Mechanism of “Hydrostatic Water-Inrush” and Countermeasures for Water Inrush in Roof Bed Separation of A Mining Face
摘要
Abstract
We analyze the water-inrush case in roof bed separation of a mining face and the basic formation conditions of water in bed separation.In addition, we summarize the type of water-inrush in bed separation and discuss the mechanism of hydrostatic water-inrush formation in roof bed separation of a mining face.The main induction factor of “hydrostatic water-inrush” in roof bed separation of a coal mine is the hydrostatic pressure.The key point of discrimination for water-inrush is the determination of water in mine roof bed separation and the thickness of relative water-resisting layer.The formation of water in mine roof bed separation and the occurrence of water in bed separation can be avoided through the following three kinds of approaches: 1) destroying the closeness of bed separation; 2) dewatering the recharge water source in bed separation before exploitation; and 3) dewatering recharge the water in bed separation before exploitation.The conducting borehole drilling and the closure borehole drilling are used for dewatering in bed separation.The reliability is verified in practical application.关键词
