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
Simplified Hyperspectral Imaging for Improved Geologic Mapping of Mine Slopes
A prototype portable hyperspectral imager that operates in the visible and near-infrared ranges of the electromagnetic spectrum was field tested at an open-pit mine. The tests were sponsored by the Spokane Research Laboratory, N IOSH, as part of an investigation... Read more

Catalogue of Support Documents for the NSW Mine Health and Safety Legislation
This Catalogue of Support Documents provides a road map to published material to help industry better understand matters covered by health and safety legislation in relation to mining work in the metalliferous, extractives and opal mining sectors. ... Read more
Mine Surveying and Drafting
This standard provides a way for Mine Surveyors to comply with section 67 of the Coal Mining Safety and Health Act 1999 and the relevant sections in the associated Regulations. It is to be followed by all Mine Surveyors, and... Read more
Fatal Natural Gas Ignition, Dial's Branch. Pinsonfork, Kentucky. U.S.A.
What A front-end loader bucket penetrated a 20-inch diameter, high pressure, public utility, natural gas transmission line. The front-end loader became engulfed in flames resulting in serious burns to the loader operator. The victim died Why Excavation work done near gas transmission lines... Read more
Report of Investigation - Fatal Underground Coal Mine Fire
What On Thursday, January 19, 2006, an underground mine fire occurred near the longwall conveyor belt drive. Miners working underground began evacuating the mine. Heavy smoke was encountered by the 12 miners who were evacuating from the development section located inby... Read more
SHEC Corporate Management System Standard: Development of a SHEC Risk Register
The purpose of this Standard is to: Define the process for identification, broad risk rating and review of site SHEC risks; Prescribe the development of a site SHEC Risk Register that lists, for each business sub-process, the significant hazards, the... Read more
Safety Improvements at Chandala Laboratory
Problem The Tiwest Laboratory at Chandala analyses pre-production drill hole samples using heavy media separation. Most of the work involved is in the sample preparation stage of drying, splitting and wet sieving of clay/sand samples. The target output rate resulted in... Read more

A front-end loader bucket penetrated a 20-inch diameter, high pressure, public utility, natural gas transmission line. The front-end loader became engulfed in flames resulting in serious burns to the loader operator. The victim died. Excavation work done near gas transmission... Read more
Fatal Fall-of-Roof Accident, No. 55 Mine. Keystone, West Virginia. U.S.A.
What A continuous-mining machine operator was fatally crushed when a horseback in the roof fell without warning Why An undetected slickensided horseback was undermined and fell. The approved roof-control plan was not being followed Recommendations Approved mining projections should be followed at all times. Provide... Read more
STOCKPILE AND SURGEPILE SAFETY RECOMMENDATIONS
Where feeders are used to draw material from under a pile, physical indicators should be installed to show mobile equipment operators the exact location of these feeders. Maps showing relative location of feeders is not adequate for safety purposes. In... 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
Field-Scale Void Detection in Coal Piles Using Resistivity Imaging
To reduce fatalities resulting from personnel falling into voids formed above feeders in coal piles, NIOSH established a project to monitor coal surge piles to detect the formation of voids. A resistivity imaging method has been developed by GECOH Exploration,... Read more
Large-Scale Strata Response to Longwall Mining: A Case Study
This U. S. Bureau of Mines report summarizes a study of large-scale strata response to longwall mining at a western U.S. coal mine. This study utilized surface and subsurface measurements, geologic mapping, in situ stress measurements, and pressure cell readings... Read more
Mechanics of a Large, Strain-Type Rock Burst and Design for Prevention
Detailed mapping and examination of the site of a large rock burst at the Lucky Friday Mine, Mullan, ID, demonstrated conclusively that damage was caused by a splitting and buckling failure mechanism initiated by separation of rock into layers along... Read more
A Portable Spectro-Polarimetric Imager: Potential Mine Safety and Geologic Applications
A significant risk factor in assessing and modeling potential catastrophic slope movement in open-pit mines is the presence of argillic alteration in host rocks. High resolution hyperspectral imagery operating in the visible to shortwave infrared can be a useful tool... Read more
Fatal Fall of Roof Accident, NEWCO No.1 Mine, Sunrise Coal Company, LLC, Jefferson County, Alabama, I.D. No. 01-03102
What A 28-year old mobile bridge operator was fatally injured when a roof fall occurred Why The accident occurred because the operator did not recognize the presence of a drag fold (horseback) and failed to comply with provisions of the approved roof control... Read more
Fatal Underground Coal Mine Fire
What On Thursday, January 19, 2006, an underground mine fire occurred near the longwall conveyor belt drive. Miners working underground began evacuating the mine. Heavy smoke was encountered by the 12 miners who were evacuating from the development section located inby... Read more
Fatal Ignition Accident
What A bulldozer operator was fatally injured while cutting a bench in the natural slope of a hillside in preparation for surface mining. The accident occurred when the blade of his bulldozer ruptured a buried 16-inch, low pressure, high volume, natural... Read more
