It has been established that the design of the technology for securing the workings consists in determining the totality of the processes of manufacturing, transportation, construction of temporary and permanent fastening that are interconnected in time and space. The proposed a model for finding the optimal type of fastening from the position of minimizing the cost of construction and maintenance of workings. The idea is to present the stages for the construction of workings in the form of a network model and the use of dynamic programming algo-rithms to optimize the process at each intermediate stage. This allows you to move from diversity (by nature) to priority control factors that affect the efficiency of the process - in this way, optimization of the parameters of the workings con-struction process is achieved. Particular attention is paid to the study of the behavior of the massif in complex hydrogeological conditions. De-pending on the type and manifestation of groundwater, various assessment criteria are taken into account: water inflow, filtration, water permeability, etc. Based on ideas about the hydrogeological characteristics of the rock mass, it is possi-ble to analyze the appropriateness of using this or that type of fastening taking into account auxiliary steps. Conversely, based on the type of attachment available, the behavior of the rock mass can be predicted. Thus, the problem of ensur-ing the stability of workings in complex hydrogeological conditions is included in the class of problems of dynamic pro-gramming and is associated with the study of technological aspects of the physics of mountain processes. A characteristic feature of this problem is the presence of reciprocal relationships between the construction technology and mining and geological conditions, when the hydrogeological characterists Product Description popup.authors Vynohradov Yurii O.
