摘　　要：为评价裴沟煤矿33采区二_1煤底板水害影响程度,统计了33采区地质及水文资料,详细分析了底板太原组L7-8灰含水层、L1-3灰含水层、奥陶系灰岩含水层以及地质构造对矿井充水的影响。本区受滑动构造铲蚀作用,二_1煤与下部奥陶系灰岩含水层间距变小,并且叠加较大的断裂构造,造成奥灰水。应用临界突水系数法对本区奥灰水突水危险性进行评价,划分出奥灰突水威胁区和奥灰突水危险区,并对奥灰突水危险区的涌水量进行了预计,为采区防治水工作和矿井安全生产提供数据。In order to evaluate the influence degree of water damage in Ⅱ 1 coal floor of 33 mining area in Peigou Coal Mine, geologieal and hydrological data of 33 mining areas were sumarized, and the influence of L7-8 limestone aquifer, L1-3 limestone aquifer, Ordovieian limestone aquifer and geological strueture to mine filling water were analyzed. Under the action of sliding strueture, the distance between Ⅱ 1 coal seam and Ordovieian limestone aquifer was smaller, and the larger fault structure was superimposed, which caused the Ordovieian limestone water to be the focus of this area. Critical water inrush coeffleient method was used to evaluate the water inrush risk of Ordovieian limestone water, and this area was divided into Ordovieian water breakthrough threat zone and danger area. At the same time, water inflow in water inrush danger area was estimated, which provided data for water control and safety production of the mine.
