Collision Avoidance: Matrix of Technologies

The first Collision Avoidance Working Group meeting that occurred on the 8th August 2006 and previous work done within Anglo American plc's divisions identified that workable technologies exist for automated detection systems that draw attention to potential collisions. It was... Read more

3D-P Proximity Detection Technology

This document gives an overview of 3D-P's proximity detection technology and products which have been developed to avoid collisions in the mining industry. ... Read more

Optimizing Secondary Roof Support with the NIOSH Support Technology Optimization Program (STOP)

The decade of the 90s brought an unprecedented increase in the development of innovative technologies to provide more effective and easier to install roof support in underground mines. To facilitate the application of these technologies to improve mine safety, NIOSH... Read more


The lack of visibility near earthmoving equipment resulted in six fatalities in U.S. surface mining operations during 2003. These accidents were the result of either a piece of equipment striking another vehicle or worker, or the equipment traveling over the... Read more

Proceedings: New Technology for Coal Mine Roof Support

The papers in these proceedings were presented at open industry briefings conducted by NIOSH on New Technology for Coal Mine Roof Support. The proceedings provide information on several important new technologies, including: guidelines for selection roof bolt length, pattern, and... Read more


This paper describes the additional features of Version 2.3, focusing primarily on the following three aspects: (1) including uncontrolled convergence into the design requirements for standing roof supports, (2) the addition of design procedures for cable bolts as an alternative... Read more

Prevalence and cost of cumulative injuries over two decades of technological advances: A look at underground coal mining in the

Technological advances in underground coal mining have led to a reduction in fatalities. This study demonstrated that the percentage of cumulative injuries remained largely unchanged across two decades of technological advances. Furthermore, the average number of lost days due to... Read more

Comparison of the depth of perception with the standard convex mirror and the M-C technology

This document illustrates the difference between standard convex mirror technology and M-C spot mirror technology visually. ... Read more

Fatigue Management: Matrix of Technologies

This document is directed at management systems, wellness programmes and automated systems that draw attention to potential collisions due to physical and/or mental fatigue of operators. It is recognised that there are some technologies/systems that could have been overlooked in... Read more

Emerging Technologies: Aiding Responders in Mine Emergencies and During the Escape from Smoke-Filled Passageways

This paper describes technology and realistic training simulations that have been identified for the general workforce and mine emergency responders ... Read more

Field Evaluation of Mobile Roof Support Technologies

This study presents a historic overview of the role of mobile roof support (MRS) technologies in improving stability and worker safety and presents the results of recent field evaluations of the MRS load rate monitoring device and other remote deformation-monitoring... Read more

Neural Network Technology for Strata Strength Characterization

The process of drilling and bolting the roof is currently one of the most dangerous jobs in underground mining, resulting in about 1,000 accidents with injuries each year in the United States. To increase the safety of underground miners, researches... Read more

Proceedings: New Technology for Ground Control in Retreat Mining

abstracts from nine papers presented describing several new highly practical technologies developed by NIOSH, Pittsburgh, and Spokane Research Centres to improve safety during pillar retreat operations ... Read more

Product Recall: City Technology 4CF Carbon Monoxide Sensor

Hazard: A faulty Carbon Monoxide Sensor may no longer respond to the presence of carbon monoxide. Cause: A failure mode has been identified in this sensor. It may show as an unexpected, catastrophic loss of sensitivity, inhibiting the sensor’s ability... Read more

Safe and Cost Effective Repair Using Composite Technology

Presentation given to the OIM/SUP network meeting 18 Nov 2004 on Composite Repairs Guidelines following the recent concerns in the industry covering: Introduction of workgroup; epair design (including lifetime, service conditions); Qualification issues; Installation (what is critical); NDT (how and...

Mine Rescue Training Simulations and Technology

Reports on a series of mine rescue training exercises developed, conducted and evaluated by the National Institute for Occupational Safety and Health (NIOSH) in cooperation with the Pennsylvania Department of Environmental Protection, Bureau of Deep Mine Safety ... Read more

Emerging Technologies and the Future of Geotechnical Instrumentation

This paper discusses the results of two recent case studies in which high-tech prototype instruments were used. The first case study describes the results of a ground-based hyperspectral imaging tool used to map the geology of an open-pit mine highwall.... Read more

Forecasting Roof Falls with Monitoring Technologies - A Look at the Moonee Colliery Experience

There has been a persistent need to forecast roof falls so that miners exposure to hazardous underground environments can be minimized. Several monitoring techniques have been developed and are used today with varying levels of acceptance in the mining industry.... Read more

Hydraulic Prestressing Units: An Innovation in Roof Support Technology

A new generation of hydraulic mine support prestressing devices has been developed. These thin-walled steel shells are machine-welded and can be inflated with water or any liquid to provide prestressing for a wide variety of roof support products ranging from... Read more

Mapping Hazards with Microseismic Technology to Anticipate Roof Falls - A Case Study

As the amount of new fractured surfaces or damaged rock layers within roof rock increases, the stability of the rock mass decreases. While direct measurements of this phenomenon are not easily made, there is good circumstantial evidence to support this... Read more
