problem 1: Monitoring of blasts is undertaken for a variety of reasons, discuss why this is the case. Describe briefly the methods of blast monitoring available and their range of application.

problem 2: Define the following:

• Paddock blasting
• Cushion blasting
• Decoupling
• Lifters
• Easers
• Primer
• Throw blasting

problem 3: Describe the methods of controlled blasting that are available and their range of applicability.

problem 4: Summarise the technique of designing tunnel blasts outlined in the notes. Particular attention should be focussed on the equations employed and the methodology employed in the quadrant technique.

problem 5: Describe with the aid of diagrams typical blasting rounds for shaft and raise development.

problem 6: Blasting and mechanical excavation of rocks are the most common methods employed in mining to break rock. What other methods are available?

problem 7: Safety is a prime concern in the use, storage and handling of explosives. Briefly describe how safety has been improved since the first use of explosives in mines and outline the steps you would take to ensure the safe use, storage and handling of explosives at a mine site.

problem 8: Using explosives in sulphide ores and in hot reactive rock poses certain difficulties, what are these and what steps can be taken to minimise their impact?

problem 9: When loading explosives by pouring or by pneumatic loading an earthing cable is employed, why is this?

problem 10: Describe an electronic system of blast initiation. What are the safety advantages of this system?
