Controlled Blasting
- Licensed shotfirers
- DGMS rules
- Blast design per bench
- Vibration monitored
There is no such thing as an approximately correct shot.
Load too much explosive and stone travels where stone was never meant to go. Load too little and you are left with a toe, boulders the loader has to pick over one at a time, and a breaker running all week to save the price of a few cartridges. Take no account of what is standing within a few hundred metres and the consequence stops being technical: a complaint first, then a notice, then an officer from the district standing on your bench.
Our shotfirers hold licences and work to DGMS rules. Each round is drawn up for the face it will be fired into. Last week's design is a place to start, never an answer.
What we bring to the site
- 01
Licensed and documented
Shotfirer licences, magazine licence, a written handling procedure and a movement register accounting for every cartridge issued and every one returned. All of it is in place and open to inspection before the first box reaches site.
- 02
Designed for the bench
Burden and spacing set against the rock and the face height, stemming column measured rather than eyeballed, delay sequence chosen for the fragment size the crusher wants to be fed. Timing is where fragmentation and vibration are both settled.
- 03
Overburden and rock excavation
Loosening rocky overburden so the seam underneath can be worked, and taking down ground a hydraulic breaker would still be chipping at a month later, having cost many times as much.
- 04
Vibration and the neighbours
Peak particle velocity recorded at the nearest structure, exclusion zones marked and cleared before the countdown, and a condition survey of the buildings around the boundary taken in advance rather than argued about after a crack appears.
Blasting questions
01Is your blasting licensed?
It is. Rounds are fired by licensed shotfirers to DGMS rules, the magazine is licensed, and the explosive movement register is kept on site rather than in a drawer at head office. Bring your safety officer and audit the lot.
02We have houses near the boundary. Can you still blast?
Usually yes, but the constraint drives the design rather than the other way about. Charge per delay comes down, the sequence tightens, and you fire more rounds to shift the same volume. Per cubic metre that costs more than an open bench standing in empty country. It costs far less than being shut down.
03Can you blast on our site with our licence?
It turns on the scope of the licence and the names written on it. Send the document across and we will give you a plain yes or no in writing, which beats discovering the gap on the day the explosive is due at the magazine.
Usually goes with
Drilling Services
Ten rigs with compressor backing. Every hole collared where the pattern puts it, drilled to the depth and inclination the pattern asks for, and logged.
Mining Operations
Bare ground to a working face: overburden off, benches cut, rock down and moving. Twenty excavators, and crews who have opened a face before rather than read about it.
