【Abstract】 This paper suggests three optimal programmes for reforming the existing controlnetworks in mine fields according to optimal design theory and the characteristics ofexisting control networks. Appropriate computer programmes are also designed. The ra-tionality and practicability of these optimal programmes are illustrated by practical exam-ples. These programmes are equally applicable to the optimal design of other controlnetworks for engineering survey.更多还原
