Opencast Mining - an overview ScienceDirect

Opencast mining operations involve huge quantities of overburden removal, dumping and backfilling in excavated areas. A substantial increase in the rate of accumulation of waste dumps in recent years has resulted in greater height of the dump for minimum ground cover

Optimization of Blasting Parameters in opencast Mines

Drilling and blasting are the major unit operations in opencast mining. Inspite of the best efforts to introduce mechanization in the opencast mines, blasting continue to dominate the production. Therefore to cut down the cost of production optimal fragmentation from properly designed blasting pattern has to be achieved. Proper adoption of drilling and blasting can

Opencast coal mining: process and method Opencast mining, a method of mining introduced in 1942 to maintain coal supplies du ring the Second World War, is a quarrying method that is viable where a coal seam is relatively near the land surface or where a pit can expose a number of seams within an acceptable depth (normally up to 100m in the UK). The rock lying over and under each seam (the

Coal Mining and Local Environment: A Study

05.09.2017  Coal mining, especially opencast mining and the evacuation of coal, requires large tracts of land for extraction processes, industrial purposes such as thermal power plants and captive plants, as well as ancillary processes such as OB dumps, pipelines, railway lines, and public works. It destroys not only the standing forests but also animal corridors, which diverted the streams.
