Book Description
Sensing and Monitoring Technologies for Mines and Hazardous Areas: Monitoring and Prediction Technologies presents the fundamentals of mining related geotechnical risk and how the latest advances in sensing and data communication can be used both to prevent accidents and provide early warnings. Opencast mining operations involve huge quantities of overburden removal, dumping, and backfilling in excavated areas. Substantial increases in the rate of accumulation of waste dumps in recent years has resulted in greater height of dumps and also has given rise to the danger of dump failures as steeper open pit slopes are prone to failure. These failures lead to loss of valuable human lives and damage to mining machinery. This book presents the most recent advances in gas sensors, methane detectors, and power cut-off systems. It also introduces monitoring of the gas strata and environment, and an overview of the use of Internet of Things and cloud computing for mining sensing and surveillance purposes. Targeted at geotechnical and mining engineers, this volume covers the latest findings and technology to prevent mining accidents and mitigate the inherent risk of the activity. Presents complete details of a real-time slope stability monitoring system using wireless sensor networking and prediction technique based on multivariate statistical analysis of various parameters and analytical hierarchy process methods Discusses innovative ideas and new concepts of sensing technologies, mine transport surveillance, digital mining, and cloud computing to improve safety and productivity in mining industry Includes slope stability prediction software, downloadable through a companion website, which can be used for monitoring, analyzing, and storing different sensors and providing audio-visual, SMS, and email alerts Covers the latest findings and technology to prevent mining accidents and mitigate the inherent risk

Book Description
The growing needs have been pushing the limits, to which the mining industry has to reach to lift itself to fulfill the demand. The effect can be seen from the methods of mining that have evolved over the years. The heavy machinery adopted for the extraction has been producing wastes in the form of waste rocks whose management is again of prime importance. The issues relating to the stability of these overburden dumps is catching attention worldwide from quite some time, which is quite important for the safe working in and around these monstrous structures as well as restricted availability of land. This paper deals with the stability issues of dumped slopes for a local chromite mine. The analysis cover analysis of various sections of the waste dumps from the mine including material properties, strength values, bench height and angle.

Book Description
Stability of underground excavations is of great importance to an operating mine because it ensures the safety of the working people and operating equipment, and successful ore production. Due to the complex geological conditions and mine constructions, and variability and uncertainty in estimating rock mass mechanical properties, the assessment of rock mass stability for an underground mine is extremely challenging and difficult. Tackling of this difficult problem is not covered in detail in any of the textbooks currently available in the rock mechanics literature. This monograph aims to cover this gap in the rock mechanics and rock engineering field. This monograph provides detailed procedures for the stability assessment and support design for an underground mine case study. It covers the background of the mine site including the monitored deformation data, the state-of-art methodologies for the stability analysis of rock masses around underground excavations, performed laboratory tests, estimation of the rock mass properties, a brief theory and background of the 3-D Distinct Element Code (3DEC), and numerical modeling of underground rock mass stability including investigation of the effectiveness of rock supports. The monograph is an excellent reference for the senior undergraduates, graduate students, researchers and practitioners who work in the Underground Rock Mechanics and Rock Engineering area in the Mining Engineering, Civil Geotechnical Engineering and DEM (Distinct Element Method) Numerical modeling.

Book Description
An attempt is made to place before students (degree and post-degree) and professionals in the fields of Mining Engineering, Geology and Earth Sciences this important problem of stability and capacity optimization of existing Internal Dumps in opencast coal mines. With same recipe external dump slopes can be analyzed. It deals various phases of internal dump stability in a lucid style with live case studies. Book covers a wider spectrum - determination of composition of material & physico-mechanical properties, plasticity and their effect on stability. Stability analysis of existing and optimized dumps by older & modern methods helps in identifying change in stability. In some of the cases, stability has improved in optimized dumps. Further, effects of plasticity of dump material on stability and identification of compound failures have been discussed. This helps in establishing norms and location of dump stability monitoring.

Book Description
Mining methods have changed and grown to fulfill extractive demands. Heavy machinery is used to extract overburden in open pit and open cast mines and to create waste dumps prone to slope stability issues. As the heaviest equipment operating on dump locations, mine haul trucks require a safe, stable surface to work on, so the stability of waste dumps is hugely important. Slope failures frequently occur on mine cut slopes, embankments, dumps, and road cut surfaces, so an improved understanding, monitoring, and support of such slopes is important to prevent failure, loss of equipment and fatalities. One of the most important differences between waste dump slopes and other slopes such as embankments or road cuts is not only that waste dumps are made up of loose face dumped material but also goes that trucks impact cyclic loads which affect stability. For example, significant weight at hundreds of tonnes has a huge impact on slope stability. This cyclic loading scenario on mine waste dumps has yet to be investigated fully. This study looks at the stability of waste dumps under the impact of mining equipment based on physical modeling (laboratory scale tests), numerical modeling and "Slide" slope stability software. During the study on the stability of waste dumps by physical modeling, data related to rolling resistance was also recorded. It has been concluded that the results from both the physical and numerical modeling determined acceptable states for truck path by both truck location for the chosen test material, Dolomitic limestone (1/3 and 1/2 truck width from crest), and constructing a safety berm along the crest of slope, and for wet conditions.
