Coal mine bumps occur in most countries where coal is mined by underground methods. Coal bumps can be characterized as unstable releases of strain energy associated with energy changes that take place with progressive mining. This research is conducted to study the strain energy effect on coal bump problems associated with underground coal mining. The roofs are modeled as elastic beams on continuous elastic foundations subject to exponentially distributed abutment stress. Elastic beam theory is applied to develop analytical solutions for deflection of single-layer roof models. Methods for analyzing double layer roof and double layer foundation models are also discussed. Formulae for assessing critical spans of the roof beds and strain energ...
