In the process of hydraulic fracturing (HF), pressurized fluid is supplied to an isolated interval of the well. This causes the formation of an artificial crack, the growth direction of which greatly affects the method efficiency. It is especially important to take this into account when designing in-mine hydraulic fracturing for the solid minerals development. In this case HF is carried out close to underground workings and other inseam boreholes and these factors can influence the stress-strain state of stimulat...
