| Abstract |
The research was to show the feasibility of using plastic liners containing sand and other fillers as a means of roof support in coal and other mines. Phase I, directed toward determining which state-of-the-art resin systems might have utility as a means of roof support in a coal mine, consisted of a canvass of resin manufacturers to learn which resins were available commercially that might have utility for this application. The resins submitted by the manufacturers were evaluated in a number of simple tests to define which of them would be most suitable for roof support use. Phase II included experimental work directed toward better defining the utility of selected resins and, finally, extensive evaluation of two resins for usefulness as components of a mine support system. During Phase I a number of fillers (fibrous and particulate) were evaluated. In Phase II all work was done using concrete sand as the major filler along with a minor amount of chopped glass roving as a fibrous filler. |
