Abstract: In order to explore the top coal release law of the fully mechanized top coal caving face under different inclination angles， the 0291 fully mechanized top coal caving working face of Tangshan mine is taken as the research background， and the comprehensive research method of theoretical analysis， numerical simulation and physical similarity simulation experiment is adopted. Firstly， the parabolic equation of the coal-rock boundary equivalent to the area of the release ellipsoid is established fo... More
