Abstract (en)
[origin: EP2476994A1] The blasting method (1) involves introducing a borehole (9) into a rock layer (5), which runs in a predefined angle to a vertical axis (V) and introducing another borehole (11) in the rock layer, which runs in another predefined angle (beta) to a horizontal axis (H). The latter borehole is stand in fluidic connection with the former borehole. The liquid is discharged by the latter borehole. An independent claim is also included for an assembly for two boreholes in rock layer.
