This book gives a brief history and a general overview of the state of surface mining technology with topics ranging from the principles to surface mining methods systems and pit planning design It starts with the definition of surface mine and ends with
·It has been estimated that more than two thirds of the world s yearly mineral production is extracted by surface mining Surface mining is the preference for mining companies because removing the terrain surface to access the mineral beneath is often more cost effective than digging tunnels and shafts to access mineral resources underground
·Planning is one of the fundamental tasks for surface mine projects and it can play a critical role in the success and results obtained after the development and operationalization of the project
·The design of the mine also plays a role as the inclination of the ramps and the location of the dump site and plant influence the equipment selection The compatibility condition is an important one International Journal of Surface Mining Reclamation and Environment 19 1 41 56 Article Google Scholar
·Preparing a mine design involves three key items ore body mine plan and infrastructure The designer starts on the inside and designs outwards The ore body provided by nature and interpreted by geologists is the basis for the mine plan the mining method recovery sequence and productive capacity proximity to surface footprint
·Waste rock muck piles are used as energy absorption barriers in many surface mining applications such as berms at dumping points and at the crest of slopes and in windrows as traffic
·Open pit mining also known as open cast or open cut mining is a method employed to extract valuable minerals or geological materials from the surface of the Earth It is a prominent form of mining that involves the removal of overlying soil and rock to access deposits that lie beneath
·Mining Strip Open Pit Quarrying It has been estimated that more than two thirds of the world s yearly mineral production is extracted by surface mining There are several types of surface mining but the three most common are open pit mining strip mining and quarrying These differ from one another in the mine geometries created the techniques used
Dewatering is essential for the safe and efficient operation of quarries and open pit mines that extend below groundwater level Benefits of dewatering include better working conditions and greater efficiency of mining operations as well as improved geotechnical stability for example by allowing steeper side slopes Dewatering techniques can be divided into two main groups
Casting design for bench blasting in surface coal mines is a new focus and a fairly recent success This study aims at the development of a mathematical model to predict the throw of overburden material based on geological conditions of a bench and charges in blast holes The procedure derived on the basis of blasting theories and dynamics of the multiple particle
