针对潞安矿区漳村煤矿常隆水库下厚煤层综放开采安全与否问题,采用现场实测、工程类比等方法研究了综放开采导水裂缝带发育规律,计算了水库下采煤防水安全煤岩柱合理尺寸以及文王山南正大断层上盘安全隔离煤柱尺寸,分析了断裂构造对水库下采煤的影响,进行了水库下采煤安全可靠性分析,采用概率积分法和克里格差值法预测了水库下开采区域地表沉陷情况和采后水库区域扩大淹没范围.基于实测地表裂缝临界水平变形,预测了开采地表及水库底部地裂缝极限发育深度,分析了采动后水库渗漏可能性及开采对坝体采动影响.研究结果表明:水库下综放开采留设防水安全煤岩柱尺寸是足够的,采取合理的安全技术措施可实现水库下综放顶水开采,受地表沉陷影响水库淹没范围有一定幅度增加,水库下综放开采地裂缝极限发育深度为7.8 m,不会导致库区渗漏和库内水位骤降,可以达到地表水资源保护和水库下采煤的双重效果.%In order to solve problem of high-seam mining under Changlong reservoir with fully-mechanized mining in Zhangcun Coal Mine at Lu'an Minefield,the developing rule of water flowing fractured zone was studied by way of field measurement and engineering analogy.Analysis on safety mining under reservoir was done by calculating height of waterproof pillar.The size of pillar to prevent normal fault of South of Wenwangshan was designed,and influence of the fault on mining under water was analyzed.Mining subsidence was predicted with probability integral method,and Kriging Analysis was applied to define the reservoir inundated area.The limit depth of mining ground fissure was predicted based on in-site critical value of ground horizontal deformation,and by which mining influence on dam and leakage in reservoir area was analyzed.It was stated that height of water proof pillar was enough for mining under reservoir,and safety technical measures could be well used.The extent of reservoir inundation increased.The limit depth of mining ground fissure was about 7.8 meters,and leakage and rapid drawdown of water level of reservoir won't happen.It is safe to mining under Changlong Reservoir,and the ground water resource was protected at the same time.
