为了更为合理的探测和解释陷落柱的空间信息,解决煤田陷落柱的综合探测和解释的精确度及准确度的难点问题,基于煤田矿井陷落柱的发育特征,采用地面和井下综合探测识别技术,通过地面的~(210)Po探测、三维地震勘探和瞬变电磁法探测技术确定陷落柱的范围,利用井下三点源超前探测、无线电透视技术等综合探测手段,更加准确判断陷落柱的具体位置、影响范围等信息。陷落柱综合识别技术的应用,使其的解释精度和准确度均有提高,为矿井的安全生产提供了地质依据。
In order to detect and interpret the spatial information of the collapse column more reasonably and to solve the difficulties of the accuracy and accuracy of the comprehensive exploration and interpretation of the collapse column in the coal field, based on the development characteristics of the collapse column in the coal mine pit, the integrated detection and recognition technology The scope of the collapse column is determined by ~ (210) Po detection, three-dimensional seismic exploration and transient electromagnetic detection technology on the ground. Comprehensive exploration methods such as three-point downhole source prospecting and radio radiography are used to determine the exact location of the collapse column Location, scope of influence and other information. The application of the comprehensive identification technology of the collapse column improves the accuracy and accuracy of interpretation and provides the geological basis for the mine safety production.
