摘　　要：为查明平顶山煤田二矿和吴寨矿寒武系灰岩地下水集中径流带赋存情况,在探明矿区地质断层发育特征的基础上,采用井下连通试验研究了地下水集中径流带的展布及成因和控水作用。研究结果表明:二矿和吴寨矿寒武系灰岩地下水流速达3 320.05 m/d,含水层渗透系数达36 911.11 m/d,证明了地下水集中径流带的存在;二矿逆断层及两侧断层破碎裂隙带的存在,是影响寒武系灰岩含水层集中径流带空间展布的关键因素;集中径流带总体上控制着寒武系灰岩地下水由西南向东北流动、自浅向深的运移。寒武系灰岩地下水集中径流带展布特征的确定,为类似条件煤层底板水害的防治奠定了基础。In order to ascertain the deposition condition of the concentrated runoff zone in the Cambrian limestone underground water in No.2 Mine and Wuzhai Mine of Pingdingshan Coalfield,based on the geological fault development features of the proved mining area,the underground connection test was applied to study the distribution and causes of the underground water concentrated runoff zone and the water control role. The study results showed that the flow velocity of Cambrian limestone underground water in No.2 Mine and Wuzhai Mine was3 320.05 m/d,the permeability coefficient of the aquifer was 36 911. 11 m/d and the occurrence of the underground water concentrated runoff zone was proved. The occurrences of the reverse fault and the broken crack zone in No.2 Mine would be the key factor affected to the space distribution of the concentrated runoff zone in the Cambrian limestone underground water. The concentrated runoff zone generally controlled the movement of the Cambrian limestone underground water from the south-west to north-east and from a shallow to deep. The determination on the distribution features of the concentrated runoff zone in Cambrian limestone underground water could set up the base to prevent and control the seam floor water disaster.
