摘要：

The mathematical model of hydrobreak of a coal layer is offered. The model includes two approaches: the equation of heat conductivity with mobile border of the unit of phases and statistical consideration of merge of defects with formation of a crack. The formula for calculation of length of a crack through pressure of a forced liquid and parameters of coal is received. The good consent of settlement and skilled sizes is received. The mathematical model of thermal processing of chinks is offered on the basis of a method of functions of Green. The formula for calculation of length of a crack through parameters of thermal sources and physical properties of coal is received. The mathematical model of processing of chinks is offered by water solutions of acids. The formula where all parameters can be defined experimentally in laboratory conditions is received and, thus, to estimate radius of chemical influence on a coal layer.
