Easy, Quick & Fast Substitute of Conventional knotting between Detonating Cord and Shock Tube.
The conventional knotting process between Detonating Cord and Shock Tube is a difficult and time taking activity and it becomes challenging for the miners to immaculately execute the knotting process under high workload and harsh environmental conditions of the mining sites. Due to high workload it is not always possible for the miners to knot together the Detonating cord and shock tube exactly at right angle to each other ; a mandatory requirement for successful initiation of shock tubes.
J.HOOK | CONVENTIIONAL KNOT |
Economy of Time ( 50-60 % Time saving)
Max 2-3 seconds per assembly 20-30 blast holes per minute . |
Min 5-6 seconds per knot
10-12 blast holes per minute. |
One point and exactly 90° angle connection between Detonating cord and Shock Tube , mandatory for successful initiation | Humanely Not always possible to make 90° angle connection ,increasing the chances of misfires. |
No chance of tube cut off due to one point and 90° angle connection | Chances of tube cut off when the tube comes close to Detonating cord at any point other than knot. |
No chance of loose knot, as the Detcord and shock tube automatically sets in its proper positions. | Chances of loose knot as the force applied on every knot varies from knot to knot and man to man. |
