Pneumatic rock drills. Surface and underground rock drills, for light and heavy drilling jobs. From blast hole drilling, to quarrying, anchor and wedge hole drilling, raise driving and bolting, these rock drills offer an excellent power-to-weight ratio and performance.
The technical demands of underground hard rock mining operations are higher than for open cut, which is why we are collaborating with key mining machinery and technology manufacturers (OEMs) on three automated and continuous mining vehicles designed to create far greater rock stability and less variance in the quality of the ore we extract.

Epiroc's rugged face drilling rigs are built for blast hole drilling in underground mining and tunneling with a wide range of cross sections. Real operational economy Standard features like dual damping drills lengthen the lifetime of consumables, while the fast boom movement with great visibility maximize uptime.
The Clarabelle Mill in Sudbury, operated by Vale Inco, has the capacity to process thirty-five thousand tonnes of ore a day—leaving many thousand tonnes more of waste rock to deal with. Some of that waste can be used as backfill underground, but much of it is dumped into designated, government-approved lakes or manufactured tailings ponds.

Jun 19, 2016· The Abandoned Magnolia Mill Is Rich With Colorado Mining History. Colorado has a rich history in mining. Many a town and camp sprang up with the hint of fortune and faded away years or even months later when that dream of a fortune dried up. Hundreds of such remains of ghost towns and mining remnants lie scattered throughout the Rocky Mountains.
Artifacts found underground in a Michigan copper mine: 1) 8 lb. hammer head, 2) chisel used for cutting up large pieces of copper so they could be removed from the mine, 3) hammer/pick head, 4) two pieces of a broken copper chisel like number 2, 5) chisel head, 6) copper chiselings made in the process of cutting up large pieces of copper
Longwall mining is a highly mechaniz ed underground mining sys tem for mining coal. It set of longwall mining equipment consists of a coal shear er mounted on convey or operating
J.H. Fletcher & Co. is the world leader specialized in the custom design manufacture and global sales of mining equipment, roof bolters, drills, air handlers, beam setters, scaling machines, drill jumbos, industrial minerals, hard rock, coal, roof drills and scaling machines that improve safety and productivity in underground mines.
Deep mining on the Comstock in the 1860s and 1870s introduced new hoisting technologies such as large steam engines and high-speed cages. A system of air passages connected to the outside ventilated some mines and others used hand bellows or engine-powered fans. Early mines drained underground workings with tunnels or bucket bailers.
From overturned trucks to huge fires, as well as crushed vehicles Here’s a collection of some really mind boggling accidents that have occurred in the mining industry. Do you have the best gold mining equipment? 1. Dumper corner navigation fail Wrong turn, mate And now what? 2. Just how did he loose a gear? Looks like this truck is not going anywhere. Better call the towage! 3. No
Chapter 1: Mine Ventilation An Overview Page 1 Min-218 Reading Material A BRIEF HISTORY OF MINE VENTILATION by M.J. McPherson (Excerpts of Chapter from "Subsurface Ventilation and Environmental Engineering, "1993) Observations of the movements of air in underground passages have a long and fascinating history.
The Sandvik range of rock support drill rigs is designed for a wide array of hard-rock mining operations, tunneling and civil engineering applications. Thanks to on-board cement mixers, cement bag platforms, and optional cement silos and steel strand reels, the rigs can operate autonomously for
