Highwall mining machine TEREX Mining

TEREX SHM SURFACE MINING SYSTEM OVERVIEW
Experience higher coal recovery with lower surface mining operating costs.
Terex SHM is a self contained, highly productive, cost efficient coal mining system. Designed with safety in mind, the system is operated and maintained exclusively on the surface, and at no time does any crew-member go underground, thereby providing a very safe work environment.

Terex SHM is also the first practical surface mining system that can mine parallel entries to predetermined depths. Like an auger mining systems the Terex SHM works before a highwall. However, unlike auger mining systems, the Terex SHM mines parallel entries, rectangular in section and up to 1000 feet or 305 meters deep.

This superior surface mining system yields the following benefits:
High Annual Capacity
Lower Per Ton Reclamation Costs
Higher Coal Recovery
Lower Total Costs
Minimal Out of Seam Ash Dilution
Terex SHM is generally operated from a bench that is created by the removal of overburden material and coal by way of contour surface mining around the perimeter of a coal seam. Other highwall applications include previously augered areas and trench mining.

In a contour surface mining application, a minimum bench width of forty-two feet is required, with fifty-five feet or more being ideal. The configuration of the Terex SHM is such that it is capable of surface mining coal seams ranging from thirty inches to sixteen feet in thickness and to depths of up to one thousand feet. The ability to mine this range of coal seam heights is accomplished by fitting interchangeable cuttterhead modules to the Terex SHM for low, medium, or high seam mining applications.
