Nkag siab txog daim ntawv thov ntawm handheld laser rangefinder hauv cov chaw mining hauv av
Raws li hom rangefinder, handheld laser rangefinder muaj cov haujlwm tshwj xeeb thiab cov yam ntxwv piv rau cov rangefinders zoo tib yam. Peb txhawb nqa thiab siv nws thiab muag rau qhov chaw uas cov chaw tsim khoom thiab cov chaw lag luam mining tshwj xeeb xav tau.
Daim ntawv thov ntawm handheld laser rangefinders nyob rau hauv mines mas siv ib tug ua ke ntawm handheld laser rangefinders thiab domestic theodolites los tsim ib tug semi chaw nres tsheb yam tsis muaj prism, uas yog siv rau ntsuas taw tes hauj lwm, seem heights, thiab ntim nyob rau hauv underground mining chaw.
Yuav ua li cas yog thawj txoj kev ntsuas hauv av ua ntej ib chav tsev yuav ib lub handheld rangefinder? Cia peb mloog cov lus ntawm tus neeg saib xyuas lub ntsuas ntsuas: lawv tau siv lub theodolite, ib daim tawv ntoo, ib tug pas nuv ntses, thiab lub tshuab pulse range finder los ntsuas qhov chaw hauv av. Lub ntsiab drawbacks ntawm txoj kev no yog:
1. Tsawg ntsuas qhov tseeb. Muaj cov ntaub ntawv pov thawj; Thaum kawg ntawm xyoo 1998, ob pab pawg tshawb fawb geological tau sib koom ua ke ntsuas qhov ntim ntawm thaj chaw mining, ua rau ib pab pawg ntsuas 55000 cubic meters thiab lwm pab pawg ntsuas 68000 cubic meters. Ntsuas ib qho kev ntsuas tus nqi ntawm ib lub sij hawm, tab sis muaj qhov sib txawv tseem ceeb ntawm ntau qhov kev ntsuas, thiab qhov tshwm sim yog tias lawv tsis kam ntsuas txuas ntxiv.
2. Kev nrawm nrawm thiab ua haujlwm qis. Qhov chaw ua haujlwm hauv av tsis tuaj yeem muab piv rau ib puag ncig hauv av txhua. Vim muaj cov kev txwv xws li cov dej hauv av tsis zoo, lub teeb ci tsis pom kev, thiab qhov coefficient ntawm kev ntsuas qis, qhov ntsuas nrawm nrawm thiab qhov ua tau zoo kuj tseem qis. Feem ntau, qhov ntsuas ntsuas yuav siv ntau zaus ntau dua li lub sijhawm ntsuas ib txwm.
3. Txawm hais tias domestic pulse handheld rangefinders kuj tuaj yeem ntsuas qhov deb, vim yog siv ultrasonic rangefinders, tib neeg tsis tuaj yeem pom txoj hauj lwm ntawm lub hom phiaj taw tes, thiab qhov ntsuas qhov ntau yog luv luv thiab qhov tseeb yog tsawg, zoo heev limiting nws ntau yam kev siv.
Yog li dab tsi txog cov kev hloov pauv tom qab siv lub handheld laser rangefinder? Cia peb saib:
Hauv kev ntsuas hauv av, nws tsuas yog tsim nyog rau kev ntsuas cov neeg ua haujlwm txhawm rau txhim kho theodolite thiab ntsuas qhov deb, thiab lub hom phiaj tsis tas yuav tsum muaj tus neeg sawv cev. Kev ntsuas kev ua haujlwm tuaj yeem ua tiav zoo, muaj kev nyab xeeb, thiab raug rau lub sijhawm luv luv, kov yeej qhov tsis zoo ntawm kev qeeb qeeb, kev ua haujlwm tsis zoo, thiab qhov tsis zoo yav dhau los. Tshwj xeeb tshaj yog nyob rau hauv kev ntsuas hauv av, qhov kom zoo dua ntawm cov khoom siv ntawm tes laser nrug ntsuas uas tuaj yeem pom cov ntsiab lus liab laser tshwj xeeb yog qhuas los ntawm cov neeg ua haujlwm ntsuas. Hauv kev ntsuas hauv av, lub handheld laser rangefinder kuj tseem siv tau nyias, uas yooj yim heev thiab tuaj yeem khaws cov ntaub ntawv ntsuas ntau yam tsis tas yuav tsum muaj cov ntaub ntawv ntsuas hauv av.
Ntxiv nrog rau qhov yooj yim rau kev siv hauv av, handheld laser rangefinders kuj siv tau rau kev ntsuas sab nraum zoov thiab lofting.
