DEVELOPMENT AND SUBSTANTIATION OF ROCK GROUTING PROCESS AT CONSTRUCTING PERMANENT OPENINGS

By Peter Serafimovich Syrkin

Abstract

Mechanisms determining filling of cracks with a plugging material have been established. Means of controlling the state of a rock mass and a grouting process have been developed on the basis of the established physical mechanisms of changing rock mass properties. A a result, water inflows have been decreased down to the standard ones (5 m*993/h) and the stability of the rock mass has been increased 1,5 to 2 times in eight mines in Kuzbass and one mines in Eastern Donbass.Available from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
