煤矿底板突水评价突水系数–单位涌水量法

 在突水系数Ts基础上，引入反映充水含水层富水性的指标——单位涌水量q，并在大量突水实例统计分析基础上，对突水危险性与突水系数、充水含水层富水性之间的关系进行深入研究，得到一些规律性的认识；提出评价底板突水危险性的新方法：突水系数–单位涌水量法，作为突水系数法的补充，可为含水层富水性较弱而突水系数较大的深部开采底板突水安全评价提供参考依据。

WATER INRUSH COEFFICIENT-UNIT INFLOW METHOD FOR WATER INRUSH EVALUATION OF COAL MINE FLOOR

Based on the water inrush coefficient Ts,the unit inflow q,an index reflecting water bearing of the aquifer,is introduced. Based on statistical analysis of a large number of examples of water inrush,the relationships between water inrush potential,water inrush coefficient,and the water-enriched properties of aquifer are further researched. The achieved laws of water inrush are discussed. And a new method for evaluating risk of floor water inrush is put forward. The method of water inrush coefficient-unit inflow method can be a supplement for evaluating water inrush coefficients. The achieved results can be provided for evaluating water inrush risk of floor in deep mining of some mining areas,in which the water-enriched properties of aquifer are not obvious but water inrush coefficient is larger.
