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.
Jul 02, 2011· HOISTING J3010/3/13 Example 3.5 A hoist drum has a mass of 360 kg and a radius of gyration of 600 mm. The drum diameter is 750 mm. A mass of 1 tonne hangs from a light cable wrapped round the drum and is allowed to fall freely. If friction couple at the bearings is 2.7 k Nm.
The Blair hoist's physical advantage is that the drum diameter can be smaller than usual and, with two ropes to handle the load, each rope can be much smaller. The government mining regulations permit a 5 % lower safety factor at the sheave for mineral hoisting with Blair hoists. This came about from a demonstration by the 189

Mining engineering of the Siegerland ore mining in the 19th century. At the turn of the 19th century a drastic change in the mining methods used in the Siegerland Siderit District can be stated according to operating reports and descriptions from the middle of the 19th century.
Increased productivity, reduced energy consumption and better safety in production are the main challenges faced by mining companies. As a leading mine hoist system supplier, ABB has more than 70 years' experience, and has delivered more than 600 new mine hoists and undertaken the modernization of hundreds of existing hoisting plants worldwide.
A common trend in underground mining is that mines are going deeper and payloads are increasing. Extracting minerals from below the earth takes big, and very specialised, hoisting gear. The choice of most productive and sustainable hoist system depends on depth, needed capacity and loads.
