摘　　要：针对安家岭露天矿进入地堑后所引起的煤层下降、生产组织困难等问题,结合工作面布置方向不同位置的落差统计分析,提出3种延深工程方案,并对不同方案的总掘沟量和掘沟时间进行计算比较,结果表明N71700方案能充分利用地堑构造区的煤层赋存特点,使总掘沟量最小、掘沟时间最短,为最佳延深工程方案。According to the problem of coal seam decrease and production organization after entered graben in Anjialing surface mine, combined working face layout direction and different position fall statistical analysis, put forward 3 kinds of extension project, and for different schemes of total digging trenches and trench time calculation and comparison, the results show that the N71700 scheme can fully utilize the graben tectonic area coal seam characteristics, so that the total amount of the smallest trench digging, digging trenches for the shortest time, the best scheme of extension project.
