Dynamaster®

Acoem blast monitoring system

Accurate blast monitoring improves blasting efficiency and helps organisations comply with environmental and occupational health and safety regulations. A robust and reliable monitoring system is integral to achieving 100% data capture and obtaining results immediately after each blast event.

The automated Acoem blast monitoring system includes a network of remote blast monitoring stations, made up of Dynamate® units. Dynamate® stations are supervised by our remote software package — Dynamaster® — which lets you view blast results, produce reports and interact with the server software via its web browser.

Dynamaster® is installed on our Acoem server and maintained at Acoem Australasia headquarters in Melbourne, Australia. It continuously communicates with Dynamate® stations and users online.

Features

Fully integrated system – ability to trigger all units from one event

100% blast capture* due to histogram search facility with "after the event" searches and data capture. [*capture rate as of Sep 2015].

Continuously records (500 or 1000 Hz) over pressure signals in an endless sample buffer loop independent of other software processes

At the maximum sample rate, the buffer stores up to 10 days of air blast and vibration data.

Six weeks of data storage

Results available via SMS and/or email to authorised users within minutes of the blast and can be downloaded from a secure website for further processing.

Timely access to data

Assess breaches in exceedance levels, perform test triggers to check conditions before proceeding and no minimum downtime between capture events.

No need for 'Line of Sight’ considerations

Units can be located anywhere that has available communication networks, with major carriers guaranteeing coverage in 99% of locations for reliable high-speed data transfer.

Data security on the go

Results and data are only available to authorised users and can be downloaded or viewed anytime at work, home or on the road.

Blast capture

Each Dynamate® has a dynamic triggering program built into its software which allows you to identify one or more Early Warning Units (EWUs), usually those closest to the blast epicentre, to act as the trigger source for other units. The dynamic triggering system also determines vibration and air blast sources to avoid false triggers caused by other blasts nearby.

Blast events can be triggered via several methods:

Manual: by the Dynamaster® user
Threshold: when air blast or vibration levels exceed a user-defined threshold
External: generated by another Dynamate® station or compatible device
Auto: Dynamate® continuously generates event files covering a user-defined period
Integral: you set a threshold limit, but the software determines whether it’s an actual blast or a single peak caused by another phenomenon, such as rock fracturing.

Blast results are automatically collected from the stations, collated and made available within minutes of the blast.

With a ‘set and forget’ approach, once the unit is placed in the field and switched on, data triggered by your specified parameters — for example, air blast exceedances at a Dynamate® station or a low battery warning — is sent via GPRS, 3G or 4G communication to a central server where it’s uploaded to the website and sent to users by SMS and/or email accessible on any enabled device. Other communication methods such as satellites can also be employed.

Components

The Dynamates® Blast Monitoring System consists of:

Battery management module
Optimises the battery by monitoring battery temperature, state of charge, available solar power & current power consumption
Air blast (-3dB < 2Hz) microphone & windscreen
Designed to dramatically minimise the effect of wind on air blast readings & ensure accuracy of readings
Triaxial geophone
Used as the ground vibration transducer (SM6-4.5 Hz or HS-1-LT 2.0 Hz piezo geophone or piezo electric accelerometer)
Sealed lead acid (SLA) battery
Eliminates the effects of spillage and out-gassing, which are common problems with ‘wet’ batteries
Comprehensive gas emissions plan
Can be integrated into both blast/vibration monitoring and dust monitoring programs to manage gaseous fumes, particularly Carbon Monoxide (CO) and Oxides of Nitrogen (NOx).

Applications

Whether the project is above or below ground, on a construction, demolition, mining or quarry site; accurate blast monitoring improves blasting efficiency and helps organisations comply with environmental and occupational health and safety regulations.
