1. Mawu Oyamba
Rotary Drilling Rig ndi makina omangira oyenera kubowola pobowola pakupanga zomangamanga. M'zaka zaposachedwa, yakhala mphamvu yayikulu pakumanga maziko a mulu pomanga mlatho ku China. Ndi zida zosiyanasiyana zobowola, makina obowola ozungulira ndi oyenera kubowola mowuma (ozungulira pang'ono), chonyowa (chidebe chozungulira) ndi zigawo zamiyala (core drill). Ili ndi mawonekedwe amphamvu yoyika kwambiri, torque yayikulu, kuthamanga kwakukulu kwa axial, kusinthasintha kosinthika, magwiridwe antchito apamwamba komanso magwiridwe antchito ambiri. Mphamvu yovotera mozungulira nthawi zambiri imakhala 125-450kW, torque yamagetsi ndi 120-400kN.•m, pazipita dzenje awiri akhoza kufika 1.5-4m, ndi pazipita dzenje kuya ndi 60-90m, amene akhoza kukwaniritsa zofunika zosiyanasiyana yaikulu yomanga maziko.
Pomanga mlatho m'malo ovuta kwambiri, njira zomangira milu zomwe zimagwiritsidwa ntchito nthawi zambiri ndi njira yofukula pamanja ndi njira yobowola. Njira yofukula pamanja ikutha pang'onopang'ono chifukwa cha nthawi yayitali yomanga maziko a milu, teknoloji yakale, ndi kufunikira kwa ntchito zophulika, zomwe zimabweretsa zoopsa ndi zoopsa; Palinso mavuto ena ogwiritsira ntchito zobowola pomanga, zomwe zimawonekera kwambiri pakubowola kwapang'onopang'ono komwe kumayendera mumiyala yolimba, ngakhalenso kusabowola tsiku lonse. Ngati karst ya geological itakula bwino, kubowola kupanikizana kumachitika nthawi zambiri. Kubowola kukachitika, kupanga mulu wobowola nthawi zambiri kumatenga miyezi 1-3, kapena kupitilira apo. Kugwiritsa ntchito makina obowola mozungulira pomanga maziko a milu sikungowonjezera liwiro la zomangamanga ndikuchepetsa ndalama zomanga, komanso kumawonetsa kupambana koonekeratu pakumanga.
2. Makhalidwe a njira zomangira
2.1 Liwiro lopanga pore
Kapangidwe ka dzino ndi kapangidwe ka rock core drill bit of the rotary drilling rig amapangidwa potengera chiphunzitso cha kugawikana kwa miyala. Imatha kubowola mwachindunji pamwala, zomwe zimapangitsa kuti pakhale liwiro lobowola komanso kupititsa patsogolo ntchito yomanga.
2.2 Zabwino kwambiri pakuwongolera khalidwe
Zipangizo zobowola zozungulira nthawi zambiri zimakhala ndi dzenje la pafupifupi 2 metres (lomwe limatha kukulitsidwa ngati dothi lakumbuyo pa dzenjelo ndi lokhuthala), ndipo chotchingiracho chimatha kuphatikizira chotengeracho, chomwe chingachepetse kukhudzika kwa dothi kudzenje. pa mulu wobowoleredwa; Chombo chobowola chozungulira chimakhala ndi ngalande yokhwima pansi pamadzi yothira mulu wa konkriti, womwe ungapewe zotsatira zoyipa za matope omwe amagwa kuchokera ku dzenje ndi dothi lomwe limapangidwa panthawi yothira; Rotary drilling rig ndi makina opangira maziko omwe amaphatikiza sayansi yamakono ndiukadaulo. Panthawi yobowola, imakhala yolondola kwambiri pamayendedwe, kuyang'ana kwa miyala pansi pa dzenje, ndikuwongolera kutalika kwa mulu. Panthawi imodzimodziyo, chifukwa cha kuchepa kwazing'ono pansi pa dzenje, n'zosavuta kuyeretsa dzenje, kotero kuti ubwino wa zomangamanga za mulu umatsimikiziridwa mokwanira.
2.3 Kukhazikika kwamphamvu ku mapangidwe a geological
Chombo chobowola chozungulira chimakhala ndi zobowola zosiyanasiyana, zomwe zitha kugwiritsidwa ntchito pazinthu zosiyanasiyana monga mchenga, zigawo za nthaka, miyala, miyala, ndi zina zambiri, popanda malire.
2.4 Kuyenda kosavuta komanso kuyendetsa mwamphamvu
Chassis ya makina obowola mozungulira amatengera chassis chofufutira, chomwe chimatha kuyenda chokha. Kuphatikiza apo, zida zobowola zozungulira zimatha kugwira ntchito modziyimira pawokha, kukhala ndi kuyenda mwamphamvu, kutengera malo ovuta, ndipo safuna zida zothandizira kukhazikitsa ndi kusokoneza. Amakhala ndi malo ang'onoang'ono ndipo amatha kuyendetsedwa ndi makoma.
2.5 Kuteteza chilengedwe ndi ukhondo wa malo omanga
Makina obowola mozungulira amatha kugwira ntchito m’miyala yopanda matope, zomwe sizimangochepetsa kuwononga madzi komanso zimapeŵa kuipitsidwa kwa malo ozungulira obwera chifukwa cha matope. Chifukwa chake, malo omangira pobowola makina ozungulira amakhala aukhondo ndipo amawononga pang'ono chilengedwe.
3. Kuchuluka kwa ntchito
Njira yomangira imeneyi ndi yoyenera pobowola milu yokhala ndi makina obowola mozungulira m'miyala yolimba komanso yosalimba komanso yolimba kwambiri.
4. Mfundo ya ndondomeko
4.1 Mfundo Zopangira
Potengera mfundo yogwirira ntchito yobowola mozungulira, kuphatikizira ndi momwe miyala imagwirira ntchito komanso chiphunzitso choyambirira cha kugawikana kwa miyala ndi makina obowola mozungulira, milu yoyesera idabowoleredwa m'mipangidwe ya miyala yamwala yolimba yolimba kwambiri. Zofunikira zaukadaulo ndi zizindikiro zachuma za njira zosiyanasiyana zobowola zomwe zimagwiritsidwa ntchito ndi makina obowola mozungulira adawunikidwa mowerengera. Kupyolera mu kuyerekeza ndi kusanthula mwadongosolo mwaukadaulo ndi zachuma, njira yomangira milu yobowola yozungulira m'miyala ya miyala ya miyala yolimba yokhala ndi miyala yolimba idatsimikiziridwa.
4.2 Mfundo yaukadaulo wakubowola pobowola mozungulira pamiyala
Pogwiritsa ntchito makina obowola amitundu yosiyanasiyana kuti awonjezere mabowo pamiyala yolimba, malo aulere pansi pa dzenje amapangidwira pobowola mozungulira, kupititsa patsogolo luso lolowera mwala pobowola mozungulira. rig ndikukwaniritsa malowedwe abwino a miyala ndikusunga ndalama zomanga.
