Design of openpit mining SlideShare
Pit designGeneral design parameters and planning data• Density of seams, total coal column thickness•Thickness of partings• Gradient• Geological disturbances• Strike lengths, shape of property• Geological Reserves• Surface constraints/adjacent habitat• Dump yards availability with lead and lift• Mining system, optimum mining Open pit mining The ores in an open pit mine are covered by overburden Both the ores and overburden are removed in benches ranging from height 9 m to 30 m A thin deposit may require one or few benches but a thick deposit needs more number of benches and the pit in its production stage resembles like an inverted cone 4 4 Design Open pit mining SlideShare • Mining cost modelling, mining capex and opex • Reserve statement Subtopics, incorporated into the value chain, discussed during the course will include the following: • Key factors to consider in pit design and design criteria • Modelling techniques and calibration • Drilling and blasting for stable pit walls • Mine water risk in OpenPit Mine Planning and Design University of Pretoria Open pit mining • Open pit mining is the process of mining a near surface deposit by means of a surface pit excavated using horizontal benches 5 The shape of the excavation or mine vary depending upon the size and shape mineral matter 6 WHEN TO ADOPT OPENPIT MINING Open pit mining SlideShare Introduction 12/14/2014 3 In open pit mining : Any overburden is stripped and transported to a disposal area to uncover the mineral deposit Both stripping and mining are from one or a sequence of benches Openpit mines are used when deposits are found near the surface Open pit mining Open pit mining SlideShare
OPEN PIT MINE PLANNING: ANALYSIS AND SYSTEM
planning and design processes employed by surface mining oil sands operations vary in distinct ways from other commodities mined by both hard and soft rock open pit methods The unique waste handling needs, including tailings disposal, of contemporary oil sands mining requires specific planning considerations Geotechnical Considerations in Open Pit Mines Version 10 Department of Minerals and Energy Page 3 of 49 10 INTRODUCTION The potentially hazardous nature of open pit mining requires the application of sound geotechnical engineering practice to mine design and general operating procedures, to allowGEOTECHNICAL CONSIDERATIONS IN OPEN PIT MINES Abstract: Planning and design procedure of an open pit mining project just can be started after ultimate pit determination In the carried out study in this paper it was shown that the most important factor in ultimate pit determination and in consequence in the whole planning and design procedure of an open pit mine is the metal priceDETERMINATION OF ULTIMATE PIT LIMITS IN OPEN haulage roads in the open pit mining problem need to connect the pit exit to The shortcut (in This article has presented a solution for the open pit ramp design problem(PDF) Optimum ramp design in open pit mines Deswik Delivering Mining EfficiencyDeswik Delivering Mining Efficiency

The higher productivity for open pit mining equipment also lowers costs The necessary underground equipment for maintaining productivity is more expensive on a unit basis capacity than corresponding open pit equipment Furthermore, the large production scale and share number of open pit mines have provided the opportunity for manufacturing design A design reliability of 80% is generally accepted in open pit design, which means allowing 20% of all wedges actually to fail The accepted failure level determines the design bench angle In the following example, DIPS is used to interpret the structural data and identify the joint sets for theSLOPE STABILITY ANALYSIS FOR OPEN PITS 1surface miningppt工程科技专业资料 采矿工程专业英语 Mining Engineering English 姓名：陈 璐 2、Surface Mining pit limits Open pit slope bench slope toe berm slope angle crest Benchsurface miningppt图文百度文库 istration was established, 242 miners died in mining accidents In 2012 the number of deaths had dropped to 36 Training the people who work in the mining industry – and retraining annually – helps reduce deaths, injuries and illnesses – Mine Safety and Health Administration Welcome to your new active training handbook!MINE SAFETY TRAINING HANDBOOK Mining Health PowerPoint Template With Mining Open Pit Diamond Mine Themed Background And A Gold Colored Foreground Design Slide 1 of 18 Title slides's text position: › Foreground style: Design 2 Diamonds Cut Dig Scoop Activity Related Templates 93% of Fortune 1000 companies use ourPowerPoint Template: mining open pit diamond mine
