Method for explosion free blasting of materials such as stone and concrete, involves filling exploder mass predominantly on basis of unslaked limestone so that explosion effect occurs by heat development and explosion pressure

摘要

#CMT# #/CMT# The method involves filling exploder mass (4) predominantly on the basis of unslaked limestone so that explosion effect occurs by the heat development and explosion pressure. The exploder is mixed with water. A pressure safety is formed in the bore hole for an explosive device by increasing the bore hole roughness in a filling area (94) or by enforcing or inserting an explosion plug or by a valve-like closure body. #CMT# : #/CMT# An independent claim is included for an explosive device for explosion free blasting, particularly of stone and concrete. #CMT#USE : #/CMT# Method for explosion free blasting of materials such as stone and concrete. #CMT#ADVANTAGE : #/CMT# The exploder is mixed with water and a pressure safety is formed in the bore hole for a explosive device by increasing the bore hole roughness in the filling area or by enforcing or inserting an explosion plug or by a valve-like closure body, and hence ensures a safe blasting of materials. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of an explosive device. 1 : Stone block 4 : Exploder mass 85 : Ball 91 : Base 94 : Filling area.
