And because of our deep experience in the mining and minerals industry, you can be assured that these technologies are effectively deployed with a focus on improving the profitability of your operation.  

Personal dust monitoring (TEOM technology)

Particulate matter monitoring systems are used to protect miners’ health by monitoring individual exposure to dust and airborne debris.  Our personal dust monitoring systems employ tapered element oscillating microbalances (TEOM) technology and are “gravimetric” instruments that draw (then heat) ambient air through a filter at a constant flow rate, continuously weighing the filter and calculating near real-time mass concentrations of particulate matter. 


The TEOM monitor technique relies upon an exchangeable filter cartridge seated on the end of a hollow tapered tube. As particulate deposits land on the filter, the filter mass change is detected as a frequency change in the oscillation of the tube. The mass of the particulate matter is thus determined directly. When this mass change is combined with the flow rate through the system, the monitor yields an accurate measurement of the particulate concentration in real time. The major advantage of this method is that any changes in aerosol characteristics will not influence the accuracy of the mass measurement.

PDM3700 Personal Dust Monitor

Engineered for timely, high-quality personal dust exposure information, the Thermo Scientific PDM3700 Personal Dust Monitor protects miners’ health by tracking the shift-average respirable coal dust exposure as it approaches regulatory limits. Providing mine workers and management with the tools for personal coal dust monitoring and reducing their exposure, the PDM3700 real time dust monitor is the first line of defense in preventing long-term health effects.


Fugitive dust monitoring

Fugitive dust is typically created through activities such as the physical movement of soil, vehicles traveling over unpaved surfaces, heavy equipment operation, blasting, and wind. Most regions have established exposure limits on projects that typically result in high levels of particulate generation and the exposure limits are written into the operating permit.


Monitoring for fugitive dust exposure requires instrumentation that provides a quick response, is dependable, can be quickly deployed or relocated, and has the performance capabilities stated in the governing guidelines or within the site permit.  Our area dust monitors utilize highly sensitive light-scattering photometer (nephelometer) technology.  This optical configuration produces optimal response to particles, providing continuous measurements of the concentrations of airborne particles for total particulate and cut-points ranging from PM10 down to PM1, allowing operators to take immediate corrective action when necessary.

The principles of true volumetric flow, as incorporated by the ADR1500 monitor, result in an accurate sample volume and precise particle cut-point.


Coal blending technology

The advanced materials analysis instrumentation available to mining operations delivers unprecedented improvements in efficiency and profitability.  These improvements can be further extended through specialized software and informatics.  Our COBOS solution controls sorting and blending equipment with software that continuously monitors coal quality and composition.  

COBOS Coal Blend Optimization System

The Thermo Scientific COBOS Coal Blend Optimization System can blend up to six coal sources to make a "recipe" consisting of up to five quality parameters, such as ash, sulfur, moisture or even ash oxides or ratios of ash oxides. Blend recipes can be predefined for different quality targets and priorities while using fewer high cost or scarce coal resources.


Continuous emissions monitoring systems

Many mine sites utilize coal-fired power plants to produce the energy they need.  The burning of coal releases many pollutants, including sulfur dioxide (SO2) and various particulate matter. The smokestacks from these power plants also emit greenhouse gases, such as carbon dioxide (CO2) and methane (CH4), which are detrimental to the environment and health.


Continuous emissions monitoring systems (CEMS) are used to monitor these harmful substances, allowing plants to reduce emissions where necessary and meet regulatory requirements.  The system includes probes that are installed in stack and transfer gas to analyzers in the shelter.

Radiation detection

Mining industries and those that utilize mined minerals and materials as raw materials are exposed to a variety of naturally occurring radiation sources.  For example, coal contains trace amounts of naturally occurring radioactive elements. And because of the extensive use of radioactive measurement and analysis techniques (e.g. X-ray and Gamma ray analyzers) in mining operations and processing plants, the potential for exposure increases dramatically.  Both natural and man-made sources of radiation are potentially dangerous and life threatening if not managed appropriately. 


Detection of various types of radiation throughout the process is paramount to worker safety and quality control.  Radiation detection technology can be delivered by way of multiple devices, each suited for the type of radiation to be monitored, the environmental circumstances and source. 


Handheld radiation detection devices provide real time detection of gamma radiation with accurate dose rate measurements, verify the radioactive find and assess whether radioactivity is of natural or artificial (man-made) origin.

Energy Dispersive X-ray Fluorescence and Sampling Technology (EDXRF)

Energy Dispersive X-ray Fluorescence (EDXRF) is a convenient technology to screen all kinds of materials, including slurry, for quick identification and quantification of elements with little or no sample preparation. EDXRF is designed to analyze groups of elements simultaneously. This type of XRF instrumentation separates the characteristic X-rays of different elements into a complete fluorescence energy spectrum which is then processed for qualitative or quantitative analysis. Filters positioned between sample and detector are used to improve signal, background reduction, and focus on certain regions of the spectra. EDXRF instruments can have one of two types of excitation geometry; direct excitation, or 2D optics, and indirect excitation, also called 3D optics. The purpose of these geometries is to remove the background below the characteristic element lines in the spectrum and to increase the peak-to-background ratio (peak-to-noise). Both types rely on an energy dispersive detector and an X-ray tube; the difference is in the optic path.
