this paper discusses some of the fundamental considerations when managing mining slopes. the goal of management is to reduce all components that contribute to the geotechnical risk and by doing so reduce the risk to as low as reasonably achievable. the techniques and procedures suggested are not exhaustive; they represent a snapshot of some of the practical techniques the author has found usefu...

This paper is based on the open pit to underground mining practice of Daye Iron Mine. The influence mechanism between high-steep slope and non-pillar sublevel caving method is studied by using physical model test. Firstly, engineering geological properties of the choosing typical research section is analysed and generalized. Secondly, the system of open pit to underground mining is developing a...

Similarity search in time series data is an area of active interest in the data mining community. In this paper we introduce a novel approach for performing similarity search in time series data. This technique is based on the intuition that similar time sequences will have similar variations in their slopes and consequently in their time weighted slopes. The proposed technique is capable of ha...

the paper is concerned with the hydrogeological appraisal of the proposed mining operations in thethar lignite field in sindh, pakistan. the thar coalfield covers an area of approximately 9000km2 andcontains three lignite seams lying at depth of 130m to 250 m. in the thar lignite field, the presence ofthree main aquifers induces pore pressure in the rock mass surrounding the lignite seams and m...

The primary aim of every twenty-first century mining operation is to extract as much ore possible in a safe and economical manner. Failure mine excavation occurs when the shear stress acting on rock greater than strength mass. stability slopes open-pit quarry operations extremely important from both economic safety points view because unstable can result loss human life damage properties. This ...

The stability of mine slopes is an important factor influencing the orderly production mines and safety people’s lives property. can be effectively determined by means three-dimensional simulation analysis. Some 3D analysis methods are based on 2D analysis, still essentially methods, whereas this digital uses a true method. This method reflect overall slope in more realistic way, at same time, ...

The waste dumps resulted from the lignite exploitation activities Oltenia are constructions that reach, in most cases, impressive dimensions and store large volumes of sterile rocks. Usually, arranged ecologically restored, but between moment their release technological tasks beginning arrangement works, periods time, measured even years, can pass. calculations regarding geometry performed desi...
