摘　　要：文章基于黑龙江鹤岗煤田河流下开采的覆岩三带的划分展开研究,采用规程、多元回归以及覆岩三带划分专利技术三种方法对该区域井田范围内南、北以及断层附近的三个钻孔进行计算。首先计算该区域内一矿井投产时开采的25#煤层覆岩三带,其次考虑多层煤综合开采时覆岩三带的发育高度。计算结果表明,结合钻孔柱状图认为不论是单独开采25#煤层还是综合多层煤开采,地表河流对井下工作面开采几乎不会产生影响。Based on three zones division of overlying strata mining under river in Heilongjiang Hegang coalfield, 3 boreholes was selected from the south, north part and near the fault in the target area, and calculation was done on the boreholes using regulation, muhiple regression and patent technology of overburden three zones division. First, the three zones of overlying strata in 25^# seam was calculated, when it went into operation, then the development height of overlying strata three zones during multi - seam mining was analyzed. Calculation resuhs show that, combined with the bore histogram, the surface river has almost no influence on the underground mining, for single - seam mining of 25^# coal seam or multi - seam mining.
