Kufambira mberi muHydraulic uye Mvura-Ine Simba DTH Drilling Technology.

1. Zvakanakira Hydraulic Rock Drills

① High Hydraulic Pressure: Kazhinji kubva pagumi kusvika pamakumi maviri neshanu MPa, ine maitiro ekuenda kumiganhu yepamusoro. Izvi zvakati wandei kusvika kumakumi enguva dzakakwirira pane pneumatic pressure.

② High Output Power: Kazhinji pakati pe5 kusvika 20 kW. Mamwe mamodheru, akadai seCOP4050 neATLAS uye HL2000 neTAMROCK, anosvika makumi mana kW, nepo HL4000 ichiwana kusvika 70 kW.

③ Fast Drilling Speed: Kazhinji inowana chiyero chekuchera che 1-3 m / min.

④ Kushanda Kwepamusoro: Kushanda kwe hydraulic rock drills ivo pachavo vanogona kusvika 50%, uye hydraulic pombi inoshanda zvakanyanya kupfuura air compressors. Nekuda kweizvozvo, iyo yakazara simba kushandiswa kwakakwira zvakanyanya kupfuura iyo yepneumatic rock drill system.

2. Kuipa kweHydraulic Rock Drills

① Kurasika Kwemagetsi: Sezvo chibooreso chedombo chiri pamusoro pechibooreso, kurasikirwa kwesimba rekutapurirana kunowedzera nekudzika kwegomba, zvichikonzera kuderera kwekumhanya kwekuchera.

② Yakakwira Drill Rod Wear: Sezvo simba re hydraulic rock drills richiwedzera, kushushikana kuri padanda rekuchera kunowedzerawo, zvichitungamira kumazinga ekukuvara kwakanyanya. Kunyangwe matekinoroji akaita seAtlas Copco's casing drilling inobatsira kuderedza kushushikana, ivo vanowedzera mitengo uye vanotadza kugadzirisa zvachose dambudziko, nekudaro vachidzikamisa simba rekudhirowa. Semuenzaniso, nepo simba reCOP4050 rakaiswa pa40 kW, 30 kW chete ndiyo inoshandiswa kuchera gomba rakadzika kuderedza kushushikana pamidziyo.

③Kutsauswa kweBorehole: Tsvimbo dzeDrill dzinotsungirira zvese zvinokanganisa masimba uye torque, zvichitungamira mukukotama uye deformation, izvo zvinoderedza kurongeka kwechibhorani.

3. ZvakanakiraPasi-paburi (DTH)Drills

① Hapana Kurasikirwa Kwemagetsi Kurasikirwa: Iyo sando inobata zvakananga iyodrill bit, kubvisa kudiwa kwesimba rekufambiswa kwesimba kuburikidza netsvimbo yekuchera, kuve nechokwadi chekumhanyisa kudhirowa kwakafanana zvisinei nekudzika.

② Straight Boreholes: Chibooreso chine kuomarara kwepamusoro, hachiisi pasi pesimba rekukanganisa, uye chinoendesa chete torque ine shoma axial pressure. Izvi zvinodzivirira kukotama uye deformation, kuve nechokwadi kuti yakatwasuka uye yakatsetseka zvibhorani. DTH drills inoita zvirinani mumaumbirwo akatsemuka, akarerekera strata, kana kuomarara kwedombo.

③ Kubvisa Marara Kunoshanda: Iyo yepakati yemagetsi inopeta senge yekugezesa, kunyatsochenesa chibhorani uye kudzivirira zvakanyanya-kuchera.

④ Ruzha Rwakaderera: Sezvo kukanganisa kunoitika pazasi pechibhorani, ruzha rwakadzika zvakanyanya kupfuurapamusoro-sando drills.

⑤ Broad Applicability: Kunze kwezvimiro zvakapfava kwazvo, DTH drills inoshanda zvakakwana mumhando dzese dzematombo, ichipfuura madhiri ematombo epamusoro-sando mukusvikika kwechibhorani dhayamita nekudzika.

Tichifunga mabhenefiti aya, kuchera kweDTH kunoonekwa zvakanyanya seyakanakisa sarudzo, ne90% yemakori ekuBritain anotora nzira iyi.

4. Kuipa kwePneumatic DTH Drills

① Yakaderera Kudzvanya uye Simba: Iyo yekutanga dhiraivha yepneumatic DTH drills ndiyo yakaderera mhepo kudzvanywa uye simba rekubuda, zvichitungamira kunonoke kuchera kumhanya. Kunyange kufambira mberi kwakasimudza mhepo kusvika ku2.5 MPa, iyi ichiri pasi pe hydraulic pressure ye rock drills. Uyezve, high-pressure air compressors inodhura, inoda madhiraivha epamusoro-soro, inoburitsa ruzha, uye inorasikirwa nehunyanzvi munzvimbo dzakakwirira-dzakakwirira.

② Low Energy Utilization Efficiency: Pneumatic DTH drills inoshandisa katatu simba rakawanda pamamita akadhirowa kupfuura hydraulic rock drills.

5. Zvishandiso zveHydraulicDTH Sando

Kuti ubatanidze zvakanakira hydraulic rock drill (high pressure uye kunyatsoshanda) uye DTH drills (straight boreholes), Hausherr wekuGermany akagadzira “Rapid Hydraulic DTH Drill” mukutanga kwema1990. Zvese zviri zviviri kutenderera kwayo uye maitiro ekukanganisa anofambiswa ne hydraulically. Iyo sando ine mitsetse miviri yemafuta yekugovera nekudzoka. Madhiri anomhanyisa anowanikwa mumadhayamita matatu: 90 mm, 115 mm, uye 150 mm, anokodzera zvibhorani zvine madhayamita e100–125 mm, 127–156 mm, uye 168–230 mm, zvichiteerana.

Muedzo wekuenzanisa pakati peRapid neHausherr's HBM80S pneumatic DTH drill yakaratidza kuti, kune akafanana borehole madhayamita (125 mm) nekudzika (36 m), iyo Rapid yakaratidza zvakakosha zvehupfumi zvine simba reinjini yakaderera, kushandiswa kwemafuta, uye mafuta ekuzora mareshiyo e0.46, 0.46, 0.46, uye ruremekedzo.

6. Zvikumbiro zveHydraulic Water-Powered Hammers

LKAB yeSweden pamwe nerubatsiro rwayo G-Drill yakagadzira “Wassara Mvura-Powered DTH Hammer” mukupera kwema1980. Ichishandisa mvura yemugodhi yakasefa sepakati, inoshanda nekumanikidza kwe18-20 MPa uye kuyerera kwe200-300 L/min. Neavhareji yekuboora sipidhi ye850 mm/min, inokunda sando dzepneumatic (kazhinji 320 mm/min).

Sando yeWassara yakaratidza kuita kwakasarudzika, sekudzikisa kutsauka kwechibhorani nehafu uye kuwedzera goho ne86% mumigodhi yeLKAB. Zvikumbiro zvinosanganisira kuchera metro muNew York uye kuchera geothermal kuSwitzerland, kwayakapedza chibhorani che599.8 m mumazuva mashanu, zvichienzaniswa nemavhiki matatu nemadhiri echinyakare.

7. Kuenzanisa: Hydraulic Water-Powered vs. Hydraulic Fluid-Driven Hammers

Sando-Dzine Simba: Shandisa static mvura inotsikirira, kuwana hunyanzvi hwepamusoro uye kumhanya kwekuchera, kwakakodzera kumigodhi application.

Fluid-Driven Hammers: Shandisa simba remvura kudzvinyirirwa uye rinowanzogumira pakuchera geological nedziviriro yakaderera (0.5–4 MPa) uye kunyatsoshanda (

8. Mhedziso

Hydraulic uye mvura-poweredDTH sandosanganisa mabhenefiti epamusoro-sando hydraulic drills uye pneumatic DTH sando, ichipa yakaderera simba rekushandisa, kukurumidza kuchera kumhanya, uye dzakatwasuka zvibhorani. Iyo yakabatana svikiro yemagetsi nekutsvaira inoita kuti sando dzine simba remvura dziwedzere kuvimbisa kusimudzira mune ramangwana.
