Open Cut or Underground Mining Which is better?
Oct 21, 2017Opencut mining gets its name because that’s exactly what this type of mining looks like, a big open pit. This type of mining allows for the extraction of minerals that aren’t very far under the surface. The process keeps the activity from going deep underground. This has many advantages. Yet, it’s only viable when the materials are

Determination of coal pillar width for gob‐side entry driving in
It is concluded from ground pressure during the adjacent coal face mining that it is difficult to control roadway surrounding rock within 200 m away from the open-off cut. Therefore, this stone selects the haulage roadway (GED) within 200 m away from the open-off cut in 21215 coal face as research object.
