Into ebizwa ngokuba yi-coal-water slurry ibhekisela kwi-slurry eyenziwe ngamalahle angama-70%, i-29% yamanzi kunye ne-1% yezongezo zekhemikhali emva kokuvuselela. Isisibaso solwelo esinokumpontshwa kwaye sifakwe inkungu njengeoyile yamafutha. Inokuthuthwa kwaye igcinwe kwimigama emide, kwaye ixabiso layo le-calorific lilingana nesiqingatha seoli yeoli. Isetyenzisiwe kwiibhoyila eziqhelekileyo ezibaswa ngeoyile, iziko lenkanyamba, kunye neziko lokulayishwa ngokukhawuleza kwekhonkco. Xa kuthelekiswa negesi yamalahle okanye ukunyibilika, indlela yokucocwa kodaka lwamalahle ilula, utyalo-mali luncinci kakhulu, kwaye ixabiso nalo liphantsi, ngoko ke ukusukela oko yaphuhliswa phakathi kwiminyaka yee-1970, iye yatsala umdla wamazwe amaninzi. ilizwe lam lilizwe elikhulu elivelisa amalahle. Ityale imali eninzi kulo mmandla kwaye ifumene amava atyebileyo. Ngoku kunokwenzeka ukwenza i-high-concentration-coal-water slurry ukusuka kumgubo wamalahle oveliswe ngokuhlamba amalahle.

Izongezo zekhemikhali zodaka lwamanzi amalahle ngokwenene zibandakanya izinto ezisasaza, izinzisi, i-defoamers kunye nezihlwayo, kodwa ngokubanzi zibhekisa kwiindidi ezimbini ze-disapersants kunye nezizinzi. Indima yesongezo kukuba: kwelinye icala, amalahle acoliweyo angasasazwa ngokufanayo kumbindi wamanzi ngendlela yesuntswana elinye, kwaye kwangaxeshanye, kuyafuneka ukuba enze ifilimu ye-hydration phezu kobuso bomhlaba. i-particle, ukwenzela ukuba i-slurry yamanzi amalahle ibe ne-viscosity ethile kunye ne-fluidity;
