浅议煤田水文地质抽水试验监理质量控制要点

Discussion on the key points of supervision quality control in pumping test of coalfield hydrogeological exploration

由于煤田地质勘查工作的大量实施,勘查单位对水文地质工作的忽视等原因,导致水文地质工作质量下降,矿井水文地质条件不能够很好地查明,最为明显的是矿井涌水量的预测数据较实际情况出入较大。抽水试验是获取水文地质参数的重要手段,监理通过对抽水设计、抽水层段及止水部位、洗井等各个工序质量控制点的有效控制,保证了抽水试验的质量,取得了良好的监理效果。

Due to the implementation of large number of the coal geological exploration work,the neglect of exploration unit to hydrogeological work and other reasons,the quality of hydrogeological work was declined,mine hydrogeological condition could not be well identified,and the prediction data of mine water inflow was quite different from the actual one. Pumping test is an important means of obtaining hydrogeological parameters. By the supervision of the construction quality of pumping design,pumping section and water stopping part,well washing and so on,the quality of pumping test was guaranteed and good supervision effect was achieved.
