摘　　要：村庄下压煤是长期困扰我国煤矿发展的难题之一,如何科学、经济、合理的解放村庄压煤,是我国"三下"采煤的重要课题。巷道矸石充填开采是近几年发展起来的建筑物下压煤开采技术,由于其地面减沉效果较好,对农村民房起到了很好的保护作用。结合某矿巷道矸石充填开采及地表移动实测资料,分析了该技术应用的效果,并通过计算分析和曲线拟合,求出了该矿巷道矸石充填开采的地表移动预计参数。Mining under village is a difficult issue for the development of coal mine in our country. How to use a scientific, economical, rational method to mine coal under villages is a important topic of “under three” mining coal in our country. The roadway gangue filling mining is a new coal mining technology under buildings in recent years. It has a good protection to civilian buildings because of the good effectiveness of reducing subsidence. This article analyzes the application effect of the technology combing the field observation data. By computational analysis and curve fitting, the surface movement prediction parameters of the roadway gangue filling mining in the mine are also obtained.
