PREDICTION OF SUBSIDENCE USING COMPLEMENTARY INFLUENCE FUNCTIONS

Surface subsidence caused by high-extraction underground mining is described through complementary influence functions. The concept of complementary functions was introduced recently by Sutherland and Munson (6). This concept differs from other proposed concepts in that the surface displacement is the result of the combined contributions of mined and unmined zones. The approach eliminates computational difficulties experienced with the conventional influence functions in determining the deflections above the rib side, and in the application of influence functions to complex room-and-pillar configurations. The general analytical framework for complementary influence functions is reported here. The technique is illustrated with analyses of several case histories which include both longwall and room-and-pillar mine plans. (TRRL)
