block caving method of mining

Block caving is a mining method that relies upon natural forces to break the rock. The cave is initiated by an undercut where a large area beneath the mining block is removed; gravity induced stresses then develop within the rock, causing it to fracture. The fracturing process is progressive and affects the entire rock mass overlying the undercut.

What Every Mining Professional Needs To Know About Block

Oct 20, 2020 Described as the deep mining method of the future, block caving is an underground mass mining method that allows for the bulk extraction of large, relatively lower-grade ore deposits that are vertical in orientation. The method is an attractive alternative when planning to develop a new mine, or to extend the life of an open pit operation.
Block Caving Is The Mining Method In Which Masses Panels

Block caving is the mining method in which masses, panels, or blocks of ore are undercut to induce caving, permitting the broken ore to be drawn off below. If the deposit is overlain by capping or bounded by a hanging wall, it caves too, breaking into the void created by drawing the ore. In this method both the ore and the rock are normally involved in the caving.

Aug 03, 2020 2. Characteristics. (1) Caving mining method no longer divides the ore block into ore rooms and pillars, but takes the whole ore block as a stoping unit, and carries out continuous single-step stoping according to a certain sequence. (2) In the stoping process, the surrounding rocks are naturally or forcibly caved, and the ore is drawn in ...

Block caving is an underground mining method that uses gravity to exploit massive, steeply dipping orebodies located at depth, particularly those with disseminated mineralisation or that are low-grade in nature, but too deep to be extracted using open pit methods. Block
Types Of Underground Mining Method Comparison

Mar 16, 2017 Caving Methods of Mining. There are three distinctive methods of working large deposits that involve, in some way, the factor of caving. Slightly different names are in use, but those that are simple as well as descriptive are top slicing, sublevel caving, and block caving. In a discussion of these methods, three things must be borne in mind ...

Underground Mining Using

Underground mining block caving, bore hole, drift fill. Underground mining is carried out when the rocks, minerals, or precious stones are located at a distance far beneath the ground to be extracted with surface mining. To facilitate the minerals to be taken out of the mine, the miners construct underground rooms to work in.
