摘要: 为研究王家塔煤矿地表变形规律,在该矿首采3101工作面上方建立了地表移动观测站。通过观测与研究,揭示了在煤层埋藏浅、开采厚度大、推进速度快的开采条件下的地表下沉盆地的分布形态,并求取了相关的岩移参数,为合理留设煤柱及指导地表搬迁提供了可靠依据。

关键词: 开采沉陷, 地表移动变形, 观测站, 岩移参数

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
