Ruzivo rwakakwana rwemigodhi yegomba rakavhurika, ndapota muunganidzwa wevaridzi
Chekutanga, kuumbwa kwezvinhu zvitatu zvegomba rakavhurika mugodhiMatanho: Dombo resimbi rakakamurwa kuita humwe ukobvu hweakachinjika akaturikidzana,mukuita kwemigodhi nhanho imwe neimwe yekushanda munzvimbo inoumba nhanho. Nhanho imwe neimwe inonzi nhanho, uye urefu hwayo hunova hurefu hwenhanho.
Nhanho yakatsetseka: nzvimbo yakarerekera yenhanho kudivi renzvimbo yemugodhi. Kona pakati penzvimbo yakarerekera uye ndege yakachinjika inodaidzwa kuti nhanho inclination Platform (flat disk): nzvimbo yakachinjika yepasi pakati pemutsetse wepasi uye wepamusoro wenhanho nhanho.
Hupamhi pakati pemutsetse wepasi pemateru uye mutsara wepamusoro wemateru unonzi hupamhi hwepuratifomu, uye chikuva mukuputika, kufoshoro nemabasa ekufambisa chinonzi chikuva chekushanda; hupamhi pakati pemucheto wekuputika kwekuputika uye mutsara wepamusoro wemateru inonzi kukwirira kwepuratifomu yekushanda; uye chikuva chinoshandiswa kubata dombo rinotsvedza chinonzi chikuva chekuchengetedza.
Tevere, isu tinonyatso kutaura nezve nzira yekuchera migodhi yakavhurika migodhi.
Chechipiri, basa rokuboora
Perforation basa ndiyo yekutanga nzira yekuvhurika gomba migodhi, uye mune yakavhurika gomba yekuchera migodhi, mutengo we perforation account inosvika 10% -15% yemari yayo yese yekugadzira.
1, Pasi pegomba rekuchera
Kudzika gomba kuchera rig kudhirowa kona shanduko, yakakwira dhigirii yemakanika, kuderedza yekubatsira nguva yekushanda, kunatsiridza mwero wekushandisa wekuchera rig, uye pasi gomba rekuchera rig nhare uye inochinjika, uremu hwemidziyo yakareruka, mutengo wakaderera wekudyara, kunyanya kuburikidza ne kuchera makomba akasiyana-siyana ekudzora giredhi reore, kunogona kubvisa mudzi wepasi, kuderedza zvidhinha zvakakura, nekuvandudza kunaka kwekuputika. Naizvozvo, madhiri ekuchera pasi anoshandiswa zvakanyanya mumigodhi midiki uye yepakati nepakati kumba nekune dzimwe nyika, uye akakodzera perforating yepakati uye yakaoma ore matombo.
2, tumbler drilling rig
Toothed Wheel Drilling Rig imhando nyowani yemazuva ano yemidziyo yekuchera yakagadziridzwa pahwaro hweinotenderera yekuchera rig, ine maficha epamusoro perforating kunyatsoita, mutengo wakaderera wekushandisa, wakakwira dhigirii rekugadzira uye otomatiki, uye inokodzera kuputira kwakasiyana kuomarara kwe. ore nedombo, uye yave midziyo yekuputira inowanzoshandiswa mumigodhi yakavhurika pasi rose.
3、Rock drilling dolly
Rock Drill Trolley imhando nyowani yemidziyo yekuchera dombo iyo yakaonekwa nekuvandudzwa kweindasitiri yemigodhi. Iro rimwe chete kana akati wandei madhiraini pamwe chete neatomatiki propeller akaiswa mune yakakosha yekuchera ruoko kana chikuva, uye ane mafambiro ekufamba, kuitira kuti kudhirowa kwedombo kuwana mechanization.
Kuputika basa
Chinangwa chekuputika kwebasa ndechekuputsa dombo rakaoma rakaoma uye kupa kuchera kwehukuru hwakakodzera hwekushanda kwemigodhi. Mumutengo wakazara wekucherwa kwegomba rakavhurika, mitengo yekuputika inokwana 15-20%. Hunhu hwekuputika, kwete chete hunokanganisa zvakananga kumigodhi, kutakura, kuputika kwakashata uye mamwe mashandisirwo emagetsi, asiwo kunokanganisa mutengo wose wemugodhi.
1, kudzika kwegomba kuputika
Kuputika kwegomba risina kudzika uchishandisa dhayamita diki regomba regoko, kazhinji rinenge 30-75 mm, kudzika kwegomba regoko. Kazhinji isingasviki 5 metres, dzimwe nguva inosvika 8 metres kana zvakadaro, sekuchera nedombo rekudhirowa dolly, kudzika kwegomba kunogona kuwedzerwa. Kuputika kwegomba kusina kudzika kunonyanya kushandiswa kugadzira migodhi midiki-yakavhurika-gomba kana makwari, matombo ematombo, kuchera mugero, kechipiri kuputika kwekuputsika, nyowani yakavhurika-gomba pasuru yekugadzirisa, kuumbwa kwemateru eiyo yakavhurika imwe- madziro ditch yekufambisa yekupinda uye kumwe kumwe kuputika kwakakosha.
2, kuputika kwegomba rakadzika
Pakadzika hole blasting iko kushandiswa kwemichina yekuchera kuchera makomba akadzika, semugodhi unoputika uchaja nzvimbo yekuputika nzira. Kuputika kwegomba rakadzika mumigodhi yegomba rakashama kunonyanya kuenderana nekugadzirwa kwekuputika kwenhanho. Midziyo yekuchera yakadzika gomba inonyanya kushandiswa mukushandiswa kwekuchera pasi pemvura uye kuchera tusk. Kuchera kwayo kunogona kuchera makomba akadzika, asiwo kunogona kuchera makomba akarerekera. Kutakurwa kwemakomba akarerekera kunowedzera yunifomu, uye kuputika kwemhando yedombo re ore kuri nani, kugadzira mamiriro akanaka ekuchera uye kurodha basa. Kuti uderedze seismic athari uye uvandudze kunaka kwekuputika, pasi pemamwe mamiriro anogona kutorwa munzvimbo dzakakura dzekusiyanisa kuputika, kurodha kana kuzasi kwemhepo kupindirana kwemhepo kurodha uye mamwe matanho kuitira kuderedza mutengo wekuputika, kuwana zvirinani. upfumi hunobatsira.
3, kuputika kwekamuri
Refuge blasting inhamba yakati wandei kana nhamba huru yezvinoputika, zvakaiswa mu blasting chamber tunnel blasting method. Migodhi yakavhurika-gomba inoshandiswa chete munguva yekuvaka kukuru uye pasi pemamwe mamiriro ezvinhu, zvikwari mumamiriro ezvinhu uye mukudiwa kwemigodhi yakakura kwazvo kana ichishandiswa.
4, Multi-row gole differential blasting method
Mumakore achangopfuura, nehuwandu hwemabhakiti ekuchera uye nekuwedzera kunoshamisa kwekugadzirwa kwemigodhi yakavhurika-gomba, zvakajairwa zvicherwa zvemigodhi yakavhurika kuputika nguva imwe neimwe apo huwandu hwekuputika huri kuwedzera, nechikonzero ichi, mudzimba. uye kunze kwenyika yakazaruka-gomba migodhi mukushandiswa kwakawanda kwemakomba akawanda-mutsara differential blasting, multi-row makomba differential blasting extrusion blasting uye dzimwe nzira huru dzekuputika. Zvakanakira zveakawanda-mutsara gomba kusiyanisa kuputika: kuwanda kwekuputika, kuderedza kuwanda kwekuputika uye kudzivirira nguva yepfuti, kuvandudza mwero wekushandiswa kwemidziyo yemugodhi Kuvandudza kunaka kwekupwanya kwedombo re ore, huwandu hwakawanda i40% -50% kuputika kwegomba risingasviki mutsara mumwechete Kuvandudza kushanda kwemidziyo yeperforating inenge 10% -15%, imhaka yekuwedzera kwechinhu chekushandiswa kwenguva yekushanda uye midziyo yeperforating uye kuputika mushure mekuderedzwa kwehuwandu hwekushanda munzvimbo yekuzadza. kuvandudza kushanda kwemigodhi nemidziyo yekufambisa inenge 10% -15%.
5, akawanda-mutsara gomba musiyano kusvina kuputika nzira
Zvinoreva basa rakasara rinoputika murwi munyaya ye-multi-row hole differential blasting. Kuvepo kwemurwi weballast, kugadzira mamiriro ekunze, kune rumwe rutivi, kunogona kuwedzera nguva inoshanda yekuputika, kunatsiridza kushandiswa kwezvinoputika nekupwanya mhedzisiro; kune rumwe rutivi, inogona kudzora hupamhi hwemurwi wekuputika, kudzivirira kupararira kwedombo re ore. Multi-row gole differential kusvina kuputika kuputika kusiyanisa nguva pane zvakajairwa kuputika kuputika 30% -50% kwakakodzera, migodhi yegomba yakazaruka inowanzoshandisa 50-100ms.
