The prediction of rock sawability is very important in the cost estimation and the best planning of the plants. Rock sawability depends on the machine characteristics and rock mechanical properties. In this study, a new classification was developed with the respect to rock mechanical properties such as Uniaxial Compressive Strength, Brazilian tensile strength, Schmidt hammer value and Los Angeles abrasion loss. Using this system the carbonate rock sawability index (CRSi) of several types of carbonate rock was evaluated and classified into five categories and then a new model was developed with the respect to CRSi and machining characteristics by using the statistical analyses for predicting the production rate of circular diamond saws in carbonate rock cutting. With the sawability classification and developed model, it is very convenient to evaluate the sawability for a new carbonate rock type and predicting the production rate for a new factory by only the practical mechanical testing.
Prognozowanie urabialności skał jest niezmiernie ważne z punktu widzenia oceny kosztów i najlepszego rozplanowania kopalni. Urabialność skał związana jest z ich skrawalnością i z ich właściwościami mechanicznymi. W pracy tej przedstawiono nowy system klasyfikacji skał w oparciu o ich właściwości mechaniczne, takie jak jednoosiowa wytrzymałość na ściskanie, wytrzymałość na rozciąganie, wytrzymałość w oparciu o test brazylijski, twardość określana według odpowiednich testów, ubytki wskutek ścierania. W oparciu o powyższy system, obliczono współczynnik urabialności skał węglanowych dla kilku rodzajów skał zaklasyfikowanych następnie do pięciu kategorii; następnie opracowano nowy model dla obliczania urabialności i skrawalności skał w oparciu o analizę statystyczną, umożliwiający przewidywanie postępów urabiania skał przy wykorzystaniu okrągłych pił diamentowych. W oparciu o przedstawiony system klasyfikacji oraz opracowany model możliwe jest prognozowanie urabialności nowych skał węglanowych oraz prognozowanie dziennego postępu prac w nowej kopalni za pomocą praktycznych badań mechanicznych.
