## Mathematical modeling of seismic explosion waves impact on rock mass with a working

Article preview

In the article, within the framework of the dynamic theory of elasticity, a mathematical model of the impact of seismic blast waves on rock mass is presented, including a working. The increase in the volume of mining operations in complex mining and geological conditions, taking into account the influence of the explosion energy, is closely connected with the analysis of the main parameters of the stress-strain state of the rock massif including a working. The latter leads to the need to determine the safe parameters of drilling and blasting operations that ensure the operational state of mining. The main danger in detonation of an explosive charge near an active working is a seismic explosive wave which characteristics are determined by the properties of soil and parameters of drilling and blasting operations. The determination of stress fields and displacement velocities in rock mass requires the use of a modern mathematical apparatus for its solution. For numerical solution of the given boundary value problem by the method of finite differences, an original calculation-difference scheme is constructed. The application of the splitting method for solving a two-dimensional boundary value problem is reduced to the solution of spatially one-dimensional differential equations. For the obtained numerical algorithm, an effective computational software has been developed. Numerical solutions of the model problem are given for the case when the shape of the working has a form of an ellipse.

## Algorithm of calculation of stress-strain state of the roof taking into account optimal selection of parameters of technological schemes in conditions of the Starobinskoye deposit

Article preview

Mining of reservoir fields is associated with technogenic "perturbation" of a specific environment - a rock massif. This object is very complex in structure, different in mechanical properties and characterized by a wide variety of laws of change of its stress-strain state (SSS). Obviously, the study of parameters of mechanical processes in such media cannot be methodologically predetermined by the use of data only from full-scale experiments, or data only from laboratory studies or the results of analytical calculations.

## About one method of calculation of the stressed state of coal and roof at development of hollow coal seams

Article preview

The rock in a rock mass is in a tense equilibrium. This equilibrium is usually broken when mining operations are stopped. There are many theories related to rock pressure in the stoping zone. Obviously, the solution of problems on this subject is associated with the study of deformation and dislocation processes of rocks in the workings and mine shaft. Since it is difficult to conduct grandiose full-scale experiments, these problems have to be solved by new developed methods, which are very universal and informative.

## Calculation algorithm of layered massif to predict the stress state of the roof and the coal seam in the zone of mining operations

Article preview

A mathematical model of interaction of a multilayer massif with a thin coal seam, including initial resolving differential equations and boundary conditions, has been obtained. The developed algorithm of numerical solution is implemented in a computational program in which the input parameters are geological characteristics of the main and immediate roof, stiffness coefficient of the coal seam in the massif and the law of its change in the edge zone, stiffness coefficient of soil rocks, stiffness coefficient of fill material, layer thickness and ultimate deformations of the roof. Accordingly, the output parameters of the calculation program are: the response of the coal seam to the action of the load from the overlying massif (support pressure), vertical and angular displacement of the roof layers over the coal seam, vertical and angular displacement of the roof over the mined-out space, the ultimate span of the roof.
