地面物探在采空区及积水勘查中的设计与应用

Design and Application of Ground Geophysical Prospecting in Goaf and Water Logging Exploration

为了勘察斜沟煤矿13#煤层黄辉头一带可能存在的采空区和积水区,综合采用瞬变电磁法和活性炭测氡法进行地面物探。通过设备稳定性分析及噪声测试确定勘探设备及其参数,并设计勘探网络。勘探结果分析表明,勘探区中东部邻近边界侧可能存在1处部分充水的采空区,此外,全区还可能零散分布着6个积水区。该结果可作为煤矿规避风险、进行安全生产的理论依据。

In order to investigate the potential goaf and water-logged zone of No. 13 coal seam in Xiegou coal mine Huanghuitou don measurement and noise testing, a partially area, the geophysical prospecting is carried out by using transient electromagnetic method and ra- with active carbon. The equipment and its parameters are determined by equipment stability analysis and the exploration network is designed. The analysis of exploration results shows that there may be water filled gob near the boundary in the middle and east of the exploration area. In addition, there may be scattered water areas in the whole area. The results can be used as a theoretical basis for risk avoidance and safe production.
