A loader operator received fatal injuries when crushed within the articulation point of a load haul dump vehicle (LHD). The operator had left the cabin, with the bucket tilted backwards, whilst the engine was running. It is probable that he... Read more


New Approach Controls Dust at the Collector Dump Point

Problem The drill's dust collector dumps fine material onto the bench and generates respirable dust. The device collects dry dust from the space below the drill table that is enclosed by the shroud. This area contains respirable dust from the fine... Read more


Railway Ore Car Single Point Brake Cylinder Isolation

Problem Concern for the risk and injury associated with isolating the brakes on railway carriages to perform a brake block change out. Solution implementation of a single definite brake cylinder isolation to prevent air entering the brake cylinder and drain any air left... Read more


USING THE POINT LOAD TEST TO DETERMINE THE UNIAXIAL COMPRESSIVE STRENGTH OF COAL MEASURE ROCK

Point load testing is used to determine rock strength indexes in geotechnical practice. The point load test apparatus and procedure enables economical testing of core or lump rock samples in either a field or laboratory setting. In order to estimate... Read more


Operator Crushed In Articulation Point Of Loader

What A loader operator received fatal injuries when crushed within the articulation point of a load haul dump vehicle (LHD). The operator had left the cabin, with the bucket tilted backwards, whilst the engine was running. Why Inoperation of the engineering steering control... Read more

Pinch-point Protection for Mobile Bridge Conveyor Operators

In the past decade, 35 mobile bridge conveyor (MBC) operators have been crushed, pinched, or injured when operating an underground mobile bridge conveyor system. Most often, these accidents occurred when the miner was out of the protection of the equipment... Read more


Applications of the Point Estimation Method for Stochastic Rock Slope Engineering

Stochastic simulations of fractured rock masses can provide valuable information for the engineering design of rock slopes, particularly when the natural geologic discontinuities may form potential slope failure modes. An essential component of such engineering simulations is being able to... Read more


Mistakes, Misconceptions, and Key Points Regarding Secondary Roof Support Systems

Roof support systems are necessary to provide stable mine openings and much research has been conducted to design a variety of roof support systems that will function in various manners to ensure that stable ground conditions are achieved. Despite these... Read more
