山区地表建筑物群下限高条带安全开采研究

为有效地控制地表移动变形以保护地表建筑物安全,最大限度地在山区丘陵地带开采建筑物群下压煤,基于协调开采的原则,结合现场实际情况,对川煤集团杉木树煤矿采用条带开采的方式,通过压力拱、威尔逊和关键层理论分析,得出了合理的条带开采参数。

Study on Mountain Surface of Strip Mining and Limit Height under Buildings

Strip mining is an avialable approach to control surface movment and deformation efficiently which is benefical for safety of the buildings with harmonized mining discilpine combined with in-situ geological condition which is hilly land in Shanmushu coal district,Sichuan coal mine corporation,we adopted comprehensive methods including theortical analyses,like stress arch,wilson and critical layer,rational parameters of srip mining have been formed.
