Cox, R.M.


We very much enjoyed the article “Mine roof trusssupport technology.” It was like reading a mine roof-control history book with old photos and figures. This article purports to portray current truss technology. In reality, the roof truss systems discussed in this article reflect outdated and obsolete technology of the 1970s and 1980s. Even the figures and photos show truss hardware and systems that are obsolete and no longer in use. This article has generated significant confusion in the field. Please let us explain the application and mechanisms of the modern truss systems.
