摘要
为提前探明预采煤层顶底板附近富水区的分布情况、合理安排工作面的布设位置,并提前采取相应的预处理措施,采用ZONGE公司生产的GDP32^II型多功能电法仪,对李村煤矿二采区进行地面瞬变电磁法勘探,利用探测数据对顶底板影响区范围内3号煤层开采的第四系及基岩风化带、K10、K8及K7含水层内富水区域位置、范围和形态进行了解释与圈定,为煤矿安全生产提供可靠的水文物探资料。
In order to ascertain the distribution of water-rich areas in the roof and floor of pre-mined coal seam in advance,the working face layout was reasonably arranged and corresponding pretreatment measures were taken in advance.The GDP32 II multifunctional electrical method produced by ZONGE was used to conduct ground transient electromagnetic exploration in the second mining area of Licun Coal Mine.The detection data was used to explain and delineate the location,scope and form of the water-rich area in the Quaternary system and the bedrock weathering zone,K10,K8 and K7 aquifers within the influencing area in the roof and floor of No.3 coal seam,the results provided reliable hydrological geophysical prospecting data for the coal mine safety production.
