Backhoe excavators are another nearly ubiquitous piece of equipment in construction, landscaping and mining. Often confused with standard excavators, backhoe excavators are backhoe loaders with an excavator boom attachment on the back of the machine. On the front of the backhoe is a large bucket or blade used to push, level and move soil and other materials.
Room-and-pillar mining A method of mining flat-lying ore deposits in which the mined-out area, or rooms, are separated by pillars of approximately the same size. Rotary drill A machine that drills holes by rotating a rigid, tubular string of drill rods to which is attached a bit. Commonly used for drilling large-diameter blastholes in open

There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.
safety for all other surface mining equipment. Extensive engineering data for all makes and models of large off-the-road haulage vehicles was solicited from manufacturers. Information was tabulated to identify specifications for width, height, weight, tire track, wheel base, type
