I-Goldcorp, i-opharetha yemayini esebenza emhlabeni wonke, ingumvukuzi omkhulu wegolide enyakatho-mpumalanga ye-Ontario. Eduze kwedolobha lase-Chapleau e-Ontario, eCanada, inkampani yenza amadiphozithi amasha egolide afinyeleleke nge-Borden Gold Project.
Ukumbiwa kwephothali kanye nokwakhiwa kwerempu yokufinyelela kuqale ngekota yokuqala yowezi-2017. Kuzokhishwa isampula yenqwaba ye-30,000t ukuze kuqinisekiswe ukuba khona kwamadiphozithi egolide kule mayini yamatshe aqinile.
Ngisho nangaphambi kokufinyelela kule ngosi, i-DSI Underground Canada yakha ingxenye yekomiti lezobuchwepheshe ukuze lisize ekuthuthukisweni ngokushesha kwemayini. Onjiniyela be-DSI Underground abanolwazi bahlongoza ezinye izixazululo ezindleleni ezijwayelekile zokwesekwa komhlabathi. Ukusekelwa okujwayelekile kwe-resin kanye ne-rebar esetshenziswa enyakatho yeCanada bekuzokwandisa isikhathi sokuqalisa ngenxa yemikhawulo yamazinga okushisa aphezulu.
Ngenxa yalesi sizathu, imayini yanquma ukusebenzisa i-DSI Hollow Bar Anchor njengomkhiqizo osebenza kahle wokusekela umhlabathi ukuze kuqinisekiswe ukuthuthukiswa okusheshayo kwephothali. I-DSI Hollow Bar Bolt ifakwe kusetshenziswa ama-rotary drill air noma aqhutshwa ngamanzi, okuqinisekisa amazinga aphezulu okufakwa kanye nokuzinza okuhle kokuqondisa. Ngaphezu kwalokho, inhlabathi engaphakathi kwe-borehole iyahlanganiswa.
Nge-resin grout, ukusetshenziswa kwayo okungaba yinkinga ngenxa yesimo sezulu esingalindelekile, umqondo uwukudala ukusekelwa okusebenzayo kwephasi yokuqala ngokuqinisa ibhawodi ngegobolondo eliqukethe i-rock mass ekucindezelekeni. Ngale ndlela, ama-bolts angahlungwa ngedethi ezayo. Manje, enye indlela yokonga isikhathi nentsha yalolu hlelo iyatholakala: Uhlelo olusha lwe-DSI Underground, olumpompayo lwenhlaka. Le ndlela iqinisekisa umjikelezo wokuthuthukiswa okusheshayo. Ngenxa yokusebenzisa lolu hlelo lwe-resin, iMayini ye-Borden izokwazi ukushayela ingosi ngokushesha ngokuphepha, futhi ifinyelele ngokuphumelelayo isampula yenqwaba.
