Mining Methods: Block Caving Geology for Investors

What Is Block Caving?Why Use Block Caving?How Does It Work?Potential ProblemsFurther ReadingBlock (gravity) caving is a bulk underground mining method, which allows large low-grade deposits to be mined underground. This method involves undermining the orebody to make it collapse under its own weight into a series of chambers from which the ore extracted. It is a useful technique to extend the life of large deposits previously mined by open pits, and it is a method increasingly proposed for new mines around the world. 在geologyforinvestors上查看更多信息发布日期: Mar 15, 2017

Ore Body CharacteristicsAdvantagesDisadvantagesMine DevelopmentGround SupportProduction RateEquipmentMaterial HandlingSublevel Caving LayoutSublevel Caving SafetySublevel caving is a relatively safe mining method since the operations take place in small areas at a time and are highly mechanized. The uniformly distributed nature of generally 5mx3.7m sublevel nature of drifts aids in the safety of this mining method. To increase the stability of drifts in competent rock is controlled by smooth blasting and shotcrete, whereas less competent rock is affected positively by reinforcement, smooth blasting, shotcrete, and rockbolts.

Jun 14, 2019· This mining method can be applied to numerous types of ore bodies with inclination from horizontal to vertical. If ore body is narrow its inclination should be steep in order to apply the method. It is desirable that ore is strong enough to minimize support requirements for sublevel drifts, while surrounding rock mass should be prone to caving.

Mar 09, 2018· Sublevel caving is a large-scale mining method, suitable for large ore bodies with a steep dip. The setup is similar to long-hole stoping except loft raises are not required. Also, mining starts at the top of the ore body and progresses downwards in a safe sequence. Sublevels are developed in the orebody at regular intervals, with each sublevel

Underground mining (hard rock) Wikipedia

Bulk mining methods . Block caving is used to mine massive steeply dipping orebodies (typically low grade) with high friability. An undercut with haulage access is driven under the orebody, with "drawbells" excavated between the top of the haulage level and the bottom of the undercut. The drawbells serve as a place for caving rock to fall into.
