SWMC, lub chaw tsim khoom ntawm lub tshuab drilling, tib txoj hauv kev muab cov khoom tiav tshuab rau cov neeg siv khoom, siv ntau tshaj 20 xyoo ntawm kev lag luam kev lag luam los muab cov kev daws teeb meem txhim khu kev qha rau cov neeg siv cov tshuab drilling subsurface thiab pab cov neeg siv khoom kom ua tiav cov hom phiaj engineering nrog Tus nqi qis thiab kev ua haujlwm siab.Nws tau tshaj tawm tias kev koom tes ntawm Xuanhua drilling rig chaw tsim tshuaj paus SWMC thiab BEIFANG chaw txua txiag zeb tsis txwv rau kev muab cov cuab yeej siv.Thaum BEIFANG chaw txua txiag zeb yog qhov xav tau ceev ntawm cov ntaub ntawv, SWMC kuj muab kev pabcuam leasing ntawm X5A-DTH.BEIFANG chaw txua txiag zeb tsis tas yuav nqis peev nyiaj ntau, uas txuag cov nqi tsim khoom thiab txo cov kev pheej hmoo ntawm cov khoom siv.The SWMC drilling rig tuaj yeem nkag siab zoo txog cov kev xav tau ntawm BEIFANG chaw txua txiag zeb thiab muab cov kev daws teeb meem zoo rau nws txoj kev loj hlob yav tom ntej.

SWMC tab tom muab cov cuab yeej drilling rau BEIFANG Quarry, nyob hauv Chaoyang nroog, Liaoning xeev, los pab nws txhim kho kev ua haujlwm blasting.

Lub tuff pom nyob rau hauv BEIFANG chaw txua txiag zeb yog cov zoo tshaj plaws sandstone.Lub chaw txua txiag zeb npaj mine txog 3 lab cubic meters ntawm pob zeb no txhua xyoo.

Peb tuaj yeem xav txog tias yog tias peb laum lub qhov nrog qhov tob ntawm 22m thiab txoj kab uas hla ntawm 115mm nrog rauj, yuav muaj qhov pom tseeb inclination thiab qhov drilling efficiency yuav txo qis. Yog li ntawd, BEIFANG quarry yuav 2 teeb ntawm SWMC X5A-DTH tag nrho hydraulic submersible tshuab tsim los ntawm SWMC.Nws tuaj yeem ua haujlwm nrog kev kub siab submersible impellers, thiab kev ua haujlwm siab txog li 21bar.

Lub pob zeb hardness yog nruab nrab hardness F = 8-10.Tom qab rov sim dua hauv cov chaw txua txiag zeb, nws tau txiav txim siab los txais yuav cov txheej txheem inclined qhov nrog aperture ntawm 140mm thiab lub kaum sab xis ntawm 30 degrees los ntawm txoj kab ntsug.Nyob rau hauv txoj kev no, cov kauj ruam ruaj ntseg tuaj yeem ua tau zoo dua, cov kab tsis sib haum tuaj yeem sib xws, thiab feem pua ​​​​ntawm cov khoom seem thiab cov seem yuav raug txo.

X5A-DTH tsim los ntawm Taiye, lub chaw tsim khoom drilling rig hauv Xuanhua, yog siv los txhim kho kev ua haujlwm zoo.BEIFANG tau xaiv qhov kev xyaum no vim tias nws tuaj yeem tswj tau lub kaum sab xis drilling, ntxuav lub qhov thiab du lub qhov phab ntsa, laum qhov tob thiab laum sai dua.

BEIFANG chaw txua txiag zeb tso rau pem hauv ntej tshwj xeeb cov cai rau kev tsim khoom.Peb feem ntau hais tias, "qhov zoo dua qhov zoo ntawm qhov tsim, qhov zoo dua qhov blasting, thiab ntawm chav kawm, qhov zoo dua qhov tshwm sim. Hauv lwm lo lus, txo cov nqi ntawm cov blasting thib ob tuaj yeem ua kom cov khoom tsim tau ntxiv.

X5A-DTH laum rig yog kev ua haujlwm ywj pheej ntawm lub rig, nruab nrog kev siv cua siab DTH impacter drilling tsheb cua compressor, muab BEIFANG quarry yog 2 lub tshuab ua tiav, vim tias yuav tsum tau inclined qhov, yog li xav tau kev tsim tshwj xeeb ntawm cov roj hmab plua plav npog, kuj vim yog lub pob zeb nyuaj, xyaum xav tau tshwj xeeb parameter Chaw.

Piv txwv li, cov qauv geological ntawm cov chaw txua txiag zeb yuav tsum xaiv qhov ceev me ntsis nrog cov kab hniav los yog sib xyaw ntawm cov hniav ntawm cov hniav thiab cov hniav caij nplooj ntoos hlav.Lub laum me ntsis yog tig ntawm 70 thiab 80 revolutions ib feeb, thiab pob zeb fissures uas tsis pom. Hauv qab ntawm qhov chaw tuaj yeem ua rau lub qhov tsis tuaj yeem tsim, lossis cov hlua tho tau daig hauv lub qhov, lossis lub siab poob.

Nyob rau hauv cov nqe lus ntawm ntau lawm efficiency, rau qhov 22 meters sib sib zog nqus, lub sij hawm drilling tau raug txo los ntawm 1 lub qhov rau 45min mus rau qhov nruab nrab ntawm 1 qhov ntawm 30min.
