When busy mine operations intersect the local community
Since commencing operations in 2018 this central Queensland coal mine has been gearing up production and mining operations, now moving coal 24 hours a day with as many as three trucks per hour doing a round trip between the mine and the train loadout facility.
Impact of mine traffic on the township
The 75km round trip involves the haul trucks collecting coal at the mine site, travelling along the dirt access road, joining the main highway, passing through the local township, driving on to the rail loading facility then returning empty via the same route to the mine for the next load.
During peak times heavy-duty trucks leave and enter the public highway as often as every 15-20 minutes making the management of site access a high safety and security priority.
Secure Coast Solutions customised access control system has it covered
Secure Coast Solutions designed an access control system with two key objectives in mind:
- to maximise the safety of the general public, and
- to maintain the efficiency of mining operations.
Considerations for protecting the public
- The bi-directional dirt road that enters the mine site is restricted for use by haul trucks and mine employees. Preventing unauthorised people driving down the mine access road is a priority.
- The mine operators had obtained special permits allowing passage via the highway and through school zones. As the trucks run 24 hours a day, to minimise the impact on the local community, restrictions on the frequency of operations are in place depending on the time of day.
Considerations for maximising haul road traffic efficiency
- If the trucks had to stop each time they enter and exit the mine sites this would have a significant impact on haulage efficiency – increasing travel time, fuel usage as well as wear and tear on the vehicles.
- For the haul trucks to be able to access mine areas without stopping they had to be able to open the boom gates automatically before approaching the control point and automatically close behind them.
- Being dirt roads meant safety loop detectors weren’t suitable and if the road became muddy in the rain PE beams couldn’t be used either.
- In addition to the haul trucks, access was required for maintenance and other mine personnel.
- The location of the boom gates at the entrance to the loadout facility meant power was unavailable.
- For safety and vehicle management mine operators wanted to be able to monitor the location of all trucks along the haulage route.
Efficient Practical Solution in Action
- Boom Gates were installed to prevent unauthorised vehicles from entering mine access roads.
- To allow the haul trucks to pass unhindered through the boom gates they were fitted with long-range RFID tags. When a truck is within 10-15 meters of the boom gate, long-range readers mounted on card reader stands, detect the tags on the bull bar of the haul truck and opens the boom gate.
- Radar safety devices hold the boom gate open as the trucks pass when the radar is clear the boom gate automatically lowers a few seconds later.
- Rotech’s dual height card reader stands allow entry and exit for light and large vehicles not fitted with tags.
- If a truck doesn’t reach its destination within an hour after leaving the mine site the boom gate control system sends an alarm to the control centre. The mine control centre monitors the location of each truck and other traffic. Communications are achieved using 4G routers providing internet access over the mobile phone network.
- Accommodating for varying traffic flows depending on the time of day and for weekends, the Bionik AG automatic boom gate’s multi-function digital controller made set up and programming of the access control system easy.
- Six 120W solar panels were installed to provide power for the entire system. Adding 720amp/hours of battery storage means the solar panels can provide enough power for 4-5 days allowing for overcast weather.
- LED strip lighting on the boom gate arms and illuminated card reader posts provide increased visibility and safety during night works.
Why the Bionik AG Boom Gate was the best choice for the job
“This is a busy, intensive use situation requiring high levels of safety and reliable operation. The Bionik AG boom gates are low in maintenance, fast to activate and are robust and reliable.
LED lights illuminate the boom arms and the electronics are inside a well sealed enclosure protecting the components from coal dust.
All equipment chosen is 100% duty cycle and high temperature rated so it can be used as often as needed. The Bionik AG Automatic Boom Gate featured everything needed to do the job.”

Mansfield State High School – Not Your Average Construction Site
With 2800 students currently enrolled and expectations for this to soar to 3,000 in 2020, Mansfield State High School has embarked on a significant expansion of its facilities to accommodate current and anticipated future growth.
Student safety during construction
Health & Safety is always a top priority during any construction project but never is this more important than during a build in an active school environment.
The new multipurpose hall being built on the school grounds presented a significant safety challenge for the developers:
- 2,800 students needing access to the sports field
- many loads of materials and heavy machinery requiring access around the edge of the sports field to get to the construction site.
As a new build, the groundwork was a key aspect of the project and requires a lot of heavy machinery. Additionally, construction deliveries, are a frequent and unavoidable part of any construction project. Eliminating risk isn’t easy.
Rotech was tasked by specialist access control company Que Access to provide a temporary safe crossing for students and teachers while facilitating Contractor access/exit requirements from the street to the construction site.
Boom gates pair up to manage traffic flow
An intelligent automatic boom gate system was installed by Que Access to manage vehicle and pedestrian access where they intersect.
Pedestrian access was controlled by two Bionik AG Automatic Boom Gates fitted with a fence on each pole to prevent students from ducking underneath. Under normal circumstances, the pedestrian access boom poles remain open allowing students/teachers to move freely in and out of the sports field.
Vehicle access is also controlled by two Bionik AG Automatic Boom Gates which remain in the closed position until activation. Construction traffic travels along a temporary fenced roadway, on reaching the pedestrian access gates the driver pushes a button to gain entry through the intersection.
Automated Access Procedure
When construction vehicles reach the pedestrian access gates the driver pushes a button which initiates the following automated procedure:
- Red LED lights flash on the pedestrian boom pole and a siren sounds a warning to pedestrians that the gates are about to close
- 15 seconds later, if all students/teachers have cleared the intersection, the pedestrian access boom gates close
- Safety PE beams prevent the vehicle access gates from opening and closing if there is any obstruction such as a person in the intersection.
- Once pedestrian gates are fully closed the vehicle access boom gates automatically open allowing traffic to move through the intersection.
- When pedestrians are clear of the pathway an electrical interlock sends a signal to the controller to close the vehicle access gate.
- Once the intersection is empty and the vehicle access gate is fully closed the pedestrian access gate re-opens.
- The LED lights turn green indicating the intersection is safe for students/teachers to pass through.
The automatic boom gates were mounted on 20 mm thick steel base to keep them stable while allowing for relocation when required.
