The experiments obtain that the key strata of bedrock in shallow seam has a significant effect on the stability of aquiclude and clay as well as loess aquicludes are key stratum of water-preserved-mining.

The results show that aquiclude of coal seam floor has obvious elimination to water head, and the actual water pressure exerting to the effective water resistant layer is lower than that of aquifer.

结果表明：隔水层的原始导高带对含水层水头具有较大的消减作用，作用于有效隔水层的实际水头压力远小于含水层的水头压力。
