In 1914 a contract was let for removing 8,000,000 cubic yards of stripping at the rate of 2,000,000 cubic yards per year to uncover 6,000,000 tons of ore for open-pit mining. It was contemplated that later work would require the additional removal of 14,000,000 cubic yards of overburden to make available for mining an additional 19,000,000 tons of ore.

In the world of mining, not all draglines are created equal. The heavy-duty machinery is used as a primary excavating tool in many surface mining operations worldwide. These highly productive and massive pieces of equipment offer the lowest material cost per ton and have an operating life span of 40 years. Pound for pound, draglines are the most productive and versatile machines in the mining
Get PriceThe yearly average in coal mining decreased to 30 fatalities from 2001-2005, though 60 to 70 miners still die each year in the U.S. coal and non-coal mining industry. The most common accidents occurring in the mining industry are the result of poisonous or explosive gases or mishaps relating to the use of explosives for blasting operations.

A bucket-wheel excavator (BWE) is a large heavy equipment machine used in surface mining.. The primary function of BWEs is to act as a continuous digging machine in large-scale open-pit mining operations, removing thousands of tons of overburden a day. What sets BWEs apart from other large-scale mining equipment, such as bucket chain excavators, is their use of a large wheel consisting of
