利用声速测井曲线划分基岩层风氧化带——以金家渠煤矿首采区水文地质补充勘探为例

Acoustic velocity logging curve based compartmentalization for bedrock air oxidized zone——Taking supplementary hydrogeological exploration first mining area in Jinjiaqu for example

由于勘探目的不同和勘探精度的限制,以往的勘探工程未能充分对风氧化带含水层的水文地质特征进行详细探查,无法满足矿井防治水工作的需求.为保障矿井建设和生产安全,通过声波测井曲线对比,有效地划分出金家渠煤矿首采区水文地质补充勘探区的基岩风氧化带,并根据地面物探和地质成果验证,该结果可靠,为矿井建设和安全生产提供指导.

For the different exploration purposes and exploration accuracy restrictions,previous exploration projects have not fully explored on the hydrogeological characteristics of the aquifer in air oxidized zone,and it is unable to meet the needs of mine water prevention and control work. In order to ensure the safety of mine construction and production, bedrock air oxidized zone was subdivided effectively by comparison of acoustic logging curves in supplementary hydrogeological exploration area,the first mining area of Jinjiaqu coal mine;and according to verifications from the ground geophysical and geological results,the results can provide reliable guidance for mine construction and production safety.
