  • Opencast Mining (Quarrying): Methods, Advantages

    Opencast mining is also known as openput mining, opencut mining, surface mining and also as strip mining, the later term being commonly used in the USA for opencast mining of coal The overburden and the mineral, coal, are excavated in long strips of a few metres thickness and hence the operations are termed strip mining 2Opencast mining operations involve the removal of huge quantities of overburden, dumping, and backfilling of the excavated area These overburden deposits of waste material containing lowgrade ores are represented as mine spoil dumpsOpencast Mining an overview | ScienceDirect Topicsopencast stripmining operation that extracts multilayered coal seams, exercising a throwover method to the lowwall side to the north and advancing in a southerly direction The area was previously mined using a conventional underground bordandpillar method The mining complex produced a total of 304 Mt in the preceding financial year, aboutv118n5a1 Optimization of the loadandhaul operation

    In an opencast or strip mining operation, the run of mine (ROM) material is normally transported to the primary crusher by haul trucks, and in underground mining operations it is conveyed to the primary crusher Crushing equipment is important to the mining process because it reduces the use of precious excavated resources and eliminates theEscondida copper mining operation consists of two openpit mines, namely Escondida pit and Escondida Norte pit The Escondida pit is 39km long, 27km wide and 645m deep The Escondida Norte pit is 525m deep BHP Billiton is the operator of the mine with 575% interest Rio Tinto holds 30% stake in the mineTop 10 deep openpit mines miningtechnologyThe main objective in any commercial mining operation is the exploitation of the mineral deposit at the lowest possible cost with a view of maximizing profits The selection of physical design parameters and the scheduling of the ore and waste extraction program are complex engineering decisions of enormous economic significanceBasics of an open pit mine Mine
