Determining the dimensions of combined supports in roadways
2011The predominant amount of European coal deposits exploited underground is extracted by the longwall method with controlled caving. Experience shows that roadways, which ensure all transport and ventilation in coalfaces, restrict both output and safety, as well as economy in coal production. The problem is urgent especially in deep mining.

Strata loading of mine roadway supports
Mining Science and Technology, 1984Abstract Several tunnels and roadways in U.K. coal mines have been instrumented to establish an improved understanding of the general characteristics of rock pressure loading on steel supports in such excavations. The sites selected were in a depth range of 350–780 m below surface, whilst the geology was typically Carboniferous Coal Measures rock ...
