Study On Surface Movement Caused By Coal Mining Under The Conditions Of Fault

Mineral lines and ground movement observation mining caused by subsidence observation is very complicated, which is caused by mining subsidence and many geological mining factor. Under the complex geological condition, specially under the condition of faults, the surface subsidence's normal rule is covered and displays the special regularity.This article taked the influence of fault to the surface movement as major effect factor, After analyzing the influencing factors of inclination angle, fault throw and so on, Established vector prediction model based on the probability integration. Then, used the similar material modeling to build the horizontal mining similar model taked the faults as the major effect factor, meanwhile,used the observation methodthe of lens and theodolite to observe the model, analyzed the rules of surface movement and distortion in the situation of coal mining fault influence, confirmed the prediction model accuracy.
