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.

Underground Mining Methods And Equipment

Th e exploitation workings in caving methods are designed to collapse, with intentional caving of the ore and/or host rock. The three major caving methods are: • Longwall mining • Sublevel caving • Block caving Longwall mining is used in horizontal, tabular deposits (mainly coal), while the others
Mining Funda Block Caving

Block Caving. Block caving is an underground hard rock mining method that involves undermining an ore body, allowing it to progressively collapse under its own weight. It is the underground version of open pit mining. In block caving, a large section of rock is undercut, creating an artificial cavern that fills with its own rubble as it collapse.
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.

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.

Jun 15, 2018 7. Sublevel caving. Sublevel caving is a method often evaluated in parallel with block and/or panel caving options. It requires multiple levels of development and ongoing ring blasting for production. Sublevel caving allows for a more selective extraction but typically achieves lower production rates than block and panel caving methods.

Caving methods. Caving methods include block caving, sublevel caving, and longwall mining.For emphasis, allow me to repeat what I said earlier: caving methods are used in settings where the ore or the host rock is so weak that it cannot support its own weight for any period of time; the methods only work if the rock or the ore will readily cave under its own weight.
