Published paper: The Relationship Between Elemental Carbon and DPM
This paper focusses on the relationship between Total Carbon (TC) and Elemental Carbon (EC) and how the former is used as a surrogate to help determine diesel particulate exposures.
Ventsim 4 Announcement
Note the “LiveVIEW Asynchronous Data Collection” feature. Pinssar’s interface picks up particulate samples from its data repository and automatically displays them in LiveVIEW.

Mining, Safety and Prevention Review: Final Report (Ontario, Canada)
Increased levels of monitoring toxic substances
Investment in safety
Safety is the driving force behind European technology investment
National emission standards for non-road diesel engines
International law firm Ashurst published the attached Environmental Alert that summaries the current state of play regarding legislation and supporting codes of conduct and guidelines as it pertains to non-road diesel engines. There is specific reference to underground mining on page 2.
Improving communications using sensors
NSW Work Health & Safety Legislation
The legislation can be reviewed in full at these sites:
Work Health and Safety (Mines) Act 2013
Work Health and Safety (Mines) Regulation 2014
They come in to force 1st February 2015.
- There is a move towards greater integration amongst the needs of coal and metals operators
- The new legislation is based on the national model regulations and is another step towards harmonisation particularly with both Queensland and Western Australia
- Controls such as air quality monitoring, the use of explanatory signage, and diesel exhaust monitoring are highlighted
The toolbox talk refers to ISO 31000, the principles relating to ALARP, the use of decision-making tools, and bow-tie processes.
The Case for Innovation in the Mining Industry
His paper focusses on a range of technology and how it could be applied to increase efficiency and productivity in the mining sector.
Safe Work Australia: Australian Work Exposures Study: PAH (November 2014)
PAH (Polycyclic Aromatic Hydrocarbons) or simply hydrocarbons are found in fossil fuels and mainly produced when there is insufficient oxygen available during the combustion process inside a diesel engine. They have been identified as carcinogens and mutagenic having the potential to have adverse health effects.
Production Energy Optimisation in Mining
The authors refer to mine operational costs and how 15-40% of these costs can be attributed to energy consumption. They review processes (for example, the Plan-Do-Check-Act model), tools and technologies available to potentially reduce energy expenses. References are made to the various sensors on the market and how HMI user-interfaces and dashboards play a role.
Real-time monitoring and optimisation in underground mines
This paper investigates the viability of implementing a “mine production real-time optimisation” (MPRTO) system. It reviews different optimisation theory, communications system (leaky feeder and data networks), emissions, safety and health, ventilation control, planning and scheduling, and capital expenditure considerations.
Ontario, Canada. Revised diesel engine exhaust test
The test is based on reading CO (carbon monoxide) from the exhaust. It is largely derived from an incomplete combustion process. CO is colourless and odourless and toxic to humans above levels of 35 ppm but must be measured against the ratio of oxygen available.
Ontario: Canada. Ministry of Labour – Mining Health and Safety Prevention Report
A number of working groups have been established. One of these working groups will investigate the introduction of new technology and the need for adequate change management resources to be allocated to any deployment to ensure the technology is successfully implemented.
Pinssar ships the first sensor that continuously monitors DPM
Pinssar’s Ambient Air Monitoring System “Reader” was designed as a networked sensor measuring mass concentrations of sub-micron particles at regular intervals. This parameter is a useful surrogate measurement of diesel particulates in underground mine environments.
Western Australia: modernisation of safety legislation

NIOSH Center for Direct Reading and Sensor Technologies (NCDRST)
With the deployment of wireless communications in underground mines, remote sensors are playing an ever increasing role harvesting data for analysis, and supporting timely decision making. NCDRST was established May 2014, and is focussed on occupational safety and health. This initiative is aligned with Pinssar’s Ambient Air Monitoring System’s aims and ambitions.
