采场断层防水煤柱合理宽度研究

Study on the Reasonable Width of Waterproof Coal Pillar for Stope Faults

摘要: 根据影响采场断层防水煤柱宽度的因素,指出采场断层防水煤柱宽度应包括矿压影响区煤柱宽度和断层影响区煤柱宽度,并采用弹塑性极限平衡理论、流体力学和土力学理论,从力学角度分别严格推导了各影响区宽度的计算公式,提出了采场断层防水煤柱合理宽度的计算方法,为以后矿井的防水工作提供理论指导。

Abstract: According to the factors which affect the width of waterproof coal pillar for stope fault,this paper pointed out that the width of waterproof coal pillar for stope fault should include the coal pillar width of mine pressure and fault affected zone.By using elastic plastic limited equilibrium theory,hydromechanics theory and soil mechanics theory,this paper derived rigorously the formulas of each affected zone width from the mechanical points,and proposed the calculation method of waterproof coal pillar for the width of stope fault,which could provide theoretical guidance for mine waterproofing work in the future.
