Daim ntawv thov ntawm handheld laser range finder hauv mines
Raws li hom rangefinder, lub handheld laser rangefinder muaj cov haujlwm tshwj xeeb thiab cov yam ntxwv piv nrog cov rangefinders zoo tib yam. Hauv kev siv mining, nws tsuas yog siv cov theodolite hauv tsev los ua ke rau hauv ib nrab ntawm qhov chaw nres tsheb. Nws yog siv los ntsuas qhov chaw nyob, ntu qhov siab, chaw nres tsheb, thiab lwm yam hauv cov chaw nres tsheb hauv av. Ua ntej ib chav tsev yuav ib lub handheld rangefinder, dab tsi yog thawj qhov kev ntsuas hauv av? Thaum kawg ntawm xyoo 1998, ob pawg tshawb fawb geological tau sib koom ua ke ntsuas qhov ntim ntawm qhov nres. Qhov tshwm sim yog tias ib pawg yog 55,000 cubic meters thiab lwm pab pawg yog 68,{5}} cubic meters. square. Ntsuas tus nqi ntsuas ib zaug. Qhov ntsuas qhov ntsuas yog qhov sib txawv ntawm ib leeg. Qhov tshwm sim yog tias kuv twv tsis txuas ntxiv ntsuas dua. 2. Ua haujlwm qeeb thiab qis. Qhov chaw ua haujlwm hauv av tsis tuaj yeem muab piv nrog rau qhov chaw ib puag ncig. Vim muaj kev txwv tsis zoo hauv av, lub teeb tsaus, thiab qis coefficients, kev ntsuas kev ua haujlwm qeeb qeeb thiab qhov ua tau zoo kuj tseem qis heev. Ib qho ntsuas ntsuas feem ntau siv ob peb zaug ntau dua li lub sijhawm ntsuas ib txwm. 3. Txawm hais tias lub hauv paus mem tes-hom handheld rangefinder kuj tuaj yeem ntsuas qhov deb, vim nws siv ultrasonic ntau, cov neeg tsis tuaj yeem pom txoj hauj lwm ntawm lub hom phiaj. Tsis tas li ntawd, qhov ntsuas qhov ntau yog luv luv thiab qhov tseeb yog qhov tsawg, uas txwv nws txoj kev siv ntau heev. Hauv kev ntsuas hauv av, tus neeg soj ntsuam tsuas yog yuav tsum teeb tsa lub theodolite thiab ntsuas qhov deb, thiab tsis muaj leej twg yuav tsum tau sawv ntawm lub hom phiaj. Kev ntsuas kev ua haujlwm tuaj yeem ua tiav zoo, nyab xeeb thiab raug rau lub sijhawm luv luv, kov yeej cov kev cov nyom dhau los. Nws muaj shortcomings xws li qeeb ceev, tsis tshua muaj efficiency, thiab tsis raug. Hauv particular, qhov zoo ntawm handheld laser rangefinder nyob rau hauv underground ntsuas uas lub liab laser point yuav pom tau tshwj xeeb qhuas los ntawm cov neeg soj ntsuam. Lub handheld laser rangefinder kuj tseem siv tau ib leeg hauv kev ntsuas hauv av, 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, lub handheld laser rangefinder kuj tseem siv tau rau kev ntsuas qhov qhib-cua qhov nqes hav thiab stakeout.
