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。
According to the factors that affect the width of waterproof pillars in stope, it is pointed out that the width of coal pillar in fault stope should include the width of pillars and the width of pillars in the area affected by the pressure, and the elastic-plastic limit equilibrium theory, fluid mechanics and soil mechanics Theory, respectively, from mechanics point of view, respectively, the calculation of the width of the affected area is strictly deduced, and the calculation method of the reasonable width of the coal seam waterproofing pillars is proposed to provide theoretical guidance for future mine waterproofing.
