Hand Drilling Teams
JSB also provides a professional hand drilling and blasting service for secondary breaking and reef removal on opencast mines.
Hand drilling equipment can often be readily taken to sites which larger, more conventional drilling cannot access. Services can be rendered at a daily rate or on a monthly contract.
The marking, drilling, charging up and blasting operation will be performed by JSB personnel, whilst explosive products have to be supplied by the customer. The blaster on site will be both RBC (Rock Breaking Cartridge) and Conventional certified, allowing the client to undertake sensitive blasting where necessary. This provides a highly affordable solution since evacuation of personnel and equipment is not necessary.
Advantages of using hand drilling teams:
- Larger mobility than drill rigs
- Small diameter holes provide more effective breaking, better control and guaranteed fragmentation
- Drilling can be done in areas inaccessible to rigs
- Significantly more cost effective than rigs
- Selective and accurate breaking can be achieved
JSB clients making use of the hand drilling service include:
- MCC Open Cast Mining Contractors
- Murray & Roberts (Concor)
- Petnim Ltd
