Shaft Mining: Shaft mining is a form of underground mining where shafts are pushed vertically from top to bottom to excavate the ores and minerals. It is also called shaft sinking. It is best suited for concentrated minerals such as iron, coal, etc. which can be found at the depth of the earth's surface. It is found mostly all over the world.

Conventional mine shaft sinking methods involve the performance of a cycle of different operations—drilling and blasting, removal of smoke and cleaning of fly-rock lodged on overhead timbers, mucking and hoisting of the broken rock, and timbering. The latter (a) may be the last operation of the cycle, (b) may be carried on during …
This mining equipment is designed with DTH hammer to impact and fracture rock, ensuring high drilling speed. 360° (±180°) rotation provides large drilling coverage, and the drilling depth can reach up to 100m. What's more, the DTH drilling rig can be expandable to drill holes for radial cable bolting, and also for shaft drilling.
From there the material can be transported out of the tunnel without problems. After each jacking stroke, the drilling process is stopped for a short time, to secure the pipe string and the drilling unit. Then the next jacking pipe can be installed in the jacking frame. When the desired drilling length is reached, the drilling unit is retracted.
East Mine. The shaft has a finishedinternal diameter of 4.3 m and when complete will be approximately 270 m deep. The upper 40 m of the shaft was constructed by blind-sinking a precast concrete caisson through Tauranga Group alluviums. Below 40 m BC the shaft wasconstructed by drill and blast methods through a series of rock strata.
