We are extremely proud to announce that MST has been chosen by Hochschild Mining Group to be their mine communication partner in for their mines throughout Latin America.

Hochschild is modernizing and expanding their operations to optimize safety and increase production in their mines. As such they had identified improved underground mine communications as a vital enabling technology to help meet their corporate goals. On this basis Hochschild went out to competitive tender seeking a partner with extensive mining communication skills and technologies. Hence we were very honored to be chosen by Hochschild after their extensive international search into mining communications.

The range of MST’s communication technologies was a deciding factor as MST is able to provide a range of complementary technologies to provide overall communication solutions to their mining operations.

The initial technology implementations will underground two-way communications provided by the VDV Leaky Feeder Radio System. The VDV system are being installed at the following mines:

Aracata Mine in Peru; is installing a VDV System consisting of a 5 Channel VDV Headend, 19.6 km (64,000 ft) of radiating leaky coax antenna cable, 3,000 m (9,800 ft) of non-radiating cable, 54 Infinity Line Amplifiers, 7 Branches (both 2 & 3 way versions) , plus full system diagnostics and telephone PABX interface.

Selene Mine in Peru; is also installing VDV Leaky Feeder with a 5 Channel Headend, 4.2 km (14,000 ft) of leaky coax antenna cable, 13 Infinity Line Amplifiers, 3 Branches (both 2 & 3 way versions) , plus full system diagnostics and telephone PABX interface.

San Jose Mine in Argentina; this VDV System will cover the two mines at this with the single 5 channel Headend. The underground distribution has 2.8 km (9,200 ft) of radiating leaky coax antenna cable and 4,500 m (14,800 ft) of non-radiating cable. This cable infrastructure incorporates 13 Infinity Line Amplifiers with full system diagnostics and telephone PABX interface.

Pallancata Mine in Peru; a new development, this mine requires 1,100 m (3,600 ft) 4 Infinity Line Amplifiers, 1 Branch, plus full system diagnostics and telephone PABX interface on their 5 channel Headend.

VDV Line Amps are small and extremely robust for mine use

MST’s leaky coax cable connectors simplify installation and maintenance

Volcan Compania Minera have purchased another leaky feeder radio system from MST, this time for their Cerro de Pasco Mine in Peru.

Volcan had purchased two VDV Leaky Feeder Radio systems earlier this year for their Yauli – Andayhagua and Yauli – San Cristobal mines, so we are very pleased to received this vote of confidence in our leaky feeder technology for Cerro de Pasco Mine. The system is larger than the first two installations, consisting of:
- 9 Channel Headend
- 56 Line Amplifiers
- 19.8 km (65,000 ft) of leaky coax antenna cable

The system will provide extensive two-way radio coverage underground on the main travel ways and in the working areas.

Again, we are very grateful for this continuing support shown by Volcan for our underground communications.

VDV Radio System Headend

We are very pleased to announce the purchase of VDV Leaky Feeder Radio Systems by two mines from Volcan Compania Minera in Peru.

We have supplied VDV equipment into other Peruvian mines in the past, but these two installations represent our first complete system orders into Peru. Despite competition from other leaky feeder suppliers, VDV was chosen as it offered superior performance and, most importantly due to extreme physical conditions in the Peruvian mines, the highly ruggedized and sealed Infinity Series Line Amplifiers have a record for long term reliability.

The first mine isYauli – Andayhagua MIne with the first stage of the installation consisting of a 2 Channel Headend powering 44 Infinity Series Line Amplifiers in 14.6 km of leaky coax antenna.

The second mine is Yauli – San Cristobal & Carahuacra Mine. This is used to establish radio communications into a complete new area of the mine and consists of 36 Infinity Series Line Amplifiers and 10.8 km of coax antenna.

We are very grateful for the support shown by Volcan for our leaky feeder technology and the opportunity is presents in accessing further mines in Peru.

FIRST VDV LEAKY FEEDER SYSTEM IN CHILE

MINE: PUNTA EL COBRE
OWNER:
TYPE: UNDERGROUND COPPER
LOCATION: CHILE, REGION III

BACKGROUND

Punta el Cobre wanted to introduce a radio system to streamline all aspects of their underground operation. Despite a very competitive biddign process, MST’s VDV Leaky Feeder system was chosen as it menat the rigorous technical specifications for the sytem.

COMPOSITION

• VDV Headend driving 11 km of leak coax antenna with 28 Lime Amps.

DESCRIPTION

The 11 km system is composed of 28 amplifiers distributed along the main ramp and two main branches, allowing the communication to the upper and lower levels in the mine. Also, the system has two communication channels for control in production, performance and supervision of internal and external development of the mine. Two antenna towers on the surface, at the Tunnel Ramp and Trinidad Exit, provide communication to all offices, and all routes into and out of the mine to the mill. The underground communications system was designed to provide for the future development and advance of the the mine over the next 3 years. This will mean at least another 5 km of leaky coax will be added to the system. Also, the system uses our latest diagnostic system. This allows the performance of all amplifiers underground to be constantly monitored and, should a problem arise, the location and nature of the problem is immediately known.

JUSTIFICATION

The prime justification for the radio system was to enhance the management systems at the mine through the use of a mutli-channel radio system.
