Essay

The arguments of new technology of anchoring water-loaded rocks with usage of high-head cement sprays are advocated. The dependence of depth of a penetrance of a high-head spray in gentle rocks from stress and expenditure of fastening solution and their rational values is installed. On the basis of the pattern of two models with different module medium the algorithm of account of rational arguments of a shell of mine workings conducted in water-loaded rocks with usage high-head cement sprays is designed. The analytical dependencies linking a reserve factor of working protection shells from their geometrical characteristics and arguments of a shell are obtained. The technological schemas of anchoring based on creation of protection shells around of mining workings are justified. The results of the held studies realized by creating recommendations for support of mining operations with usage new technology of anchoring water-loaded rocks with usage of high-head cement sprays are advocated.
