1. Iingxaki zomgangatho kunye neziganeko
Ukudilika kodonga ngexesha lokugrumba okanye emva kokwakheka kwemingxunya.
2. Uhlalutyo lwezizathu
1) Ngenxa yokungalingani kodaka, impembelelo embi yokukhusela udonga, ukuvuza kwamanzi; Okanye iqokobhe ligqunywe lingaphantsi, okanye ukutywinwa okujikelezileyo akuxinene kwaye kukho ukuvuza kwamanzi; Okanye ubukhulu bomaleko wodongwe ezantsi kwesilinda yokukhusela alwanelanga, ukuvuza kwamanzi ezantsi kwesilinda yokukhusela nezinye izizathu, okubangela ukuphakama okungonelanga kwentloko yodaka kunye noxinzelelo olunciphileyo eludongeni lomngxuma.
2) Uxinano lodaka luncinci kakhulu, nto leyo ebangela ukuba intloko yamanzi ingaxinani eludongeni lomngxuma.
3) Xa kugqojozwa umaleko wesanti ethambileyo, ukungena ngokukhawuleza kakhulu, ukwakheka kodonga lodaka kuhamba kancinci, kwaye udonga lomthombo luphuma.
4) Akukho msebenzi uqhubekayo ngexesha lokugrumba, kwaye ixesha lokumisa ukugrumba lide embindini, kwaye intloko yamanzi emngxunyeni ayikwazi ukugcina i-2m ngaphezulu komngxuma ngaphandle komngxuma okanye umngxuma wamanzi angaphantsi komhlaba, nto leyo enciphisa uxinzelelo lwentloko yamanzi eludongeni lomngxuma.
5) Ukusebenza okungafanelekanga, gquma udonga lomngxuma xa uphakamisa i-drill okanye uphakamisa ikheyiji yentsimbi.
6) Kukho umsebenzi omkhulu wezixhobo kufutshane nomngxuma wokugrumba, okanye kukho indlela yexeshana yokuhamba, ebangela ukungcangcazela xa imoto idlula.
7) Ikhonkrithi ayigalelwa ngexesha emva kokususwa kwemingxunya, kwaye ixesha lokubekwa kwayo lide kakhulu.
3. Amanyathelo okuthintela
1) Kufuphi nomngxuma wokugrumba, musa ukubeka okwethutyana endleleni, thintela ukusebenza kwezixhobo ezinkulu.
2) Xa isilinda yokukhusela igqunywe emhlabeni, kufuneka izaliswe ngodongwe oluyi-50cm ubukhulu ezantsi, kwaye udongwe kufuneka luzaliswe lujikeleze isilinda yokukhusela, kwaye uqaphele ukuthambisa, kwaye i-backfill ejikeleze isilinda yokukhusela kufuneka ifane ukuqinisekisa ukuzinza kwesilinda yokukhusela nokuthintela ukungena kwamanzi angaphantsi komhlaba.
3) Xa ukungcangcazela kwamanzi kutshona kwisilinda esikhuselayo, isilinda esikhuselayo kufuneka sitshoniswe eludakeni kwaye singene kumaleko ngokwedatha yejoloji, kwaye umdibaniso phakathi kwesilinda esikhuselayo kufuneka uvalwe ukuthintela ukuvuza kwamanzi.
4) Ngokwedatha yophando lwejoloji ebonelelwe lisebe loyilo, ngokweemeko ezahlukeneyo zejoloji, umxhuzulane wodaka kunye nobunzima bodaka obufanelekileyo kufuneka kukhethwe ukuze kube nesantya esahlukileyo sokugrumba. Umzekelo, xa kugrunjwa kumaleko wesanti, ukuhambelana kodaka kufuneka kwandiswe, kufuneka kukhethwe izixhobo zokugaya ezingcono, kufuneka kwandiswe ubunzima bodaka ukuze kuqiniswe ukhuseleko lodonga, kwaye isantya seenyawo kufuneka sincitshiswe ngokufanelekileyo.
5) Xa inqanaba lamanzi ngexesha lezikhukula okanye kwindawo enamanzi amaninzi litshintsha kakhulu, kufuneka kuthathwe amanyathelo anjengokuphakamisa isilinda yokukhusela, ukunyusa intloko yamanzi okanye ukusebenzisa i-siphon ukuqinisekisa ukuba uxinzelelo lwentloko yamanzi luzinzile.
6) Ukugrumba kufuneka kube ngumsebenzi oqhubekayo, ngaphandle kweemeko ezikhethekileyo akufuneki kuyeke ukugrumba.
7) Xa uphakamisa i-drill kwaye uhlisa i-cage yentsimbi, yigcine ithe nkqo kwaye uzame ukungangqubani nodonga lomngxuma.
8) Ukuba umsebenzi wokulungiselela ukugalela awonelanga, musa ukuwususa umngxuma okwethutyana, uze ugalele isamente ngexesha emva kokuba umngxuma ugqityiwe.
9) Xa kubonelelwa ngamanzi, umbhobho wamanzi akufuneki ufakwe ngqo eludongeni oluvulelekileyo, kwaye amanzi angaphezulu akufuneki ahlangane kufutshane nomngxuma.
