• Size of entries and crosscuts vary from mine to mine – determined by size of equipment employed – thickness of overburden – coal seam thickness – ground control – surface protection requirements • Entry and crosscut widths generally range from 15 to 25 feet • Pillar sizes will generally range from 30 to 100 feet and have a rectangular configuration • Extraction Ratio is ...
In both conventional and continuous methods, coal is loaded onto coal transport vehicles and then dumped onto a panelbelt conveyor for transport out of the mine. Once the coal has been cut, the strata above the excavated coal seam are supported by roof bolts. Under favorable conditions, the production from a continuous miner section can exceed 800,000 tons per year per continuous miner.

Crushing. McLanahan offers a variety of crushing solutions to reduce minerals such as coal, salt, granite, copper and iron. Minerals are liberated from the waste rock and reduced in size through the primary, secondary and tertiary stages of crushing, by equipment that utilizes impact, attrition, compression or shear forces.
· The belts you see on the conveyor lanes in grocery store checkouts, for example, are much smaller in width and length than the ones you'd find under ground transporting product from the mine. While many belts can be custommade to fit a certain desired length and width, it's always best to know your sizing requirements.

A minecart or mine cart (also known as a mine trolley or mine hutch) is a type of rolling stock found on a mine railway, used for moving ore and materials procured in the process of traditional are seldom used in modern operations, having largely been superseded in underground operations (especially coal mines) by more efficient belt conveyor systems that .
· Current regulations for fire suppression systems in underground coal mines to protect conveyor belt installations have been in place since the Coal Mine Health and Safety Act of 1969 was enacted. Over time, the coal conveyer equipment being used and ventilation conditions underground have changed significantly, particularly the width of the conveyor belts and the use of belt .
· The shaft complex comprises three shafts an incline shaft bringing coal to surface via a conveyor belt system, a ventilation shaft and a men and materials shaft. The Van Dyks Drift beneficiation plant has also been expanded to process North Shaft coal which is largely designated for the export market. Van Dyks Drift is the first South African mine to achieve 4 million fatalityfree shifts. 1 ...
underground coal mine workers. • During 1980–2005, over 39 billion in CWP benefits were paid to underground coal miners and their families. • Recent xray surveillance data for 2000–2006 show an increase in CWP cases. Nearly 8% of examined underground coal miners with 25 or more years of experience were diagnosed with CWP.
Belt Feeders. FEECO offers heavyduty belt feeders that are capable of handling nearly any material. Belt feeders are commonly used when material that is either stockpiled or loaded (at an uncontrolled rate) in a bin or hopper needs to be introduced into the system at a controlled feed rate.

· A large coal mine is essentially an underground city, with railroad tracks and conveyor belts running for literally miles in every compass direction. The walls of a coal mine aren't black—they're white, covered with many layers of crushed powdered limestone called rock dust, required by law to suppress the omnipresent coal dust. The mine is a very cold, wet and .
· These mines employ strip mining methods in straight benches with conveyors moving regular material that doesn't need various mining techniques to successfully extract the ore.
