Abstract
The mechanism of formation of technogeny cracks (cracks of stratification and perpendicular flog cracks), including water spending is stated at primary and repeated mine layers of massif of rocks on coal deposits. It is shown possibility of application of a method of typical curves for an estimation of development of technogeny water spending cracks.
