CURRENT TECHNOLOGIES

There are various backbone technologies to enable voice and data to be transported to the surface and displayed on its monitoring and control system.

Leaky Feeder Radio Systems (VDV)

Wi-Fi based Systems

Flexible voice and data communications infrastructure that is robust and easy to deploy ,that can provide redundancy during the harsh construction stage.


VDV Leaky Feeder Radio System

Provides a high quality, two way voice communications to underground projects. The leaky coax antenna allows the use of a variety of digital and analogue radios from all major radio manufacturers, such as Tait, Motorola, iCom, Kenwood and others.

The productivity and safety benefits associated with a VDV installation make it a cost effective solution to your underground communication requirements

Tunnel VoIP PhoneMobile VoIP telephones can be integrated into the site IP PBX phone system, providing seamless communications for site operations.

Tracking TagsLightweight, rugged tags have 2.4GHz transmitters and 125 kHz receivers with internal antennas, and are designed for harsh tunnel operations and environments.

Electronic TagboardUsing Access Control, always know who is in or out of the tunnel at all times.

Emergency Call PointHighly visible, vandal resistant unit, designed for simple one button operation, and to connect to a control room or supervisor phone.

Composite CableSpecially made composite cable that includes optic fiber cores (for data) and coper cores (for power). This simple concept with connectors at each end make the network a true “plug and play” solution.

Electronic Tagboard vs. Traditional Tagboard

▪ Traditional brass tag tagboards can compromise tunnel workers’ safety and reduce productivity

▪ Electronic Access Control at each entrance and exit displays workers in/out of the tunnel on an Electronic Tagboard screen

▪ Access control and the Electronic Tagboard provide automated reporting of employee and subcontractor time in/out of the tunnel

Electronic TagboardMST Access ControlTraditional Tagboard

Tracking of Personnel, Vehicles, and Equipment

▪ Tunnel dashboard software provides superior situational awareness, with real-time positioning of personnel, vehicles, and equipment on a map

▪ Wi-Fi tags are lightweight, rugged, & designed for harsh environments

▪ Tunneling activities can be monitored to identify operational issues

▪ Quickly take measures to minimizedowntime and avoid bottlenecks

▪ Automate access and surveillanceof dangerous areas with “geofences”

▪ Around heavy machinery,

▪ Areas with dangerous gases

▪ Unsecure areas, etc.

Proximity Detection

MST proximity solutions:1. Inner Zone Only2. Inner Zone + Outer Zone

VENTILATION

Reduce energy and maintenance costs by adding a Responsible Ventilation system.

Utilizing monitoring and control systems, the location of personnel and equipment in the mine can be determined and utilized to create zones to control the auxiliary fans of the ventilation system. This fully automated system utilizes tagging and tracking components to determine the real-time location of personnel and mobile equipment and idle fans in areas where miners and diesel machines are not present.

Emergency Call Point vs. “Break Glass” Alarms

▪ False emergency evacuations cost job sites hundreds of thousands of dollars each year

▪ Example: A site has 12 emergency evacuations (break glass events) per year and only 20% constitute real emergencies. Each evac costs an average loss of six production hours (evac time, validate emergency, return to work time). With 100 workers this represents cost of $18k per incident, or nearly $200k/year (100 workers x 6 hrs x $30/hr = $18k)

▪ With the Emergency Call Point

▪ Press the EMERGENCY button

▪ Call is routed to supervisor phone or control room

▪ Determination made to evacuate or to send aid

▪ Supervisor or control room can remotely activate the full evacuation protocol (sirens, strobes, instructions)

TBM Guidance, Video Surveillance, Gas Monitoring, etc.

▪ Underground and surface fiber optic networks provide a highspeed data highway for all construction and subcontractor needs

▪ Guidance and Tunneling Process Control data for TBM’s

▪ Video Monitoring through the Security Centre

▪ Remote ventilation control and ventilation on demand

▪ Use of Tablets for Engineers and Supervisors

▪ Fixed IP Phones for permanent operations

▪ Automated environmental monitoring (O2, CO, NO, NO2, SO2, H2S & Tempurature)

▪ Vehicle Intelligence Platform (VIP) for vehicle telemetry

▪ Call direct to any user

▪ Push-to-talk to any user

▪ Use up to 24 channels

▪ Initiate an emergency broadcast

▪ Make calls to outside telephones

MST Wireless Sensor Network (WSN) provides a wireless mesh extension to our core ImPact Network to provide a easily deployable, highly reliable data link to remote sensors and transducers. A common application is to stream data from Geotechnical monitoring sensors back to the mine’s network without the need for any data or power cabling.
