巨厚含水层采动影响下矿井涌水量预测OA北大核心CSTPCD
Prediction of Water Inflow Under the Influence of Mining of Thick Aquifer
在地下采掘活动的影响下,导水断裂带未能贯穿含水层时,大井法计算的涌水量误差较大.针对这种情况,对复杂地质条件合理概化,建立导水断裂带未能贯穿含水层的水文地质概化模型,对大井法进行改进,将含水层概化为垂直方向上互不影响的两元结构,提出倒置非完整大井法,可以分别计算顶部和侧向的水量,使其更贴近实际情况;并结合相关理论进行推导,得出相应的数学模型.结合彬长矿区亭南矿和胡家河矿2个工作面的现场实测地质资料,应用该方法计算涌水量,并与实际涌水量进行对比,结…查看全部>>
Under the influence of underground mining activities,the water conducted zone can not penetrate the aquifer.So,if the large well method is used to directly calculate the water inflow,the error will become greater.In this case,the complicated geological conditions are reasonably generalized and the hydro-geological conceptual model is established.The aquifer is divided into two parts which are not affected by each other in the vertical direction.The top…查看全部>>
