中文摘要：
在阐明突水系数由来的基础上,指出突水系数是相对隔水层厚度的倒数,探讨了我国学者将0.06 MPa/m定为突水系数临界值的缘由,总结了突水系数的演变过程和各种突水系数计算公式的适用性。研究认为,当采深小于300m时,突水系数的计算可以不考虑矿山压力对底板的破坏深度,但在大采深条件下突水系数的计算应当考虑矿山压力对底板的破坏深度。
英文摘要：
On the basis of its origin,the paper indicates that the water inrush coefficient is the reciprocal of the rela-tively impermeable layer thickness, discusses the reason why Chinese scholars take 0.06 MPa/m as its critical value, summarizes its evolution,and reveals its applicability of a variety of formulas. In addition, studies show that when the mining depth is less than 300 re,the failure depth caused by the underground pressure on the floor may not be consi- dered in the calculation of the water inrush coefficient, while it should be considered under the conditions of great mining depth.
