DRILLING PRE-PLANNING IMPORTANT
Drilling is the creation of Artificial cavity into rock for the placement of Explosive. Drilling can be done for different purpose ranging from: 1. Rock Blasting 2. Oil and gas production 3.rock stability and Safety purpose 4. Exploration purpose 5. Water and borehole drilling 6. Among others. Drilling for rock Blasting is done for the loading of Explosive into the rock formation so as to generate the shock and gas energy require to fragment the rock mass. Planning for an event makes the event or operation more perfect and productive. The condition of the drill holes and arrangements in place of pattern design of the hole drilled for Blasting has great impact on the effectiveness of the blasting. Some of the parameters that explains the status of blast holes are: 1. Burden: the perpendicular distance between the first drill holes row to the nearest free face. Or in others way, the distance between two adjacent Hole rows.this affect distribution of energy wit...
