Emjikelezweni weminyaka eyi-10, noma ngabe "i-Tianjin Qianli" noma "i-Longtop Mining", izibophezele ekuhlinzekeni amakhasimende omhlaba ngemikhiqizo engcono yezimayini yezimayini engabizi kakhulu, okuhlanganisa, kodwa kungagcini lapho, amathuluzi okumba amatshe womoya akhiqizwa ifektri yakho.
Ngo-2022, sasungula inkampani entsha, i-Tianjin Rioto Machinery, ezobhekana kakhulu nebhizinisi lokuthekelisa le-Tianjin Longtop Mining. I-Tianjin Longtop Mining Co., Ltd izoqhubeka nokuba khona futhi ibe nesibopho kwamanye amabhizinisi enkampani. Ngethemba ukuthi wonke amakhasimende angaqonda futhi asekele.
Kule minyaka engu-14 edlule, ngokubambisana namazwe ahlukene kanye nezifunda zamabhizinisi ezimayini, abathengisi bemishini kanye nolwazi oluqoqiwe, singanikeza amakhasimende ulwazi olufika ngesikhathi futhi olunembile lwemboni kanye nolwazi lomkhiqizo; Ngokwezidingo ezihlukene zamakhasimende ukuhlinzeka amakhasimende ngemikhiqizo namasevisi asebenza kahle kakhulu futhi anesilinganiso senani lentengo.
Imikhiqizo namasevisi ayinhloko manje esingawanikeza amakhasimende ethu:
1.Imishini yokumba izimayini kanye namathuluzi asekelayo kanye nemishini
2.Imishini yokufaka umoya emayini (ayikwazi ukuqhuma futhi ingaqhumi)
3. Imishini yokukhipha amanzi emayini (amaphampu angaphansi kwamanzi, iphampu ye-diaphragm)
4. Ukukhanyisa kwezimayini (izinhlobo ezahlukene zezibani zemayini)
I-5.Imishini yezokuthutha yezimayini (izinhlobo ezahlukene ze-winch yokuthutha, i-scraper, iloli yokulahla, njll.)
6.Imikhiqizo yokuphepha yezimayini
Sibheke ngabomvu ukusebenzisana namakhasimende ethu kule minyaka eyishumi ezayo ukuze siqhubeke nokudala inani elikhulu kumakhasimende ethu ngemikhiqizo namasevisi wethu wekhwalithi.
