Dr Anna Giacomini 

Whilst the Australian mining industry is recognised globally for its focus on workplace health and safety, mining personnel are challenged with risks every day. Rockfalls threaten human lives, machinery and the portal structures for underground entry located at the toe of highwalls. Such hazards can also have profound financial consequences if production temporarily stops for safety issues.

Anna has been working in Rock Mechanics and Civil Engineering for more than 12 years, having received her PhD from the University of Parma, Italy in 2003. In 2007 she joined the University of Newcastle as a research academic.  Anna has enriched her extensive research experience in rockfall analysis and rock mechanics from civil engineering to mining, adapting to her new Australian environment. As the principal researcher of an Australian Research Council Linkage Project she helped develop new designs for barriers to protect valuable infrastructure, such as roads and railways, from rock fall hazards.

Her contributions to the field have been recognised by the Australian industry as she leads three major projects through the Australian Coal Association Research Program (ACARP) on rockfall hazard and mitigation. Anna's research focuses on these hazards and their impacts in open pit mines. Together with her team, she uses innovative full scale experimental testing, novel laboratory testing techniques and advanced 3D numerical modelling to provide a rigorous and comprehensive assessment of all the major components of rockfall hazard at a given mine site.

"While each mine site is different and each highwall has different needs depending on the geological configuration of the outcropped rocks and how the highwall has been excavated, our numerical tool can be used at any mine," she explains."We can provide mines with the information they need to manage the risk of rock fall at their particular site."

"We can also give an indication of the residual hazard associated with rock fall drapery system protection measures and provide crucial information for the safe and effective design of portals and roads in open cut mines."

Within her recently honoured ACARP project Rockfall Hazard matrix for Risk reduction in mine sites, supported by Rio Tinto and Glencore, Anna and her team are extending their rockfall hazard methodology with a new Evolving Rockfall Hazard Assessment methodology that incorporates field data, current analytical and numerical tools and cutting edge research developments in rock fall hazard assessment and zoning. These results will provide greater accuracy in locating personnel, machinery, and structures across work sites, thereby improving safety and reducing the risk of interruptions in production.

While Anna's research has developed locally to understand the intricacies of the Australian environment, it is universal in scope and is potentially adaptable to many mining sites worldwide. Innovation in the mining sector cannot solely focus on technology, meaning Anna's work on processes and programs to improve safe work practices in dangerous worksites are valuable to industry and individuals.

From 2012 Anna and her team of two post-doctoral researchers and four post graduate students used advanced experimental and numerical analyses to investigate the energy absorption capacity of waste rock (muck) engineered barriers in various surface mining applications. Data provided unique worldwide experimental evidence on the effect of dynamic impacts of trucks on safety berms and useful recommendations for a safer mining environment.

This research is developing advanced numerical modelling which will allow the simulation of trucks running into windrows with a various range of velocities and approach angles (up or over 60km/hr). The outcome will provide more rigorous guidelines for windrows for haul roads enabling the mine sites to define speed limits with more confidence, and to adapt the design of windrows for various scenarios where trucks can potentially travel at high velocities.

Anna's studies were recognised by University of Newcastle in 2013, awarding her the Pro Vice-Chancellor Research Excellence Award. In 2014, she was invited to become a member of the Computer and Geotechnics Editorial board. Her global expertise has also seen her supervise international masters and postdoctoral students, become an assessor for national and international funding bodies and review international journals in the rock mechanics and engineering field.

Due to the recent improvements of automatic measurement procedures in photogrammetry, multi-view 3D reconstruction technologies are becoming a favourite survey tool. Rapidly widening structure-from-motion (SfM) software packages offer significantly easier image processing workflows than traditional photogrammetry packages. However, while most orientation and surface reconstruction strategies will almost always succeed in any given task, estimating the quality of the result is, to some extent, still an open issue. An assessment of the precision and reliability of block orientation is necessary and should be included in every processing pipeline. Such a need was clearly felt from the results of close-range photogrammetric surveys of in situ full-scale and laboratory-scale experiments. In order to study the impact of the block control and the camera network design on the block orientation accuracy, a series of Monte Carlo simulations was performed. Two image block configurations were investigated: a single pseudo-normal strip and a circular highly-convergent block. The influence of surveying and data processing choices, such as the number and accuracy of the ground control points, autofocus and camera calibration was investigated. The research highlights the most significant aspects and processes to be taken into account for adequate in situ and laboratory surveys, when modern SfM software packages are used, and evaluates their effect on the quality of the results of the surface reconstruction.

In rockfall science, the bullet effect refers to the perforation of a rockfall mesh by a small block traveling at high speed. To date, there is still no comprehensive experimental data set investigating the underlying mechanisms of such effect. The bullet effect illustrates the fact that the capacity of a rockfall mesh depends on the size and speed of the impacting block. This paper presents the results of an experimental study on the effect of block size and mesh geometry (aperture and wire diameter) on the mesh performance. The results clearly show that the amount of energy required to perforate the mesh drops as the blocks get smaller. They also suggest that the mesh performance reaches a maximum and reduces to zero when the mesh cannot sustain the static load imposed by very large blocks. The outcome of the first series validates an analytical model for mesh perforation, making it the first simple model capturing the bullet effect. A second series of tests focused on the effect of mesh geometry and it was found that decreasing the mesh aperture by 19¿% improves the performance by 50¿% while only an extra 30¿% could be gained by increasing the wire diameter by 33¿%. The outcomes of the second series were used to discuss and redefine a dimensionless geometrical parameter G* and to validate a simple power type equation relating the mesh characteristics and the mesh performance.

From a consideration of the concepts of geological weathering and structure, it can be expected that rockfall hazards should be characteristically different in different geological environments. This paper tests this idea by looking at the geometric characteristics of rock fragments formed on natural slopes in four different geological environments in Eastern Australia, where rockfall phenomena are often characterised by rolling of pre-detached debris. By measuring the three principle dimensions and making a systematic assessment of the shape characteristics of samples of rock debris in significant geological environments, it is found that the distributions of size and shape for the surface debris are statistically different. From the results, it is shown that the size and shape of debris is directly controlled by the rock type, its weathering characteristics and the structure of the parent rock mass. The severity of rockfall hazards is shown to be relatively lower in areas of Tertiary basalt, as the size of rolling fragments is limited by closely spaced fracturing inherited from its formation and the tendency to deteriorate further as it weathers deeply and rapidly. It is also lower in areas of Palaeozoic volcanics, since these tend to produce relatively angular fragments with higher proportions of fragments that are inherently more resistant to rolling. By contrast, thickly bedded sandstones form larger blocks with a larger proportion of shapes that are more prone to rolling. The size distribution of fragments is shown to be well approximated by a log-normal statistical distribution, and using the data provided in this study, it is possible to generate the size and shape data needed to undertake a stochastic assessment of rockfall trajectories in different geological environments. © 2013.

This paper investigates the factors affecting the shear strength of granular materials by means of the tilt box test. The test involves the titling of a specifically designed split-box and measuring the angle at which the upper half of the box slides off. This angle can be interpreted as the peak friction angle of the sample for a low stress state. Experimental tests and numerical analyses using the Discrete Element Method (DEM) are carried out and compared. The study is carried out for two different materials, a rounded and an angular aggregate. It is shown that rolling resistance is needed to match the experimental results if only spheres are used but this is not the case for non-spherical particles. © 2015 Taylor & Francis Group, London.

This work consists of a preliminary numerical study on the impact behaviour of rock blocks on muckpiles using the Discrete Element Method (DEM). A contact law using a linear hysteresis model for normal contacts and a Mohr-Coulomb model for tangential contacts is used. In addition, two dissipative laws are introduced consisting of a moment transfer law and normal viscous damping law. One of the aims of this study is to investigate if the contact law enables a realistic modelling of the rebound characteristics of a block during impact on a muckpile. A parametric study is carried out in order to investigate the influence of the constitutive model parameters and the presence of clumps. Numerical predictions are compared to experimental results. It is shown that clumps in the muckpile are essential to reproduce realistic results. © 2015 Taylor & Francis Group, London.

This paper presents a discrete modelling approach which allows the simulation of rockfalls behind drapery systems. The falling rock is represented by a rigid assembly of spheres whereas the slope is represented by triangular elements. Energy dissipation during impact on the slope is considered via friction and viscous damping. The drapery is represented by a set of spherical particles which interact remotely. The numerical model is used to investigate the efficiency of a drapery system. Various simulations with two different block sizes are performed and the numerical predictions of simulations with drapery are compared to simulations without drapery in order to assess the performance of the protection system.
