摘　　要：为了研究充填开采工作面矿压显现规律,以新阳矿10203充填开采工作面为试验背景,运用数值模拟软件,对工作面不同推进距离下,沿倾斜和走向方向的受力以及充填体上覆岩层的垂直位移进行了模拟分析。结果表明:与传统垮落法开采相比,充填开采来压步距增大,矿压显现缓和;采后及时充填可降低顶板下沉量。In order to study the mine strata pressure behavior law of the backfill coal mining face, base on No. 10203 backfill coal mining face of Xinyang Mine as the trial background, the numerical simulation software was applied to the simulation analysis on the stress along inclined and strike direction and the vertical displacement of the overburden strata above the backfilled material mass under the different advanced distance of the coal mining face. The results showed that in comparison with the traditional caving method mining, the roof weighting distance of the backfill mining was increased and the mine strata pressure behavior was relaxed. A timely backfill after the coal mining could reduce the roof subsidence.
