ab0cd Sub-sectoral Environmental and Social Guidelines: Mining Open Cast Mining Underground Sub Sector Environmental & Social Guidelines Page 1 PROCESS DESCRIPTION This guideline covers the open cast mining of ore bearing rock including coal. It excludes quarrying and open cast extraction of construction materials, stone and rock. (The
an aquifer affecting the stability of a slope in an open pit mine is a very efficient means of dewatering. The main advantage is a relatively low installation cost, no energy consumption for water discharge and low maintenance cost. TECHNICAL ASPECTS OF OPEN PIT MINE DEWATERING 485
Geotechnical Considerations in Open Pit Mines Version 1.0 Department of Minerals and Energy Page 4 of 49 2.0 LEGISLATIVE REQUIREMENTS (WA) The Mines Safety and Inspection Regulations 1995 contains regulations (in Part 13), that apply to the geotechnical considerations that must be adequately considered during the
Draperies directly act on the stability of the blocks, but also control their fall should failure occur. Such systems are common practice within Australia open pit mines. In surface mining, draperies are used to prevent rock from impacting directly onto the concrete covers used .
Slope stability is a major problem in opencast mines. Slope stability in a large scale open pit mining operation is a matter of concern for the mine management so as to establish safety throughout the life of the mines. Again the profitability of the open pit mines is dependent to a large extent on the use of steepest pit slopes possible ...
The open pit or open cast mining method is the obvious choice for a property with a wide area of mineralization exposed or existing close to the surface and continuing to greater depths. The open pit exposes the orebody from the surface by separate removal of ore and associated waste rocks.

SLOPE STABILITY ANALYSIS FOR OPEN PITS José L. Carvalho Golder Associates Ltd., Mississauga, CANADA 1.0 INTRODUCTION In the process of wall design for open pits, a number of steps and levels of analyses are required, from local bench design to overall stability of the walls, to evaluation of the design performance and
In engineering projects associated with rock mechanic science like open pit mines, assessment and slope sta- bility of mine walls is one of the important performance in generate of these structures. Estimating and knowledge of stable slope angle is one of main parts that should be occurring to special attention in open pit mines studies phase.

Surface mining includes mechanical excavation methods such as open pit and open cast (strip mining), and aqueous methods such as placer and solution mining. Underground mining is usually classified in three categories of methods: unsupported, supported, and caving.
May 06, 2011· To enable the redesign of failed slopes and the planning and design of preventive and remedial measures, where necessary. To study the effect of seismic loadings on slopes and embankments. Aim of slope stability: Safe, properly designed, scientifically engineered slope. Profitability of open cast mines.
Mechanized open-pit mining of old barite diggings began in 1924 to recover barite left behind by hand mining, and washing plants were used to clean the clay from the barite. Hand mining, however, continued to thrive, and washer plants began to close temporarily in 1931; nearly all of the barite produced before 1937 was by hand mining.
realized by the mine. Slope stability monitoring at Letlhakane mine Mining activities whether by open pit or underground methods bring about volumetric as well as stress and strain changes in the rock mass around a mine opening. Once deformations exceed the limits controlled by the rock strength, instability is created around the mining excavation.
