Qhov kev paub ua tiav tshaj plaws ntawm qhib qhov mines, thov cov miners sau
Ua ntej, qhov muaj pes tsawg leeg ntawm peb lub ntsiab ntawm lub qhov qhib mineSteps: Cov pob zeb ore tau muab faib ua ib qho thickness ntawm kab rov tav txheej, nyob rau hauv cov txheej txheem mining txhua theem ua hauj lwm nyob rau hauv qhov chaw ua ib kauj ruam. Txhua kauj ruam yog hu ua ib kauj ruam, thiab nws qhov siab dhau los ua tus kauj ruam siab.
Kauj ruam nqes: lub inclined nto ntawm kauj ruam mus rau sab ntawm lub mining cheeb tsam. Lub kaum sab xis ntawm qhov chaw inclined thiab lub dav hlau kab rov tav hu ua kauj ruam inclination Platform (flat disk): kab rov tav qhov chaw nruab nrab ntawm kab hauv qab thiab kab saum toj kawg nkaus ntawm txoj kab nqes.
Qhov dav ntawm txoj kab hauv qab ntawm txoj kab nqes thiab kab saum toj kawg nkaus ntawm txoj kab nqes yog hu ua platform dav, thiab lub platform hauv blasting, shoveling thiab tsheb thauj mus los yog hu ua lub platform ua haujlwm; qhov dav ntawm ntug ntawm lub blasting pawg thiab cov kab saum toj kawg nkaus ntawm txoj kab nqes yog hu ua qhov siab ntawm lub platform ua haujlwm; thiab lub platform siv los cuam tshuam cov pob zeb zawv zawg yog hu ua lub platform kev nyab xeeb.
Tom ntej no, peb tshwj xeeb tham txog cov txheej txheem mining ntawm qhib qhov miners.
Thib ob, tho kev ua haujlwm
Perforation ua hauj lwm yog thawj txheej txheem ntawm qhib qhov mining, thiab nyob rau hauv tag nrho cov qhib qhov mining txheej txheem, tus nqi ntawm perforation account rau txog 10% -15% ntawm nws tag nrho cov nqi tsim.
1 、 Hauv qab lub qhov drilling rig
Down qhov drilling rig drilling lub kaum sab xis hloov pauv ntau yam, qib siab ntawm kev siv tshuab, txo lub sijhawm ua haujlwm pabcuam, txhim kho kev khiav haujlwm ntawm lub qhov drilling rig, thiab nqes qhov drilling rig mobile thiab hloov tau, cov khoom hnyav yog lub teeb, tsis tshua muaj nqis peev, tshwj xeeb tshaj yog los ntawm cov drilling ntawm ntau yam slanting qhov los tswj cov qib ore, tuaj yeem tshem tawm cov hauv paus hauv qab, txo cov blocks loj, thiab txhim kho qhov zoo ntawm blasting. Yog li ntawd, down qhov drilling rigs yog dav siv nyob rau hauv me me thiab nruab nrab mines nyob rau hauv tsev thiab txawv teb chaws, thiab yog haum rau perforating nruab nrab thiab nyuaj ore pob zeb.
2, tumbler drilling rig
Toothed Wheel Drilling Rig yog ib hom tshiab tshiab ntawm cov cuab yeej drilling tsim los ntawm kev siv lub tshuab drilling, uas muaj cov yam ntxwv ntawm kev ua haujlwm siab perforating, tsis muaj nqi khiav lag luam, qib siab ntawm kev siv tshuab thiab automation, thiab nws tsim nyog rau perforating ntau yam hardnesses. ore thiab pob zeb, thiab nws tau dhau los ua cov khoom siv perforating feem ntau siv hauv cov mines qhib thoob plaws ntiaj teb.
3 、 Pob zeb drilling dolly
Pob zeb Drill Trolley yog ib hom tshiab ntawm cov khoom siv pob zeb drilling uas tau tshwm sim nrog kev txhim kho kev lag luam mining. Nws yog ib qho los yog ob peb lub pob zeb xyaum ua ke nrog cov tshuab tsis siv neeg ntsia tau rau hauv ib qho tshwj xeeb drilling caj npab los yog lub platform, thiab muaj cov txheej txheem taug kev, kom lub pob zeb xyaum ua haujlwm kom ua tiav cov tshuab.
Kev ua haujlwm tawg
Lub hom phiaj ntawm kev ua haujlwm blasting yog txhawm rau rhuav tshem cov tawv tawv ore pob zeb thiab muab kev khawb ntawm qhov tsim nyog rau kev ua haujlwm mining. Nyob rau hauv tag nrho cov nqi ntawm qhib qhov mining, blasting nqi account rau li 15-20%. Qhov zoo ntawm blasting, tsis tsuas yog cuam tshuam ncaj qha rau cov mining, tsheb thauj mus los, ntxhib crushing thiab lwm yam khoom siv, tab sis kuj cuam tshuam rau tag nrho cov nqi ntawm cov mine.
1, qhov ntiav qhov blasting
Qhov tob blasting siv ib txoj kab me me ntawm lub plhaub qhov, feem ntau yog li 30-75 hli, qhov tob ntawm lub plhaub qhov. Feem ntau tsawg dua 5 meters, qee zaum mus txog 8 meters los yog li ntawd, xws li drilling nrog lub pob zeb laum dolly, qhov tob ntawm lub qhov tuaj yeem nce ntxiv. Qhov tob qhov blasting yog tsuas yog siv rau kev tsim cov me me qhib-qhov mines los yog quarries, pob zeb caving, qhov excavation, qhov tawg thib ob ntawm tawg, tshiab qhib-qhov mine pob ua, tsim ntawm txoj kab nqes ntawm qhib ib leeg- phab ntsa ditch kev thauj mus los thiab qee qhov tshwj xeeb blasting.
2, qhov tob blasting
Sib sib zog nqus hole blasting yog kev siv cov cuab yeej drilling los laum qhov tob, raws li cov mining explosive charge space blasting method. Sib sib zog nqus qhov blasting nyob rau hauv qhib qhov mines yog tsuas yog raws li nyob rau hauv zus tau tej cov kauj ruam blasting. Qhov sib sib zog nqus blasting drilling cov cuab yeej yog tsuas yog siv nyob rau hauv daim ntawv thov ntawm submerged drilling thiab tusk drilling. Nws cov drilling tuaj yeem laum ntsug qhov tob, tab sis kuj tuaj yeem laum inclined qhov. Kev thauj khoom ntawm qhov inclined yog ntau yam sib xws, thiab cov blasting zoo ntawm cov pob zeb ore zoo dua, tsim cov xwm txheej zoo rau kev ua haujlwm mining thiab chaw thau khoom. Yuav kom txo tau cov seismic nyhuv thiab txhim kho qhov zoo ntawm blasting, nyob rau hauv tej yam tej yam kev mob yuav tsum tau coj nyob rau hauv loj qhov chaw ntawm txawv blasting, loading los yog hauv qab ntawm cov huab cua ncua sij hawm loading thiab lwm yam kev ntsuas nyob rau hauv thiaj li yuav txo tus nqi ntawm blasting, kom ua tau zoo dua. nyiaj txiag pab.
3, chamber blasting
Refuge blasting yog ib tug kuj loj los yog ib tug loj tus naj npawb ntawm explosives, ntsia nyob rau hauv lub blasting chamber qhov blasting txoj kev. Qhib-qhov mines tsuas yog siv nyob rau hauv lub peev kev tsim kho lub sij hawm thiab nyob rau hauv tej yam kev mob, quarries nyob rau hauv tej yam kev mob thiab nyob rau hauv qhov kev thov tsuas yog loj heev thaum siv.
4, multi-kab qhov sib txawv blasting txoj kev
Nyob rau hauv xyoo tas los no, nrog lub peev xwm ntawm lub thoob excavator thiab qhov ua kom muaj peev xwm ntau lawm ntawm qhov qhib mines, cov mining ib txwm yuav tsum tau qhib-qhov mines blasting txhua zaus cov nyiaj blasting kuj ntau dua, vim li no, hauv tsev. thiab txawv teb chaws qhib-qhov mining nyob rau hauv dav siv ntawm ntau-kab qhov sib txawv blasting, multi-kab qhov sib txawv blasting extrusion blasting thiab lwm yam loj-scale blasting txoj kev. Qhov zoo ntawm ntau qhov sib txawv ntawm qhov sib txawv blasting: ntau qhov blasting, txo tus naj npawb ntawm cov blasts thiab tsis txhob siv phom sij, txhim kho kev siv cov khoom siv mining Txhim kho cov crushing zoo ntawm cov pob zeb ore, cov nqi ntau yog 40% -50% tsawg dua ib kab qhov blasting Txhim kho qhov ua tau zoo ntawm cov khoom siv perforating txog 10% -15%, uas yog vim qhov nce ntawm kev siv lub sijhawm ua haujlwm thiab cov khoom siv perforating thiab blasting tom qab txo tus naj npawb ntawm kev ua haujlwm hauv cheeb tsam filling. txhawm rau txhim kho kev ua haujlwm ntawm cov khoom siv mining thiab kev thauj mus los txog li 10% -15%.
5, multi-kab qhov sib txawv nyem blasting txoj kev
Hais txog kev ua hauj lwm lub ntsej muag residual explosive pawg nyob rau hauv cov ntaub ntawv ntawm multi-kab qhov sib txawv blasting. Qhov muaj nyob ntawm cov pob ballast, los tsim cov xwm txheej rau extrusion, ntawm ib sab, tuaj yeem txuas ntxiv lub sijhawm zoo ntawm blasting, txhim kho kev siv cov khoom tawg thiab crushing; ntawm qhov tod tes, tuaj yeem tswj qhov dav ntawm pawg tawg, kom tsis txhob tawg ntawm cov pob zeb ore. Multi-kab qhov sib txawv nyem blasting sib txawv lub sijhawm sib txawv tshaj li qhov sib txawv sib txawv 30% -50% tsim nyog, qhib qhov mines feem ntau siv 50-100ms.
