Optimal location of water level sensors for monitoring mine water inrush based on the set covering model

Abstract Water inrush is one of the major mining disasters that may lead to numerous casualties. The development of information techniques makes it possible to monitor the occurrence and evolution of water inrush. Then, locating monitors for water inrush becomes a primary problem.
