| Abstract: | Many kinds of method in mining rock materials has been classified in de-tail and evaluated with the theories of fuzzy sets in this paper. The key pointof technology for developing mining rock materials was proposed. Based on themechanism of blast cracking under the action of quasi-static pressure, thecracking process can be divided into three periods: crack initiation, crack pro-pagation and crack arrestment. Thus. algorithmic eguations of the judgementcriterions corresponding to three periods were given respectively. A new tech -nigue for controlling the cracking direction with two semicircle pipe holderswas also studied. Meanwhile, a new kind of explosives for mining rack materialshas been prepared and satisfied with its application. |
