Task is to elaborate degassing techniques for coalseams for mining operations safety improvement and industrial methane utilization. The method of investigation is analytic using the data of experimental and natural seerveys. The model is proposed of gas emission of mined coal and rock strata with the methods of parameters calculation for braiding and barrier holes. The sphere of application is coalmines of Ukraine that extract gas - containing coalseams. Product Description popup.authors popup.nrat_date 2020-04-02 Close
