摘　　要：我国许多煤矿的水文地质条件复杂,开采过程中受到水害的严重威胁。电法勘探因其对水体敏感,在煤矿水害致灾因素探查方面得到了广泛应用。通过介绍井下电法勘探(包括井下瞬变电磁法、直流电测深法、直流三极超前探测法及音频电透视法)在煤矿水害致灾因素探查方面的技术特点及应用实例,探讨了井下电法勘探今后的发展方向。The hydrogeological conditions of many coal mines in China are complicated,and the mining process is seriously threatened by water hazards.Because of its sensitivity to water,electrical prospecting has been widely applied in the exploration of water disasters of coal mines.By analyzing the technical characteristics and application examples of underground electric prospecting（including underground transient electromagnetic method,direct current sounding method,direct current tripolar advanced detection method and audio electric perspective） in coal mine water disaster exploration,the development direction of underground electric prospecting was discussed.
