房柱式开采采空区覆岩移动变形规律的模型试验研究

The Model Experiment Research of Overburden Rock Migration and Deformation Law of Gob Area with Room-and-Pillar System

本文以山西省阳城至关门高速公路下伏的蒿峪煤矿采空区环境条件为基础,运用相似材料模拟实验的方法,初步探讨了在不同等级荷载作用下,房柱式开采所形成老采空区的再次变形和冒落的规律,以及影响范围和深度。

Taking the old goaf of Haoyu under Yangcheng to Guanmen highway in Shan Xi province as a test example and adopting several research methods（such as experiment of analog simulation and numerical simulation）,under the different rank loads and the room-and-pillar mining condition,the rule of old gob area＇s second settlement,caving and the influence and depth under load is preliminarily discussed.
