Abstract (en)
[origin: EP0897098A2] A method and system for causing a multi-shot blast is disclosed and claimed. According to the method, suitable positions for detonators 14.1 to 14.8 are determined in situ. Position related data (x;y) is determined automatically for each position utilizing a GPS system and also identification code data of each detonator. This data is transferred to a controller 16 via a data-capturing device 18. The controller establishes a blast programme including inter hole delay times calculated by taking into account the position related data, geological structure, hole depth, mass of explosive in hole etc. The controller transmits signals including delay time data to the detonators, to cause them to detonate according to the programme.
