Information × Registration Number 0206U004409, 0103U001623 , R & D reports Title Searching the ways for control of cracking parameters in coal block for increase of efficiency of its degasification. popup.stage_title Head Bulat Anatoliy Fedorovich, Registration Date 21-02-2006 Organization The Polyacov Institute of Geotechnical mechanics of NAS of Ukraine popup.description2 The mathematical models of cracks growth are developed at a static and pulse forcing. The ability of control of the distribution a component of a rock pressure is proved at a liquid forcing in a most-tense coal layer by change of its characteristics of friction. The results of work will be used at the development of ways and technical facilities of extraction the methane from coal layers.5635 Product Description popup.authors popup.nrat_date 2020-04-02 Close
