摘要
安全水压值是带压开采矿井安全生产的重要评价依据。目前煤矿通用的安全水压计算公式得出的安全水压计算结果与采煤工作面实际可承受的水压值存在较大差异。为了提高采掘工作面安全水压计算的准确性,利用解析法推导出新的安全水压计算公式,并提出了安全水压计算方法的选用建议,可以指导矿井进行采掘工作面带压开采安全评价,降低带压开采的突水风险。
Safe water pressure is important for evaluation of safe production. There is difference between safe hy-draulic pressure calculated by formula and the actual value, in order to improve accuracy of coalface safe pressure calculated by analytical method, the formula for calculating the safe pressure and calculation method of pressure were put forward, which can guide coal mining under pressure, reduce water inrush risk.
