines tsis xwm yeem lossis me me tseem siv txoj kev no stealthily.
