    Open cast mining involves the removal of ore from seams relatively near the surface by means of an open pit (see figure below). These mines often occupy a large area of land for excavation of the ore and disposal of the overburden (the waste rock lying over the ore). This kind of mining operation typically involves the following 4 stages: 1.

    Opencast Mining an overview ScienceDirect Topics

    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 area and also given rise to danger of dump failures. Further, steeper open-pit slopes are prone to failure. These failures lead

    Backfill RockEng

    Backfill Backfilling is a common practice within many underground mines. Basically, this process consists of returning material removed during extraction to the underground part of the mine. Often backfill material (mostly crushed rock) has a binder, like cement, added before being reintroduced to the mine to help it settle and stabilize. Backfill is placed in worked-out areas of the mine
