Abstract

The stress–strain behavior of piecewise-homogenous rock mass surrounding a horizontal longwall is defined by the natural stress field and by mechanical constants of rocks and coal. The developed algorithm of successive approximations for the characteristics of rock mass with a longwall integrates all known partial algorithms into a class of difficult problems. The authors propose solving inverse problems by identification of top coal caving parameters from the numerical experiment and using additional information on geomechanical behavior of coal seam ahead of face.
