随着陕北矿区的开发，薄基岩、浅埋煤层条件下开采的萨拉乌苏组生态含水体保护已经成为矿区水资源和生态环境保护的关键问题。浅埋煤层薄基岩条件下开采覆岩破坏规律具有其特殊性，以关键层断裂及结构失稳形成的纵向切落裂缝破坏为特征，理论和开采实践证明，这种裂缝损害在一定程度上受煤层的开采厚度、顶板管理方法及开采方法的影响。本文以陕北榆神矿区的地形地质条件、煤层赋存条件、萨拉乌苏组含水层分布情况及地表裂缝破坏现状为背景，以王家沟煤矿1501、1502综采工作面为研究对象，研究条带填充协调开采方法和一次采全高开采方法覆岩破坏演化规律，分析应用条带填充协调开采方法控制覆岩导水裂隙带高度的条件和效果。 在研究分析煤层埋深、开采方法、开采厚度和条带填充协调开采对覆岩破坏形态，导水裂隙带发育高度影响的基础上，建立了覆岩导水裂隙带发育高度的控制模型，为提高覆岩结构的稳定性提供了理论依据；结合覆岩导水裂隙带发育高度的控制模型，应用室内物理相似材料模拟实验方法，UDEC和FLAC数值模拟计算方法，模拟在采用条带充填协调开采与非条带充填开采两种不同开采方法的条件下，关键层结构稳定性及覆岩破坏形态，覆岩应力应变分布规律、覆岩破坏演化过程、形成机制、导水裂隙带的发育过程及对隔水层的影响，揭示了关键层结构破断切落失稳是形成地表沉陷裂缝破坏、萨拉乌苏组生态含水层破坏的控制因素，在相同的地质采矿条件下，应用条带充填协调开采方法能够有效提高关键层结构稳定性，控制覆岩导水裂隙带的发育高度。 研究结果表明，在陕北浅埋煤层条件下，应用长壁综采工作面条带填充协调开采方法，能够有效的控制覆岩导水裂隙带发育高度，是保护陕北矿区萨拉乌苏组生态含水层的经济、有效的保水采煤途径之一。

With the development of the mining area of shaanxi, thin bedrock, shallow buried coal seam mining under the condition of Sarah WuSu group of ecological containing water protection has become the key issue in the mining area water resources and ecological environment protection. Shallow buried coal seam mining under the condition of thin bedrock strata damage rule has its particularity, in order to form the instability of key strata fracture and structure of longitudinal cut crack failure for the characteristics, theory and production practice has proved that this kind of crack damage to a certain extent by the thickness of coal seam mining, roof control method and the influence of the mining method. In northern shaanxi yulin-shenmu coal mine areas of the topography and geological condition, coal seam occurrence condition, Sarah WuSu aquifer distribution and the present situation of the surface crack damage as the background, to Wang Gugou coal mine 1501, 1502 as the research object of fully mechanized working face, the band filling mining method to coordinate and a method of mining overall height mining damage evolution law of banding analysis application filling mining method to coordinate control of water flowing fractured zone height of overburden rock condition and effect. In the study of coal seam buried depth, thickness and strip filling mining method, mining coordinate mining of overburden rock failure pattern, water fractured zone height influence, on the basis of establishing the height of overburden rock lead water crack bring control model, in order to improve the stability of the strata structure provides the theory basis; Combined with the overburden rock lead water crack with development height control model, indoor physical similar material simulation experiment method, combining with the UDEC and FLAC3D numerical simulation method, simulations in the stripe coordinate mining and filling the stripe filling mining under the condition of two different mining methods, key stratum structure stability and strata failure pattern, stress and strain distribution of the overburden strata, the strata damage evolution process, formation mechanism, the development process of the water transmitting fissure zone and influence on water-resisting layer, reveals the structure of the key stratum instability is cut down formation fracture surface subsidence damage, Sarah WuSu group of the controlling factor of ecological aquifer destruction, in the same geological and mining conditions, the application of strip packing coordinate mining method can effectively improve the key stratum structure stability, control the growth of overburden rock lead water crack bring height. The research results show that under the condition of shallow buried coal seam of shaanxi, application of longwall fully-mechanized face strip filling mining method to coordinate, can effectively control the strata water and height of fractured zone is to protect the northern shaanxi Sarah WuSu group mining area ecological aquifer of economic and effective water coal mining.
