Experimental Research on Static Earth Pressure Coefficient Distribution Rule of Deep Soil

One of the theoretical and technical puzzle of deep coal mine design and construction is the computation and prediction of static earth pressure. The present high pressure experimental research and analysis of undisturbed deep soil indicate that the static earth pressure of thick overburden is considerable different from that of superficial soil. It is necessary for deep coal mine design and construction to consider this particularity of earth pressure so as to avoid engineering accident and heavy lose of lives and property.
