Abstract:

Since blasting is a comminution process, the feasibility of establishing a correlation between the Bond rod mill work index (kWh/t) and some easily measurable physico-mechanical properties relevant to blasting was investigated. Further, the concept of operating blast work index and its potential applications were explored. Four different rock types and a well documented case study of two blasts were selected for this study.<br>The work index is found to be uncorrelated with the density and unconfined compressive strength, slightly related with tensile strength, and well correlated with dynamic

Abstract:

<p> Case histories in mining have long described pillars or faces of rock failing violently with an accompanying rapid ejection of debris and broken material into the working areas of the mine. These unstable failures have resulted in large losses of life and collapses of entire mine panels. Modern mining operations take significant steps to reduce the likelihood of unstable failure, however eliminating their occurrence is difficult in practice. Researchers over several decades have supplemented studies of unstable failures through the application of various numerical methods. The direction of

Abstract:

Rockbursts may cause damages to underground openings and to equipment, and constitute a major hazard to the safety of mine workers. One method that can be used to evaluate if there is a rockburst potential is to compare the stiffness of the failed rock with that of the surrounding rock mass. This method has been applied successfully in the past to rockbursts involving fracturing of the rock mass.<br>This thesis deals with the development of a similar approach for rockbursts involving a violent slip along major geological discontinuities. To evaluate the post-peak shear stiffness of a discontin

Abstract:

Recirculation of air is a widely used technique in general ventilation and air conditioning practise.<br>Interest in the application of controlled recirculation of ventilation air in mines has grown considerably in the last decade. This is evident by the number of controlled recirculation schemes which have been implemented or are being considered or planned in several countries and in different types of mines.<br>A detailed description is given of the operating and proposed schemes in South African gold and U.K. coal mines. This includes safety, dust filtration and blast contaminant removal s

Abstract:

As humanity prepares to migrate to the frontiers of the Moon and other planets, the area of mining in space must go along for the purpose of exploration and in-situ resource utilization. In the present work the literature that has been developed over the years in the area of mining in space as applicable to Lunar and Martian environments is reviewed. Subsequently, the key mining technologies that are most suitable for Lunar and Martian environments are identified. From the literature review, it is concluded that an optimal combination of both mechanical methods and novel energy (lasers,

Full text

Abstract:

Wheel loaders are widely used in mines, construction projects, and waste processing fields due to their merits of high mobility, remarkable operational flexibility, and relative low capital cost. Automatic control of the loading process will achieve high productivity, solve the problem of shortage of experienced operators, release human workers from hazardous working environments, and reduce maintenance cost associated with machine abuse. Existing research on wheel loader control only automate the manipulator mechanism while leave the locomotion system to human operators. The research in this

Abstract:

Assessing long-term rock stability is an important aspect in the analysis of slopes, dam and bridge foundations, and other infrastructure. Rock behavior over tens to thousands of years must be anticipated when predicting the performance of, for example, an underground containment facility for nuclear waste. At such long time scales, the time dependence of rock failure, typically ignored in short time scale analyses, has a significant effect and must be included in the analysis. Since time-dependent rock behavior is thought to be caused by the subcritical growth of microcracks, a time-depend

Full text

Abstract:

Rock reinforcing elements provide a significant proportion of their ground control capability through offering resistance to shear movement of adjacent rock masses or blocks. This potential shear movement may take the form of sliding on horizontal bedding planes leading to strata bending; or block displacement along other geological structures such as joints or similar discontinuities. Much has been reported about this type of behaviour of rock bolts and other tendons, in theoretical concepts. However, there is a shortage of quality data available on the exact nature of this mechanism for shea

Abstract:

Earthmoving is a common activity at mines, construction sites, hazardous waste cleanup locations, and road works. Expensive and sophisticated machines such as front-end-loaders (FEL), backhoe loaders, LHD loaders and front shovels are used for these excavation tasks. Autonomous excavation control for these machines has gained considerable attention in order to remove human operators from hazardous environments, improve productivity and utilization, reduce machine abuse, as well as decrease machine operating costs. However, automatic control of excavation tasks for many sites that require diggi
