煤矿井下综合物探超前探测技术与应用
|
摘要
为了查明掘进巷道前方是否存在异常区,排除富水构造给煤矿生产带来的潜在安全隐患,采用矿井瞬变电磁法和高密度电法超前探测方法,探查巷道掘进前方的地质情况。巷道超前探测、超前预报对于煤矿的安全掘进有着非常重要的作用。通过实例说明,采用综合物探手段对掘进巷道超前探测,可以达到仅采用一种物探手段而不能达到的效果。在实际工程勘探中,可以准确反映出巷道前方地质异常体的空间特征,为矿井防治水害提供了依据。
In order to ascertain anomaly area which was in the front of the gateway heading face,to remove the abundant water structure would bring the potential safety dangers to the mine production.The paper provided the conception of mine transient electromagnetic method to pilot explore the taper space of the gateway heading face.The mine transient electromagnetic method and high density resistivity were applied to survey the geological conditions in front of the gateway heading face.The application examples indicated that the use of combined geophysical prospecting technique for the advance detection of anomaly area in stone drifting can achieve the results which cant be attained by only using one geophysical prospecting means.In a prospecting living example,the spatial feature of anomaly body can be reflected exactly using the methods in advanced detection,thus it provides a foundation for mine water control.
