【 摘 要 】
The technique for determining geometric parameters of cracks formed in rock mass under penetration of a hard tool is presented. The results of rock fracture as impact craters and main cracks formed in a marble block after penetration of a wedge-shaped steel tool are discussed. The photographs of the craters and polished sections of drill cores are given.
