Study on Earthquake Resistance of Underground Reservoir in Mined-out Area of Mine
To study the change of stability and safety degree of mine goaf reservoir under vibration environment, taking Lijiahao Coal Mine as the research background, the stability and safety of the main parts of the goaf reservoir are analyzed and studied under the continuous existence of earthquake or other earthquakes by using the method of formula derivation and similar simulation experiment in laboratory. Since the dam body is a key part of supporting the normal operation of goaf reservoir, the dynamic response formula of the dam body under the action of earthquake is analyzed to obtain the dynamic response of the dam body under the condition of earthquake. At the same time, through the research of similar simulation experiments in the laboratory, the variation of the safety degree of the whole goaf after disturbance is obtained under the condition that the vibration in the goaf continues to exist. With the increase of seismic intensity, the overall safety of the reservoir decreases. And under the condition that the source location is known, the closer the source is, the less safe it is.
