A simple machine, the Joy loader featured two arms attached to the front of a short conveyor belt. The arms moved in a wide sweep, gathering loose coal and scooping it onto the conveyor belt, which then deposited the load into a shuttle car. Inventor Joseph Francis Joy (September 13, 1883-February 1957) was born in Cumberland, Maryland.

Conveyor Systems are mechanical devices or assemblies that transport material with minimal effort. While there are many different kinds of conveyor systems, they usually consist of a frame that supports either rollers, wheels, or a belt, upon which materials move from one place to another. They may be powered by a motor, by gravity, or …
Monitoring conveyor belts by the machine vision technique can improve the detection efficiency and precision, so it has attracted much attention. In this paper, the on-line belt monitoring technology based on machine vision is investigated to detect belt deviation and longitudinal rip of conveyor belts. 1.1. Machine vision and belt monitoring.
The belt conveyor is the most commonly used conveying equipment in the coal mining industry. As the core part of the conveyor, the belt is vulnerable to various failures, such as scratches, cracks, wear and tear. Inspection and defect detection is essential for conveyor belts, both in academic research and industrial applications. In …

Continental conveyor belts are designed from the inside out to endure the everyday working abuse of tons of coal, aggregate, wood and hard rock. Layers of specially designed fabric plies are sandwiched between rubber skim coats for adhesion and load support. Bottom and top cover compounds are added for maximum protection of the belt carcass.
The scraper conveyor is the key coal transportation equipment on the coal mining face. The conveyor often encounters the influence of abnormal working conditions, such as stuck chains, broken chains, and impact loads, which have a great effect on the smooth operation of the scraper chain and seriously affect the safety of coal production. If …
Machines then tip the coal onto a conveying system connected to the surface. Tram speed and conveyor width determine how quickly companies can collect and distribute coal to customers. Narrow conveyor width slows down the process, a factor that companies should consider during the mine construction phase.

Machine-driven conveyors caught on quickly and began appearing in all sorts of industries, though it would still be almost 100 years before they would work in mining operations. Railcars were still the preferred method of moving aggregate and coal from within mines to surface operations for much of the 1800s.
