Gas Monitoring System

Deltamation designs and manufactures a Tube Bundle system for use in Australian underground coal mines to monitor and record underground gas levels. All components included in Delta Automation Tube Bundle System are specified to comply with Australian and Department of Primary Industries standards.

Tube Bundle System Key Features

• Designed from the ground up to comply with AS 3000 & NSW Coal Mine Regulations
• Emerson analyser provides high accuracy, fast response and long term stability
• All major components mounted on front panel for ease of viewing
• Rotameters on all tubes to allow for flow balancing and monitoring of each individual tube
• Low volume flow path to allow for low purge time between samples
• All electronic components either have a suitable IP rating, are in an IP 65 enclosure or are installed in the communication hut
• Supplied with high efficiency, high flow rate purge pumps to allow for high flow rates from the mine, leading to lower time delay from samples points
• The System is set to measure standard mine gases, but also can be configured with a GC to detect and record other gases such as Hydrogen, Ethylene, Ethane, Acetylene
• Standby sample and purge pumps supplied connected and ready to operate to allow for rapid recovery time in the event of a pump failure
• Ethernet connection to analyser to allow for remote access for high level remote diagnostics
• System can be supplied with IP cameras to allow remote monitoring
• Check valves fitted on each line to prevent air ingress back into the tubes
• System was designed in consultation with experienced ventilation officers as well as DII personnel to maximize functionality while ensuring compliance with standards

Tube Bundle System Design

• The system is made up from two separate buildings, one that houses the gas analyser and instrumentation whilst the other contains communication and control equipment
• A standard gas hut is made from mesh and colourbond sheeting to provide natural ventilation and security against unauthorized access, while still ensuring the compliance with Australian and NSW Mines Department requirements
• Emerson X-Stream process gas analyser is used to deliver high accuracy gas readings. The X-stream measures up to four components in various combinations, and its versatile design allows physical benches to be installed in their own compartment, separate from the electronics.
  In addition to X-Stream gas analyser, Emerson Gas Chromatograph can be installed to assist with monitoring of trace gases in the mine. Typically the GC would be setup to measure trace levels of hydrocarbons
• All control and monitoring components are mounted on the front panel and include vacuum and sample pump pressure transmitters with displays as well as a flow controller to ensure a regulated flow of gas independent of tube resistance
• The calibration gas connection facilitates easy calibration of the analyser by simply a click of a button. To monitor system stability, test gas cylinders have been designed to be included within the sample gas sequence
