Abstract

Increased water flows are a complicating factor in the
construction and operation of underground mine workings. The article presents the results of studies carried
out to improve the effectiveness of waterproofing
measures to ensure the safety of mining operations during the construction and operation of underground workings. Prevention of groundwater inflows into mine workings can be solved by one of the methods of water suppression – plugging – artificial filling of cracks and cavities in rocks with various special grouting materials through wells under pressure. When performing plugging, cracks and cavities in rocks are filled with grouting materials through pressure wells that prevent the migration of groundwater. Grouting materials are characterized by various physical and mechanical parameters. The studied enclosing rock massif, represented by gabbroamphibolites, is characterized by simple hydrogeological conditions and moderate manifestation of modern geodynamic activity. However, despite the significant costs of material and labor resources, the effect of the performed waterproofing grouting measures turned out to be of very short duration. A comprehensive analysis of geodynamic conditions, geomechanical state, physical and mechanical characteristics of rocks of the enclosing massif and grouting material from the standpoint of synergetics allowed us to determine the reason for the low efficiency of the performed waterproofing measures. As a result of the research, the reason for the low efficiency of the performed grouting works was determined. It is established that in the plugged massif, represented by rocky rocks, with the manifestation of modern geodynamic activity, the tamponage material must have certain physical and mechanical characteristics. An original technology of grouting works for the object under study
has been developed.
