Open Pit Mining through Underground Workings : Guideline
This MOSHAB approved guideline describes the hazards that occur when open pit mines encroach on land previously mined by underground methods. Hazard identification includes the need to review previous mine plans over the area to be worked and risk analysis... Read more
Vertical Opening Safety Practice in Underground Mines: Guideline
This MOSHAB approved guideline identifies some of the hazards associated with vertical openings within or into underground mines and recommends procedures to avoid or minimise these hazards. The relevant legislative requirements for Western Australia are covered in detail. The ore... Read more
Safety Bund Walls Around Abandoned Open Pit Mines : Guideline
This MOSHAB approved guideline has been issued to assist mining companies with the design of safety bund walls around abandoned open pit mines in order to minimise potential risks to the public. The legislative requirements for Western Australia are described... Read more
Personnel Transport: Safe Seating Arrangement for Passengers Transported on Open Vehicles
The Anglo American Safety Golden Rule No 4 requires of Operations that Seat Belts are installed and worn by all occupants when vehicles are used in surface activities. Some of the vehicle fleets used at Operations were purchased some time... Read more
Fall Restraint - Protecting People Working Near Excavations and the Open-pit
Problem Fatalities due to falling from heights, specifically highwalls and open-pits. Solution An Adjustible runout rope, fixing system and portable anchor (vehicle) Benefits Eliminates risk of a fall, functional, simplistic, practical and easily accepted and transferable thoughout workforce. ...

Reducing Musculoskeletal Risk in Open Cut Coal Mining
The objectives of the project were: (i) to identify and assess common high risk manual tasks involved in open cut coal mining; (ii) to develop, implement, and evaluate control measures for these tasks; and (iii) to determine whether controls are... Read more
Geotechnical Considerations in Open Pit Mines
A guideline for the general compliance of Mines Safety and Inspection Regulations within Western Australian. Regulation 13.8 as reference information related to Geotechnical considerations. Also life of mine plan, rock support and reinforcement, pit wall design, monitoring and... Read more
Guideline for the Use of Explosives in Open Cut Coal Mines
This guideline aims to assist in the development and management of a system to use and store explosives at mine sites in New South Wales, and to control shotfiring operations. It describes a shotfiring and explosives management system, covering record... Read more

Towards best practice in open-pit mining
Cerro Vanguardia, situated in the Santa Cruz province in Argentina, is unique among AngloGold Ashanti's surface mines because of the nature of the ore occurrence. The gold-bearing ore occurs in vertical veins up to 10 metres thick, which average 3.5... Read more
Assessing and Monitoring Open Pit Mine Highwalls
Slope stability accidents are one of the leading causes of fatalities at U.S. surface mining operations. The Spokane Research Laboratory of the National Institute for Occupational Safety and Health (NIOSH) is currently conducting research to reduce the fatalities associated with... Read more
Computer Modelling of Catch Benches to Mitigate Rockfall Hazards in Open Pit Mines
A computer analysis of bench stability has been developed to account for multiple occurrences of potential slope-failure modes in discontinuous rock masses. Bench-scale plane shears and tetrahedral wedges are simulated and stochastically analyzed to estimate the probability of retaining specified... Read more
Effects of Far-Field Shearing Deformation on Fracturing Around an Underground Opening
Researchers at the National Institute for Occupational Safety and Health (NIOSH) are investigating the causes and mechanisms of roof failure in underground mines. It is expected that a better understanding of these causes and mechanisms will lead to better layout... Read more
STABILITY OF UNDERGROUND OPENINGS ADJACENT TO THE SINK HOLE AT THE NIOSH LAKE LYNN RESEARCH LABORATORY
Over a portion of the older limestone mine workings at the NIOSH Lake Lynn Laboratory, a mining health and safety research facility, a large sinkhole formed caused in part by the intersection of several tightly spaced joint sets and unusual... Read more
A study of the ground control effects of mining longwall faces into open or backfilled entries.
Unusual circumstances may require that a longwall retreat into or through a previously driven room. The operation can be completed successfully, but there have been a number of spectacular failures ... Read more
Open Pit Scaling
What Three contract drilling employees and a contract geologist were lucky to escape serious injury when approximately 150 tonnes of rock fell from the pit wall above them. Why The fall was caused by a wedge failure along two intersecting joints in the... Read more
Guidance on brake testing for rubber-tyred vehicles operating in quarries, open-cast coal sites and mines
This booklet contains guidance for brake testing self-propelled, rubber-tyred vehicles such as those used in quarries, at opencast coal sites, on mine surfaces or underground in mines. The guidance may also be useful in other industries where similar vehicles are... Read more
Guidelines for Surface Mobile and Transportable Equipment for use in Coal Mines
A guide to the design of mobile equipment to be used at open cut coal mines, the surface of underground coal mines and around coal processing plants. Important safety aspects covered in this guideline include control functions, ergonomics, mechanical and... Read more
Truck driver fell from deck of Caterpillar 777D haul truck - fatal accident
What During normal haul truck operations at an open pit mine, a female operator was found on the ground at a location directly below the access ladder to the driver's deck of a Caterpillar 777D haul truck. The truck was stationary... Read more
