Information × Registration Number 0212U001496, 0111U002810 , R & D reports Title Physicotechnical bases of power saving up technology of underground mining of thin and rather thin coal layers popup.stage_title Head Vladimir Buzilo, Registration Date 07-02-2012 Organization National Mining University popup.description2 In the given report the main research results are represented: 1) The algorithm of defining influential factors of mining method with energy-efficient technology of coal extraction from thin and ultrathin seams by underground mining method is developed; 2) For developing rational parameters of transporting cargo the model of energy-efficient transporting and technological schemes providing minimal loss of time due to a transport is developed; 3) The laws of rock convergence distribution in a longwall and also loading on hydraulic jacks of mechanized support, while the study of mechanized support interaction with wall rocks takes place, are set up; in the process of making experiment required monitoring and measurements were implemented; 4) The parameters of energy-efficient mining technology of thin and ultrathin coal seams in account with the shape of longwall face and structural heterogeneity of rock massif are justified.
