针对郑州矿区“三软”煤层地质采矿条件，结合“三下”采煤技术，提出了杨河煤业魔洞王水库下隔离开采的开采方案，确定了水库下采煤工作面的推进方向和速度，并给出了水库和堤坝保护煤柱范围内合理的开采厚度。通过导水裂隙带高度计算，分析了水库下采煤的安全性。工作面采用综采放顶煤一次采全高，工作面大致为由东向西推进，与水库大坝长轴走向基本一致，经首采工作面试采实践证明开采方案安全可行。

Aiming at the geological mining conditions of"three soft"seam in Zhengzhou mining,combining with the"threeGunder"mining technology,the paper put forwards the mining scheme of isolating mining under the Mowangdong reservoir for Yanghe Coal Mine?It determines the advancing direction and speed of the working face during mining under the reservoir and presG ents rational mining thickness within the range of protective coal pillars of reservoir and dam?Through calculating the height of the water flowing fractured belt,this paper analyzes the securiG ty of mining under Mowangdong reservoir?FullyGmechanized and fullGseam cutting is adopted in the working face,and the advancing direction is from east to west generally and the trend is basiG cally same with the long axis of the Mowangdong reservoir? The mining practice of the first working face proves that the mining scheme is safe and feasible.
