PROCESS OF BLASTING OPERATIONS Russian patent published in 1998 - IPC

FIELD: mining industry, construction. SUBSTANCE: process of blasting operations includes blasting of family of charges, registration of vibrations of ground and check of parameters of blasts in family. Increased reliability of process is achieved due to provision for check of number and parameters of blasts of single charges in family. Blasts of single charges in family are carried out with moderation interval equal or exceeding period of least low-frequency component of vibrations of ground generated by blast. Check of parameters of blasts of charges in family is realized by way of analysis of results of registration of vibrations of ground with isolation of each blast by emergence of forward waves and amplitudes. In agreement with another version period of least low-frequency component of vibrations of ground generated by blast is determined by blasting of single shaped charge and registration of emerging vibrations. EFFECT: increased reliability of process.
