Abstract

Abstract: In order to study the surface movement law of Wangjiata Coal Mine,a surface movement observation station is established above No.3101 working face of the mine.Through observation and study,it reveals the distribution pattern of surface subsidence basin under the conditions of shallow mining depth and high speed of coal mining,besides that,the relevant rock movement parameters are obtained,which can provide reliable reference for rationally retaining coal pillars and guiding relocation of the surface of the mine.

Key words: Mining subsidence, Surface movement deformation, Observation station, Rock movement parameter
