摘　　要：为研究近距离上保护层开采覆岩移动规律及被保护层应力变化规律,以老石旦矿地质资料为背景,通过相似材料模拟试验,探讨17_(-1)煤层开采对13煤层煤顶底板条件、应力变化及瓦斯卸压等方面的影响。通过模拟研究,得出了17_(-1)煤层覆岩运移规律及垮落特征、13煤层应力变化特征及瓦斯卸压运移储集规律。为相同地质条件的含瓦斯多煤层开采提供理论参考依据。In order to study the law of overburden overburden and the law of stress change in theprotective layer after the mining, discusses the 17_1 coal seam mining of 13 coal seam roof and floorconditions by using similar material simulation test with the background of the Laoshidan geologicaldata, stress changes and gas pressure relief and other aspects of the impact. Through the simulationstudy, has obtained the initial collapse step and the period of the collapse of the overburden, the law ofthe overlying rock movement and the collapse characteristics, the stress variation of the 13 coal seamand the gas storage pressure migration. And provide the theoretical reference for the same geologicalconditions.
