Section 50 Disposition versions

2018-09-20

50. Where, during drilling or the blasting of a shotpoint, groundwater flows to the surface or where the presence of gas is detected, the authorization holder must

(1)  interrupt the shotpoint drilling work in progress;

(2)  make sure that no explosive charge is placed in adjacent shotpoints during the drilling; and

(3)  stop the water or gas flow by sealing the shotpoint so that the fluid is confined in its initial zone, with a material that ensures an impervious and durable sealing.

Where the drilling of a shotpoint is completed and the explosive charge is already inserted when groundwater flows to the surface or the presence of gas is detected, the holder must blast according to the procedure provided for in the technical program before stopping the water or gas flow by sealing the shotpoint in accordance with subparagraph 3 of the first paragraph.

To continue drilling work, the holder must move or reduce the depth of the drilling of adjacent shotpoints to prevent new groundwater flows to the surface or another gas kick.
