Square-set stoping is a flexible method; it can be accommodated to very irregular ore bodies, large or small, and permits following and mining offshoots of ore with minimum dilution and loss of ore. Waste can be sorted out and left in the gob. The method can be adapted where sudden changes in dip of the deposit occur and to following ...

Rich ore - Ore that contains a higher than average amount of the desired material to be mined. Rill mining - A stoping method used in steeply dipping ore bodies where the broken ore is washed down a chute by water. Ring drilling - A drilling pattern where a number of drill holes are drilled in a ring, often used for blasting.

The open stope mining method is widely used in mines with good mining conditions. However, when mining ore bodies above medium thickness, a large number of pillars and ore are used to support the goaf, and the ore recovery rate is low. Therefore, it is less used when mining high-priced ore deposits. As the ground pressure increases with …

By 1850 the mining industry had grown to employ about 12 000 miners producing some 1.5 million tons of coal. However, during the second half of the century the Ruhr mining companies, and the steel making plants upon which they depended, developed exponentially and by 1910 there were more than 400 000 miners producing some 110 …

First, the broken ore is covered by the overburden, and personnel and equipment ca nnot enter the inside of the caving zone. Second, with the progress of ore drawing, the caving ore and rock flow dynamically. Third, the ore-drawing height of the block caving method is generally large, so it is diffi-cult to realize a full-scale drawing test.

Primary Mining Method Sub-Level Longhole retreat. Information. The broken ore is generally mucked out of a stope until the brow is open. More rock is then blasted in order to keep the stope full. If the stope is not straight, it is mucked out completely before blasting over the curve in order to ease the remote mucking.

The density of a material is defined as the mass per unit volume. In mining applications we are interested in bulk density; that is, the density of mineable volumes of rock, inclusive of naturally occurring pore space or larger voids. Thein situbulk density includes the water naturally contained in the rock.
